Priority of the Chinese Patent Application, the entire contents of which is incorporated herein by reference.
技术领域Technical field
本发明属于通信技术领域，尤其涉及一种基于无线自组织网络的移动通信系统。The invention belongs to the technical field of communications, and in particular relates to a mobile communication system based on a wireless self-organizing network.
背景技术Background technique
常见的移动通信装置(如手机)之间相互通信大多借助蜂窝基站或者无线局域网(Wireless Local Area Networks，简称WLAN)接入点，在这些移动通信装置距离较近时再接入蜂窝基站或者无线局域网接入点以相互通信，不仅会导致通信成本上升，而且会加重蜂窝基站或者无线局域网接入点的负担。此外，蜂窝基站和无线局域网接入点并不总是可用的，在没有蜂窝网络覆盖的偏远地区或突发自燃灾害情况下，移动通信装置借助蜂窝基站或者无线局域网接入点相互通信是不现实的。Common communication devices (such as mobile phones) communicate with each other by means of cellular base stations or Wireless Local Area Networks (WLAN) access points, and access to cellular base stations or wireless local area networks when these mobile communication devices are relatively close. The communication points communicate with each other, which not only causes the communication cost to rise, but also increases the burden on the cellular base station or the wireless local area network access point. In addition, cellular base stations and wireless local area network access points are not always available. In remote areas without cellular network coverage or sudden spontaneous combustion disasters, it is unrealistic for mobile communication devices to communicate with each other via cellular base stations or wireless local area network access points. of.
当移动通信装置距离较近时，常采用WiFi直连或者Soft AP(Access Point，简称AP)的方式相互通信。WiFi直连是一种客户端到接入点的点对点(Peer to Peer，简称P2P)实现，一个P2P组包括一个P2P GO(Group Owner，简称GO)和一个或多个P2P Client，同一个P2P组中的P2P Client之间相互通信必须借助P2P GO。P2P组是以P2P GO为中心的，因此整个P2P组的通信范围受到P2P GO通信范围的限制。此外，不同的P2P组是不能相互融合的。当采用Soft AP的方式相互通信时，开启Soft AP的移动通信装置相当于无线局域网接入点，接入Soft AP的移动通信装置之间相互通信必须借助Soft AP，整个网络是以Soft AP为中心的，因此整个网络的通信范围受到开启Soft AP的移动通信装置的通信范围的限制。此外，不同的Soft AP网络是不能相互融合的。When the mobile communication device is close to each other, the WiFi direct connection or the Soft AP (Access Point, AP for short) is used to communicate with each other. A WiFi direct connection is a peer-to-peer (Peer-to-Peer) implementation of a client-to-access point. A P2P group includes a P2P GO (Group Owner, GO) and one or more P2P clients, and the same P2P group. The P2P Clients in the middle of each other must communicate with each other via P2P GO. The P2P group is centered on the P2P GO, so the communication range of the entire P2P group is limited by the P2P GO communication range. In addition, different P2P groups cannot be merged with each other. When the Soft AP is used to communicate with each other, the mobile communication device that starts the Soft AP is equivalent to the wireless LAN access point, and the mobile communication devices that access the Soft AP must communicate with each other via the Soft AP. The entire network is centered on the Soft AP. Therefore, the communication range of the entire network is limited by the communication range of the mobile communication device that opens the Soft AP. In addition, different Soft AP networks cannot be integrated with each other.
无线自组织网络是一种无中心的网络，采用无线自组织网络进行通信可以拓展网络的覆盖范围，无线自组织网络中的某个移动通信装置失效并不影响其它移动通信装置进行通信，无线自组织网络的健壮性强，此外，无线自组织网络还支持网络融合。申请号为201210251730.X的发明专利公开了一种基于Android手机的移动自组网系统及其构建方法，该系统主要包括多部Android手机和安装在手机上的WiFi网卡Ad-Hoc模式管理器、自动IP地址分配管理器和网络拓扑管理器，构建方法包括手机WiFi的Ad-Hoc模式的开启，网络中节点IP地址的自动分配和节点移动状态下网络拓扑的融合，该发明支持移动网络拓扑环境下Android手机IP地址自动分配并保证网络中每个手机节点IP地址的唯一性，但是该发明没有涉及移动自组网中的路由机制，此外该发明提出的IP地址分配方法复杂，当有新的手机节点加入网络或者发生网络融合时，IP地址分配过程耗时。The wireless self-organizing network is a non-central network. The wireless self-organizing network can communicate to expand the coverage of the network. The failure of a mobile communication device in the wireless self-organizing network does not affect the communication of other mobile communication devices. The organization network is robust, and wireless self-organizing networks also support network convergence. The invention patent No. 201210251730.X discloses a mobile ad hoc network system based on Android mobile phone and a construction method thereof, the system mainly comprises a plurality of Android mobile phones and a WiFi network card Ad-Hoc mode manager installed on the mobile phone, The automatic IP address allocation manager and the network topology manager are constructed by the activation of the Ad-Hoc mode of the mobile phone WiFi, the automatic allocation of the node IP address in the network, and the integration of the network topology in the node moving state. The invention supports the mobile network topology environment. The IP address of the Android mobile phone is automatically allocated and guarantees the uniqueness of the IP address of each mobile phone node in the network, but the invention does not involve the routing mechanism in the mobile ad hoc network, and the IP address allocation method proposed by the invention is complicated when there is a new When a mobile phone node joins the network or network convergence occurs, the IP address allocation process takes time.

Each of the communication devices needs to select one communication device from the adjacent one-hop communication device of the communication device as the next hop.

首先说明本发明的技术原理，本发明采用链路状态值综合描述本通信装置的下 一跳通信装置与本通信装置的数据收发子单元两个方面的因素，在多个本发明所述的基于无线自组织网络的移动通信装置形成的无线自组织网络中，每个移动通信装置周期性地产生链路状态报文并广播出去，上述每个移动通信装置周期性地产生并广播出去的链路状态报文的链路状态值为最大值，每个通信装置当接收到其它通信装置发送的链路状态报文(包括其它通信装置原始产生的链路状态报文和其它通信装置转发的链路状态报文)后计算并更新链路状态报文的链路状态值并将符合条件的更新后的链路状态报文以广播的形式转发出去，每个通信装置发送的链路状态报文(包括本通信装置原始产生的链路状态报文和本通信装置转发的链路状态报文)的链路状态值都表示本通信装置与目的通信装置(本通信装置发送的链路状态报文的原始发送方MAC地址对应的通信装置)之间的链路状态。First, the technical principle of the present invention will be described. The present invention comprehensively describes the underlying communication device by using link state values. Two factors of the one-hop communication device and the data transceiving subunit of the communication device, in the wireless ad hoc network formed by the plurality of wireless ad hoc network-based mobile communication devices according to the present invention, each mobile communication device cycle Generating a link state message and broadcasting it, the link state value of the link state message periodically generated and broadcast by each of the mobile communication devices is a maximum value, and each communication device receives another communication device. The link state message sent (including the link state message originally generated by other communication devices and the link state message forwarded by other communication devices) calculates and updates the link state value of the link state message and meets the condition The updated link state message is forwarded in the form of a broadcast, and the link state message sent by each communication device (including the link state message originally generated by the communication device and the link status report forwarded by the communication device) The link state value of the text indicates that the communication device corresponds to the destination communication device (the original sender MAC address of the link state message sent by the communication device) Link status between the communication device).
在上述计算链路状态报文的链路状态值的过程中综合考虑两个方面的因素，一方面为此链路状态报文的直接发送通信装置(直接发送通信装置也是本通信装置的相邻一跳通信装置，直接发送通信装置指发送此链路状态报文并且此链路状态报文被本通信装置直接接收的通信装置，直接发送通信装置发送的链路状态报文的来源包括两种情况，一种情况是直接发送通信装置产生的链路状态报文，另一种情况是直接发送通信装置转发的其它通信装置发送的链路状态报文)与目的通信装置(此链路状态报文的原始发送方MAC地址对应的通信装置)之间的链路状态，本通信装置接收到的链路状态报文的链路状态值即更新之前的链路状态报文的链路状态值可以表示此链路状态报文的直接发送通信装置与目的通信装置(此链路状态报文的原始发送方MAC地址对应的通信装置)之间的链路状态。另一方面为本通信装置与此链路状态报文的直接发送通信装置之间的链路状态；本通信装置综合考虑上述两个方面的因素计算出链路状态值。因此，本通信装置计算出的链路状态值可以用来表示在以此链路状态报文的原始发送方MAC地址对应的通信装置作为目的通信装置并且以此链路状态报文的直接发送通信装置为下一跳通信装置并且通过选定的本通信装置的数据收发子单元发送数据时本通信装置与目的通信装置(此链路状态报文的原始发送方MAC地址对应的通信装置)之间的链路状态，对于本通信装置而言，本通信装置若要向目的通信装置发送数据，需要从本通信装置的相邻一跳通信装置中选择一个相邻一跳通信装置作为下一跳，并且从本通信装置的数据收发子单元中选取一个数据收发子单元来发送数据，以确保本通信装置与目的通信装置之间的链路状态值最大，从而选择本通信装置与目的通信装置之间的最佳通信路径。In the above process of calculating the link state value of the link state message, two factors are comprehensively considered. On the one hand, the link state message directly transmits the communication device (the direct transmission communication device is also the neighbor of the communication device). A one-hop communication device, the direct transmission communication device refers to a communication device that transmits the link state message and the link state message is directly received by the communication device, and the source of the link state message directly sent by the communication device includes two types. In one case, one case is to directly transmit a link state message generated by the communication device, and the other case is to directly send a link state message sent by another communication device forwarded by the communication device) and the destination communication device (the link state report) The link state between the communication device corresponding to the original sender MAC address of the text, the link state value of the link state message received by the communication device, that is, the link state value of the link state message before the update may be a direct transmission communication device indicating the link state message and a destination communication device (a communication device corresponding to the original sender MAC address of the link state message) The link status. On the other hand, the communication state is the link state between the communication device and the direct transmission communication device of the link state message; the communication device calculates the link state value by considering the above two factors. Therefore, the link state value calculated by the communication device can be used to indicate that the communication device corresponding to the original sender MAC address of the link state message is used as the destination communication device and the direct transmission communication of the link state message is When the device is a next hop communication device and transmits data through the selected data transceiving subunit of the communication device, the communication device is in communication with the destination communication device (the communication device corresponding to the original sender MAC address of the link state message) Link status, for the communication device, if the communication device is to send data to the destination communication device, it is necessary to select a neighboring one-hop communication device as the next hop from the adjacent one-hop communication device of the communication device. And selecting a data transceiver subunit from the data transceiver subunit of the communication device to transmit data to ensure that the link state value between the communication device and the destination communication device is the largest, thereby selecting between the communication device and the destination communication device. The best communication path.
本通信装置将计算后的链路状态值更新到链路状态报文中并将符合条件的更新后的链路状态报文以广播的形式转发出去，这样，当本通信装置的相邻一跳通信装置接收到本通信装置发送的链路状态报文后，可以用本通信装置发送的链路状态报文的链路状态值表示本通信装置与目的通信装置(本通信装置发送的链路状态报文的原始发送方MAC地址对应的通信装置)之间的链路状态，本通信装置的相邻一跳通信装置可以计算出本通信装置的相邻一跳通信装置与本通信装置之间的链路状态，进而，本通信装置的相邻一跳通信装置可以计算出其与目的通信装置(本通信装置发送的链路状态报文的原始发送方MAC地址对应的通信装置)之间的链路状态。The communication device updates the calculated link state value to the link state message and forwards the qualified updated link state message in a broadcast manner, so that when the communication device is adjacent to the hop After receiving the link state message sent by the communication device, the communication device may use the link state value of the link state message sent by the communication device to indicate the communication device and the destination communication device (the link state sent by the communication device) The link state between the communication device corresponding to the original sender MAC address of the message, the adjacent one-hop communication device of the communication device can calculate the relationship between the adjacent one-hop communication device of the communication device and the communication device Link state, and further, the adjacent one-hop communication device of the communication device can calculate a chain between the communication device and the destination communication device (the communication device corresponding to the original sender MAC address of the link state message transmitted by the communication device) Road status.

In addition, the routing information maintained by the routing unit 12 is also based on the MAC address of the destination communication device, so the data parsing unit 11 includes the ARP subunit 22. The ARP sub-unit 22 maintains the correspondence between the IP address and the MAC address based on the ARP (Address Resolution Protocol), and sends and receives the ARP packet for maintaining the correspondence between the IP address and the MAC address by using the data transceiving unit 13 (Slightly omitted), this is an address resolution process well known in the art and will not be described in detail herein. The data encapsulation subunit 21 receives the IP data packet generated by the communication device that the communication device needs to transmit, extracts the IP address of the receiver in the IP data packet, and sends the query information including the IP address of the receiver to the ARP subunit 22, the ARP sub- The unit 22 transmits query response information including the recipient MAC address corresponding to the recipient IP address in the query information to the data encapsulation subunit 21, and the data encapsulation subunit 21 sends a route query request to the routing unit 12 based on the receiver MAC address, and routes The query request includes a recipient MAC address corresponding to the recipient IP address of the IP packet and a MAC address of the data transceiver subunit of the received load data frame in the communication device, and the communication device needs to transmit the IP generated by the communication device. In the case of a data packet, the data transceiver sub-unit MAC address of the received load data frame in the route query request is empty, and the communication device needs to transmit an IP data packet generated by the non-local communication device (ie, the communication device is used as a multi-hop path) Receiving load in a routing query request in the case where one hop forwards an IP packet generated by another communication device) The data transceiving subunit MAC address of the data frame is not empty, which is the MAC address of the data transceiving subunit that actually receives the payload data frame in the communication device. Therefore, for the load data frame, the routing unit 12 sends a route query response to the data encapsulation sub-unit 21 according to the route query request, where the route query response includes the MAC address of the adjacent one-hop communication device selected by the communication device and the data transmission and reception in the communication device.

The receiver MAC address of the above-configured load data frame is the MAC address of the adjacent one-hop communication device in the route query response, and the above-described load data frame is constructed. The sender MAC address is the MAC address of the data transceiving subunit in the routing query response, and the frame body of the payload data frame constructed above is the payload data tag and the above IP packet. Preferably, in the frame body of the payload data frame configured as described above, in addition to the payload data tag and the IP data packet, the receiver MAC address entry corresponding to the recipient IP address of the IP data packet may be selectively included. If the frame body of the load data frame configured as described above includes the receiver MAC address entry corresponding to the IP address of the receiver of the IP data packet, the other device on the multi-hop transmission path receives the load data frame and extracts the load data frame. The receiver MAC address entry corresponding to the IP packet receiver IP address included in the frame body can determine the MAC address of the communication device that finally receives the IP packet in the frame body, and the frame body of the payload data frame constructed as described above Excluding the receiver MAC address entry corresponding to the recipient IP address of the IP packet, the other device on the multi-hop transmission path receives the payload data frame and extracts the receiver IP of the IP packet in the frame body of the payload data frame. The address can then also determine the MAC address of the communication device that ultimately receives the IP packet in the frame body by means of the ARP subunit. The solution of the present invention is described below in the general payload data frame structure (excluding the recipient MAC address entry corresponding to the recipient IP address of the IP packet). The data encapsulation sub-unit 21 transmits the load data frame constructed as described above to the data transceiving sub-unit corresponding to the MAC address of the data transceiving sub-unit in the routing query response and transmits it by the data transceiving sub-unit. The routing unit in the present invention maintains the optimal next hop communication device of the communication device, based on the MAC address of the adjacent one hop communication device included in the route query response and the MAC address of the data transceiver subunit in the communication device. The load data frame ensures that the payload data frame communicates with the destination communication device in accordance with the optimal communication path.

The pre-processing module 51 receives the routing data information sent from the data parsing unit 11, the routing data information including the routing data frame and the MAC address of the data transceiving sub-unit receiving the routing data frame, and the pre-processing module 51 transmits the valid to the trans-transmitting information storage module 52. Determining the request, the valid determination request includes a receiving time, an original sender MAC address of the link state message of the routing data frame, and a sequence number of the link state message of the routing data frame, where the receiving time is received by the preprocessing module 51 The transmission/reception information storage module 52 transmits a determination response to the pre-processing module 51 based on the valid determination request to the system time when the data information is routed, and the determination response is classified into two types: a valid determination response and an invalidation response.
收发信息存储模块52维护第一绑定表，第一绑定表记录原始发送方MAC地址、序列号和最新接收时间，收发信息存储模块52基于预处理模块51发送的有效判定请求来维护第一绑定表。收发信息存储模块52在第一绑定表中查找原始发送方MAC地址为有效判定请求中路由数据帧的链路状态报文的原始发送方MAC地址的表项，若没有查找到对应的表项，说明上述路由数据信息是最新的，则在表中新增一项记录并向预处理模块51发送有效判定应答，上述新增记录的原始发送方MAC地址、序列号和最新接收时间分别为有效判定请求中的原始发送方MAC地址、序列号和接收时间；收发信息存储模块52若在第一绑定表中查找到原始发送方MAC地址为有效判定请求中的原始发送方MAC地址的表项，则比较上述表项的序列号 与有效判定请求中的序列号的大小关系，若上述表项的序列号小于有效判定请求中的序列号，说明上述路由数据信息是最新的，因为如之前所述的针对每个数据收发子单元每次新产生原始路由数据帧时其中的序列号增加1，则将上述表项中的序列号和最新接收时间更新为有效判定请求中的序列号和接收时间，并向预处理模块51发送有效判定应答，若上述表项的序列号大于或者等于有效判定请求中的序列号，说明上述路由数据信息不是最新的，则向预处理模块51发送无效判定应答。The transceiver information storage module 52 maintains a first binding table, the first binding table records the original sender MAC address, the serial number, and the latest receiving time, and the transceiver information storage module 52 maintains the first based on the valid determination request sent by the preprocessing module 51. Bind the table. The transceiver information storage module 52 searches the first binding table for the entry of the original sender MAC address of the link state packet of the routing data frame in the original determination sender MAC address, if no corresponding entry is found. If the routing data information is the latest, a new record is added to the table and a valid decision response is sent to the pre-processing module 51. The original sender MAC address, serial number, and latest receiving time of the newly added record are respectively valid. Determining the original sender MAC address, the sequence number, and the receiving time in the request; the transceiver information storage module 52 finds an entry in the first binding table that the original sender MAC address is the original sender MAC address in the valid determination request. , compare the serial number of the above entry If the sequence number of the entry is smaller than the sequence number in the valid decision request, the routing data information is the latest because the sub-unit for each data is as described above. Each time the sequence number of the original routing data frame is newly increased, the sequence number and the latest receiving time in the above entry are updated to the serial number and the receiving time in the valid determination request, and are sent to the preprocessing module 51. If the sequence number of the entry is greater than or equal to the sequence number in the valid determination request, and the routing data information is not up-to-date, the invalidation response is sent to the pre-processing module 51.
在本通信装置具有一个数据收发子单元时，若预处理模块51从收发信息存储模块52接收到无效判定应答，则将路由数据信息丢弃，预处理过程结束，若预处理模块51从收发信息存储模块52接收到有效判定应答，则将路由数据信息发送至链路状态计算模块53；在本通信装置具有至少两个数据收发子单元时，若预处理模块51从收发信息存储模块52接收到无效判定应答，则将路由数据信息丢弃，预处理过程结束，若预处理模块51从收发信息存储模块52接收到有效判定应答，预处理模块51还需要进一步判断路由数据信息中的路由数据帧的发送方MAC地址是否为本通信装置的数据收发单元13的任一数据收发子单元的MAC地址，若路由数据信息中的路由数据帧的发送方MAC地址为本通信装置的数据收发单元13的任一数据收发子单元的MAC地址，表明上述路由数据信息中的路由数据帧是本通信装置发出同时被本通信装置自身接收的，这种情况下说明该路由数据帧不涉及本通信装置与其他通信装置间的通信过程，其不会提供反应本通信装置与其他通信装置间通信状态的信息，无需对其做进一步处理，直接将此路由数据信息丢弃，预处理过程结束；若路由数据信息中的路由数据帧的发送方MAC地址不为本通信装置的数据收发单元13的任一数据收发子单元的MAC地址，表明上述路由数据信息中的路由数据帧不是本通信装置发出的，则将路由数据信息发送至链路状态计算模块53，这样本通信装置接收到的其他通信装置发送来的所有最新路由数据信息中的路由数据帧的链路状态报文中的原始发送方MAC地址、链路状态报文中的序列号和最新接收时间都由收发信息存储模块52记录在第一绑定表中，同时这些最新的路由数据信息经预处理模块发送至链路状态计算模块53。When the communication device has a data transceiving subunit, if the preprocessing module 51 receives the invalidation response from the transceiving information storage module 52, the routing data information is discarded, and the preprocessing process ends, if the preprocessing module 51 is configured to receive and receive information. When the module 52 receives the valid decision response, the routing data information is sent to the link state calculation module 53. If the communication device has at least two data transceiver subunits, if the preprocessing module 51 receives the invalid from the transceiver information storage module 52 If the response is determined, the routing data information is discarded, and the preprocessing process ends. If the preprocessing module 51 receives the valid decision response from the transceiver information storage module 52, the preprocessing module 51 further needs to determine the transmission of the routing data frame in the routing data information. Whether the party MAC address is the MAC address of any data transceiving subunit of the data transceiving unit 13 of the communication device, and if the sender MAC address of the routing data frame in the routing data information is any of the data transceiving units 13 of the communication device The MAC address of the data transceiver subunit indicates the number of routes in the routing data information. The frame is sent by the communication device and received by the communication device itself. In this case, the routing data frame does not involve the communication process between the communication device and other communication devices, and does not provide a response to the communication device and other communication devices. The information of the communication status does not need to be further processed, and the routing data information is directly discarded, and the preprocessing process ends; if the sender MAC address of the routing data frame in the routing data information is not the data transceiving unit 13 of the communication device The MAC address of any data transceiver subunit indicates that the routing data frame in the routing data information is not sent by the communication device, and the routing data information is sent to the link state calculation module 53, so that the communication device receives the other The original sender MAC address, the sequence number in the link state message, and the latest reception time in the link state message of the route data frame in all the latest route data information sent by the communication device are recorded by the transceiver information storage module 52. In the first binding table, the latest routing data information is sent through the pre-processing module. Calculation module 53 to the link state.
链路状态计算模块53根据路由数据信息计算链路状态值，本通信装置的相邻一跳通信装置与目的通信装置之间的链路状态用路由数据信息中的路由数据帧的链路状态报文的链路状态值表示，因此，本通信装置需要计算本通信装置与相邻一跳通信装置之间的链路状态，相对于本通信装置而言，本通信装置与本通信装置的相邻一跳通信装置之间的链路可以分为发送链路和接收链路，在本发明中，本通信装置与本通信装置的相邻一跳通信装置之间的链路状态指的是上述发送链路的链路状态；本发明采用本通信装置发送的数据被本通信装置的相邻一跳通信装置成功接收(直接或间接)并且被本通信装置的相邻一跳通信装置转发并且又被本通信装置成功接收的概率来表示本通信装置与本通信装置的相邻一跳通信装置之间的发送链路状态与接收链路状态的叠加值。具体的可以采用本通信装置发送的本通信装置产生的原始路由数据帧的链路状态报文被本通信装置的相邻一跳通信装置成功接收并且被本通信装置的相邻一跳通信装置转发并且又被本通信装置成功接收的概率来表示本通信装置与本通信装置的相邻一跳通信装置之间的发送链路状态与接收链路状态的叠加值，也可以采用本通信装置发送的其它通信装置产生的链路状态报文被本通信装置的相邻一跳通信装置成功接收并且被本通信装置的相邻一跳通信装置转发并且又被本通信装置成功接收的概率来表示本通信装置与本通信装置的相邻一跳通信装置之间的发送链路状态与接收链路状态的叠加值。优选的，采用本通信装置发送 的本通信装置原始产生的链路状态报文被本通信装置的相邻一跳通信装置成功接收并且被本通信装置的相邻一跳通信装置转发并且又被本通信装置成功接收的概率来表示本通信装置与本通信装置的相邻一跳通信装置之间的发送链路状态与接收链路状态的叠加值，以下阐述本发明原理的内容采用的是上述优选的方法。本发明采用本通信装置的相邻一跳通信装置发送的数据被本通信装置成功接收的概率来表示本通信装置与本通信装置的相邻一跳通信装置之间的接收链路状态的接收值，具体的可以采用本通信装置的相邻一跳通信装置发送的路由数据帧的链路状态报文(包括本通信装置的相邻一跳通信装置原始产生的路由数据帧的链路状态报文和其转发的其它通信装置原始产生的路由数据帧的链路状态报文)被本通信装置成功接收的概率来表示本通信装置与本通信装置的相邻一跳通信装置之间的接收链路状态的接收值，优选的采用本通信装置的相邻一跳通信装置发送的非本通信装置原始产生的链路状态报文被本通信装置成功接收的概率来表示本通信装置与本通信装置的相邻一跳通信装置之间的接收链路状态的接收值。因无法直接计算本通信装置与本通信装置的相邻一跳通信装置之间的发送链路状态，因此本发明采用间接计算的方法，首先本发明计算本通信装置发送的数据(优选原始路由数据帧的链路状态报文)被本通信装置的相邻一跳通信装置成功接收并且被本通信装置的相邻一跳通信装置转发并且又被本通信装置成功接收的叠加概率，用以表示本通信装置与本通信装置的相邻一跳通信装置之间的发送链路状态与接收链路状态的叠加值，这种叠加概率可表示为Y＝P1*P2，其中P1表示本通信装置发送的数据被本通信装置的相邻一跳通信装置成功接收的本通信装置的成功发送概率，P2表示本通信装置的相邻一跳通信装置发送的数据被本通信装置成功接收的本通信装置的成功接收概率。因此上述叠加概率即可反应本通信装置与本通信装置的相邻一跳通信装置之间的发送链路状态与接收链路状态。进一步的本发明计算本通信装置的相邻一跳通信装置发送的数据(不一定转发本通信装置发送的数据)被本通信装置成功接收的本通信装置的成功接收概率P2′，用以表示本通信装置与本通信装置的相邻一跳通信装置之间的接收链路状态的接收值。最后基于上述叠加概率和成功接收概率计算得到本通信装置发送的数据被本通信装置的相邻一跳通信装置成功接收的本通信装置的成功发送概率：(P1*P2)/P2′，这种成功发送概率可以反应本通信装置与本通信装置的相邻一跳通信装置之间的发送链路状态，成功发送概率高的相邻一跳通信装置将作为本通信装置发送数据时择优选择的下一跳的通信装置。下面将具体描述这一原理过程的创新实现方案。The link state calculation module 53 calculates the link state value according to the route data information, and the link state report of the route data frame in the route state information of the link state between the adjacent one-hop communication device and the destination communication device of the communication device The link state value of the text indicates that, therefore, the communication device needs to calculate the link state between the communication device and the adjacent one-hop communication device, and the communication device is adjacent to the communication device with respect to the communication device. The link between the one-hop communication devices can be divided into a transmission link and a reception link. In the present invention, the link state between the communication device and the adjacent one-hop communication device of the communication device refers to the above transmission. Link state of the link; the data transmitted by the communication device of the present invention is successfully received (directly or indirectly) by the adjacent one-hop communication device of the communication device and forwarded by the adjacent one-hop communication device of the communication device and is again The probability of successful reception by the communication device indicates the superimposed value of the transmission link state and the reception link state between the communication device and the adjacent one-hop communication device of the communication device. Specifically, the link state message of the original routing data frame generated by the communication device that can be sent by the communication device is successfully received by the adjacent one-hop communication device of the communication device and forwarded by the adjacent one-hop communication device of the communication device. And the probability of successful reception by the communication device indicates the superposition value of the transmission link state and the reception link state between the communication device and the adjacent one-hop communication device of the communication device, and may also be sent by the communication device. The link status message generated by the other communication device is successfully received by the adjacent one-hop communication device of the communication device and is forwarded by the adjacent one-hop communication device of the communication device and is again successfully received by the communication device to indicate the communication. The superimposed value of the transmit link state and the receive link state between the device and the adjacent one-hop communication device of the present communication device. Preferably, the communication device is used for sending The link state message originally generated by the communication device is successfully received by the adjacent one-hop communication device of the communication device and is forwarded by the adjacent one-hop communication device of the communication device and is further represented by the probability that the communication device successfully receives the communication device. The superimposed values of the transmit link state and the receive link state between the present communication device and the adjacent one-hop communication device of the present communication device, which are described below in the context of the principles of the present invention. The present invention uses the probability that the data transmitted by the adjacent one-hop communication device of the communication device is successfully received by the communication device to indicate the reception value of the receiving link state between the communication device and the adjacent one-hop communication device of the communication device. Specifically, the link state message of the routing data frame sent by the adjacent one-hop communication device of the communication device (including the link state message of the routing data frame originally generated by the adjacent one-hop communication device of the communication device) The link state message of the routing data frame originally generated by the other communication device forwarded by the other communication device is successfully received by the communication device to indicate the receiving link between the communication device and the adjacent one-hop communication device of the communication device The received value of the state, preferably the probability that the link state message originally generated by the non-local communication device transmitted by the adjacent one-hop communication device of the communication device is successfully received by the communication device indicates the communication device and the communication device Received value of the receive link state between adjacent one-hop communication devices. Since the transmission link state between the communication device and the adjacent one-hop communication device of the communication device cannot be directly calculated, the present invention adopts an indirect calculation method. First, the present invention calculates data transmitted by the communication device (preferably original routing data). The link state message of the frame) is successfully received by the adjacent one-hop communication device of the communication device and is forwarded by the adjacent one-hop communication device of the communication device and is successfully received by the communication device to indicate the present a superposition value of a transmission link state and a reception link state between the communication device and the adjacent one-hop communication device of the communication device, the superposition probability may be expressed as Y=P1*P2, where P1 represents the transmission by the communication device The successful transmission probability of the communication device successfully received by the adjacent one-hop communication device of the communication device, and P2 indicates the success of the communication device successfully received by the communication device by the adjacent one-hop communication device of the communication device. Receive probability. Therefore, the above superposition probability can reflect the transmission link state and the reception link state between the communication device and the adjacent one-hop communication device of the communication device. Further, the present invention calculates the successful reception probability P2' of the communication device successfully received by the communication device by the data transmitted by the adjacent one-hop communication device of the communication device (not necessarily forwarding the data transmitted by the communication device), and is used to indicate the present The received value of the receive link state between the communication device and the adjacent one-hop communication device of the present communication device. Finally, based on the superposition probability and the successful reception probability, the successful transmission probability of the communication device successfully received by the adjacent one-hop communication device of the communication device by the communication device is calculated: (P1*P2)/P2'. The probability of successful transmission may reflect the status of the transmission link between the communication device and the adjacent one-hop communication device of the communication device, and the adjacent one-hop communication device with a high probability of successful transmission will be selected as the preferred selection when transmitting the data by the communication device. One-hop communication device. An innovative implementation of this principle process will be described in detail below.
链路状态计算模块53维护第二绑定表，第二绑定表用来记录上述叠加值的对应关系，第二绑定表的表项包括数据收发子单元MAC地址、候选路由MAC地址、叠加值，对于表中的每一项记录都维护一个叠加队列，第二绑定表中的每项记录对应的叠加队列长度相同，叠加队列中存储链路状态报文的序列号，用叠加队列中序列号的数量与叠加队列长度的比值反应本通信装置发送的数据被本通信装置的相邻一跳通信装置成功接收并且被本通信装置的相邻一跳通信装置转发并且又被本通信装置成功接收的叠加概率，叠加队列中序列号的数量与叠加队列长度的比值即为对应表项的叠加值，第二绑定表中的数据收发子单元MAC地址相同的表项对应的叠加队列的序列号移入、移出过程保持同步，叠加队列中的元素移入、移出叠加队列按照先入先出的原则。The link state calculation module 53 maintains a second binding table, where the second binding table is used to record the correspondence between the superposition values, and the entries of the second binding table include a data transceiver sub-unit MAC address, a candidate routing MAC address, and an overlay. The value maintains an overlay queue for each record in the table. The length of the overlay queue corresponding to each record in the second binding table is the same. The sequence number of the link state message is stored in the overlay queue. The ratio of the number of serial numbers to the length of the superimposed queue reflects that the data transmitted by the communication device is successfully received by the adjacent one-hop communication device of the communication device and is forwarded by the adjacent one-hop communication device of the communication device and is successfully succeeded by the communication device. The superimposed probability of the received, the ratio of the number of the serial number in the superimposed queue to the length of the superimposed queue is the superimposed value of the corresponding entry, and the sequence of the superimposed queue corresponding to the entry with the same MAC address of the data transceiving subunit in the second binding table The number shifting in and out process is kept in sync, and the elements in the stacking queue are moved in and out of the stacking queue according to the principle of first in, first out.
链路状态计算模块53维护第三绑定表，第三绑定表用来记录上述接收值的对应关系，第三绑定表的表项包括目的MAC地址、数据收发子单元MAC地址、候选路 由MAC地址、接收值和最新接收时间，对于表中的每项记录都维护一个接收队列，第三绑定表中的每项记录对应的接收队列的长度相同，且优选的所述接收队列与上述叠加队列的长度相同，接收队列中存储链路状态报文的序列号，将接收队列中序列号的数量与接收队列长度的比值作为本通信装置的相邻一跳通信装置发送的数据被本通信装置成功接收的概率，接收队列中序列号的数量与接收队列长度的比值即为对应表项的接收值，第三绑定表中的目的MAC地址相同并且数据收发子单元MAC地址相同的表项对应的接收队列的序列号移入、移出过程保持同步，接收队列中的元素移入、移出叠加队列按照先入先出的原则。The link state calculation module 53 maintains a third binding table, where the third binding table is used to record the correspondence between the received values, and the entries of the third binding table include a destination MAC address, a data transceiver sub-unit MAC address, and a candidate path. A receiving queue is maintained for each record in the table by the MAC address, the received value, and the latest receiving time. The length of the receiving queue corresponding to each record in the third binding table is the same, and the preferred receiving queue is The length of the superimposed queue is the same, and the sequence number of the link state message is stored in the receiving queue, and the ratio of the number of the serial number in the receiving queue to the length of the receiving queue is used as the data sent by the adjacent one-hop communication device of the communication device. The probability that the communication device successfully receives, the ratio of the number of the sequence number in the receiving queue to the length of the receiving queue is the received value of the corresponding entry, and the table in the third binding table has the same destination MAC address and the same MAC address of the data transceiver subunit The sequence number of the receiving queue corresponding to the item is kept in synchronization with the process of moving in and out, and the elements in the receiving queue are moved in and out of the stacking queue according to the principle of first in first out.
链路状态计算模块53接收预处理模块51发送的路由数据信息，路由数据信息包括路由数据帧和接收此路由数据帧的数据收发子单元的MAC地址，若路由数据帧的链路状态报文的原始发送方MAC地址为本通信装置的任一数据收发子单元的MAC地址，表明此链路状态报文为本通信装置产生并且此链路状态报文被本通信装置的相邻一跳通信装置成功接收后被该相邻一跳通信装置转发并且又被本通信装置成功接收，则更新第二绑定表。在本通信装置只具有一个数据收发子单元时，本通信装置原始产生的链路状态报文必然通过本通信装置唯一的数据收发子单元发送，上述链路状态报文被本通信装置的相邻一跳通信装置接收并转发后若被本通信装置接收则必然被本通信装置唯一的数据收发子单元接收。在本通信装置具有多个数据收发子单元时，存在本通信装置原始产生的链路状态报文被本通信装置的某一数据收发子单元发送但是上述链路状态报文经本通信装置的相邻一跳通信装置接收并转发后被本通信装置的另一数据收发子单元接收的情况，上述情况也属于本通信装置发送的数据被本通信装置的相邻一跳通信装置接收并转发并且又被本通信装置接收的范围，所以本发明在计算第二绑定表中的叠加值时，将上述情况近似为本通信装置的相邻一跳通信装置转发的本通信装置原始产生的链路状态报文被本通信装置的相同的数据收发子单元(本通信装置发送上述本通信装置原始产生的链路状态报文的数据收发子单元)接收，这种近似并不影响最终链路状态值的计算。具体的，链路状态计算模块53在第二绑定表中查找数据收发子单元MAC地址为路由数据信息的路由数据帧的链路状态报文的原始发送方MAC地址(本通信装置中的数据收发子单元的MAC地址)并且候选路由MAC地址为路由数据信息的路由数据帧的发送方MAC地址的表项，若不能在第二绑定表中查找到上述表项，则在第二绑定表中新增一项记录，上述新增记录的数据收发子单元MAC地址为路由数据信息的路由数据帧的链路状态报文的原始发送方MAC地址，上述新增记录的候选路由MAC地址为路由数据信息的路由数据帧的发送方MAC地址，新增记录后进行如下表项更新过程；若能在第二绑定表中查找到上述表项，则直接进行如下表项更新过程：设第二绑定表中数据收发子单元MAC地址为路由数据信息的路由数据帧的链路状态报文的原始发送方MAC地址的表项对应的叠加队列中的序列号的最大值为a，设链路状态计算模块53接收到的路由数据信息中的链路状态报文的序列号为b(b必然大于a，因为链路状态计算模块53接收到的路由数据信息中的路由数据帧必然为最新产生的，其中链路状态报文中的序列号会在原来基础上(包括0)递增1，若b小于或者等于a，收发信息存储模块52会向预处理模块51发送无效判定应答，预处理模块51收到无效判定应答后会将路由数据信息丢弃，不会到达链路状态计算模块53)，称在第二绑定表中数据收发子单元MAC地址为路由数据信息的路由数据帧的链路状态报文的原始发送方MAC地址并且候选路由MAC地址为路由数据信息的路由数据帧的发送方MAC地址的表项为本叠加表项，则向第二绑定表中数据收发子 单元MAC地址为路由数据信息的路由数据帧的链路状态报文的原始发送方MAC地址的表项中除本叠加表项以外的其它表项的叠加队列中依次移入(b-a)个空元素，向本叠加表项的叠加队列中依次移入(b-a-1)个空元素和序列号b，计算并更新第二绑定表中数据收发子单元MAC地址为路由数据信息的路由数据帧的链路状态报文的原始发送方MAC地址的表项的叠加值，叠加值为对应叠加队列中序列号的数量与叠加队列长度的比值，这样，通过向第二绑定表中的表项对应的叠加队列中移入序列号或者空元素，基于叠加队列的先入先出的特性，叠加值可以动态地表示出本通信装置与本通信装置的各个相邻一跳通信装置的发送链路状态与接收链路状态的叠加概率。在此对该技术原理进行详细的解释，如上所述第二绑定表中每一个表项记录有数据收发子单元MAC地址、候选路由MAC地址和叠加值的对应关系，而且第二绑定表的更新仅限于本通信装置接收的路由数据信息的路由数据帧的链路状态报文的原始发送方MAC地址为本通信装置的任一数据收发子单元的MAC地址，也就是说第二绑定表实际上记录了本通信装置产生的原始路由数据帧中的链路状态报文被本通信装置的相邻一跳通信装置接收并转发给本通信装置的发送链路和接收链路的通信情况，而且因为本通信装置每次新产生一个原始路由数据帧其链路状态报文中的序列号都会在原有基础上增加1，这样对应于本通信装置每个新产生的原始路由数据帧中的链路状态报文被其相邻一跳通信装置转发回来的情况都会被链路状态计算模块53自动更新在上述第二绑定表中，且所述第二绑定表中的一个数据收发子单元MAC地址可对应于多个表项，因为一个数据收发子单元发出的原始路由数据帧中的链路状态报文可能会被多个相邻一条通信装置接收并转发回本通信装置，从而一个数据收发子单元MAC地址可对应有多个候选MAC地址，为了在这多个候选MAC地址中选择最优的候选MAC地址，本发明在上述更新中，每次向本叠加表项对应的叠加队列补入序列号，同时将其他表项对应的叠加队列补空(避免了叠加队列一直保持之前的序列号数量不变，保证了与所述本叠加表项处于同等的动态更新过程)，在预定时间段内补入序列号最多的那个叠加队列所对应表项中的候选MAC所对应的通信装置应当是该段时间内接收本通信装置发出的原始路由数据帧的链路状态报文并向本通信装置转发所述原始路由数据帧的链路状态报文次数最多的通信装置，也就是说MAC地址与所述候选MAC地址(补入序列号最多的叠加队列所对应表项中的候选MAC)相同的通信装置在该段时间内与本通信装置的来回通信较为频繁，其相互之间的通信链路状态较佳，可作为本通信装置优选的下一跳通信装置。所以上述叠加值能够反应本通信装置与本通信装置的相邻一跳通信装置之间成功发送通信和成功接收通信的叠加概率。为了计算这种叠加概率本发明首创的引入上述叠加队列，如上所述预定时间段内链路状态计算模块53接收到的用于更新第二绑定表的路由数据信息越多，说明路由数据信息中路由数据帧的发送方MAC地址所在通信装置与本通信装置间的通信越频繁，又因为每个新的路由数据信息都包括有一个新的序列号，因此预定时间段内更新的序列号的数量即可代表上述通信频繁程度，为进一步将这种序列号的更新数量转换为一种概率，引入所述叠加队列，利用补入叠加队列中的序列号的数量与叠加队列长度的比值来作为概率，即所述的叠加值，其能够有效的反应本通信装置与本通信装置的各个相邻一跳通信装置间的发送链路状态与接收链路状态的叠加概率，下面的接收队列以及接收值基于同样的原理考虑，但本发明关于各概率的计算并不以此为限，引入队列只是其中一种优选方式，亦可采用其他的概率统计方法如预定时间段内成功通信次数与总通信请求次数的比值等，下同。 The link state calculation module 53 receives the routing data information sent by the preprocessing module 51. The routing data information includes a routing data frame and a MAC address of the data transceiver subunit that receives the routing data frame, and if the link state message of the routing data frame is The original sender MAC address is the MAC address of any data transceiver subunit of the communication device, indicating that the link state message is generated by the communication device and the link state message is used by the adjacent one hop communication device of the communication device. After being successfully received and forwarded by the adjacent one-hop communication device and successfully received by the communication device, the second binding table is updated. When the communication device has only one data transceiving subunit, the link state message originally generated by the communication device is necessarily transmitted by the unique data transceiving subunit of the communication device, and the link state message is adjacent to the communication device. After being received and forwarded by the one-hop communication device, if it is received by the communication device, it is necessarily received by the data transceiving subunit unique to the communication device. When the communication device has a plurality of data transceiving subunits, the link state message originally generated by the communication device is transmitted by a certain data transceiving subunit of the communication device, but the link state message passes through the phase of the communication device. When the adjacent-hop communication device receives and forwards and is received by another data transceiving sub-unit of the communication device, the above-mentioned case also belongs to the data transmitted by the communication device being received and forwarded by the adjacent one-hop communication device of the communication device and The range received by the communication device, so the present invention approximates the link state originally generated by the communication device forwarded by the adjacent one-hop communication device of the communication device when calculating the superimposed value in the second binding table. The message is received by the same data transceiving subunit of the communication device (the communication device transmits the data transceiving subunit of the link state message originally generated by the communication device), and the approximation does not affect the final link state value. Calculation. Specifically, the link state calculation module 53 searches the second binding table for the original sender MAC address of the link state message of the routing data frame whose data transceiver subunit MAC address is the routing data information (data in the communication device) The MAC address of the transceiver unit is transmitted, and the candidate routing MAC address is an entry of the sender MAC address of the routing data frame of the routing data information. If the entry cannot be found in the second binding table, the second binding is performed. A new record is added to the table, and the MAC address of the data transmission and reception subunit of the newly added record is the original sender MAC address of the link state message of the route data frame of the route data information, and the candidate route MAC address of the newly added record is The sender MAC address of the routing data frame of the routing data information is added to the following table item update process. If the above entry is found in the second binding table, the following table item update process is directly performed: The MAC address of the data transceiver subunit in the binding table is the sequence in the superposition queue corresponding to the original sender MAC address of the link state packet of the routing data frame of the routing data information. The maximum value of the column number is a, and the sequence number of the link state message in the route data information received by the link state calculation module 53 is b (b is necessarily greater than a because the route received by the link state calculation module 53) The routing data frame in the data information must be newly generated. The sequence number in the link state message is incremented by 1 on the original basis (including 0). If b is less than or equal to a, the transceiver information storage module 52 will advance to The processing module 51 sends an invalidation decision response, and the pre-processing module 51 discards the routing data information after receiving the invalidation decision response, and does not reach the link state calculation module 53), and refers to the data transceiver sub-unit MAC address in the second binding table. For the original sender MAC address of the link state message of the routing data frame of the routing data information and the entry MAC address of the routing data frame of the routing data information of the candidate routing MAC address is the superimposed entry, the Data binding in the second binding table The unit MAC address is a route element of the original sender MAC address of the link state packet of the routing data message, and the (KB) empty element is sequentially moved into the superposition queue of the entry other than the superimposed entry. The (ba-1) empty element and the sequence number b are sequentially moved into the superposition queue of the superposition table item, and the link of the routing data frame in which the MAC address of the data transceiving subunit in the second binding table is the routing data information is calculated and updated. The superimposed value of the entry of the original sender MAC address of the status message, and the superimposed value is the ratio of the number of the sequence number in the corresponding superposition queue to the length of the superimposed queue, so that the superposition corresponding to the entry in the second binding table is The sequence number or the empty element is moved into the queue. Based on the first-in first-out characteristics of the overlay queue, the superimposed value can dynamically indicate the transmission link status and the receiving link of each adjacent one-hop communication device of the communication device and the communication device. The probability of superposition of the state. The technical principle is explained in detail here. As described above, each entry in the second binding table records the correspondence between the data transceiver sub-unit MAC address, the candidate routing MAC address, and the superimposed value, and the second binding table. The update is limited to the routing message data received by the communication device. The original sender MAC address of the link state message of the routing data frame is the MAC address of any data transceiving subunit of the communication device, that is, the second binding. The table actually records the communication status of the transmission link and the receiving link that the link state message in the original routing data frame generated by the communication device is received by the adjacent one-hop communication device of the communication device and forwarded to the communication device. And because the communication device newly generates a raw routing data frame each time, the serial number in the link state message is increased by 1 on the original basis, corresponding to each newly generated original routing data frame of the communication device. The link state message is forwarded back by its neighboring one-hop communication device, and is automatically updated by the link state calculation module 53 in the second binding table, and The data transceiver sub-unit MAC address in the second binding table may correspond to multiple entries, because the link state message in the original routing data frame sent by one data transceiver sub-unit may be multiple adjacent ones. The communication device receives and forwards back to the local communication device, such that a data transceiving subunit MAC address can correspond to a plurality of candidate MAC addresses. In order to select an optimal candidate MAC address among the plurality of candidate MAC addresses, the present invention is in the above update. Each time, the serial number is added to the superimposed queue corresponding to the superimposed table item, and the superimposition queue corresponding to the other items is added to the blank (the number of serial numbers before the superimposed queue is kept unchanged) is avoided, and the superposition with the original is guaranteed. The entry is in the same dynamic update process. The communication device corresponding to the candidate MAC in the entry corresponding to the superposition queue with the most serial number in the predetermined time period should be the original received by the communication device during the period of time. And a communication device that routes the link state message of the data frame and forwards the link state message with the most original route data frame to the communication device, That is to say, the communication device having the same MAC address and the candidate MAC address (the candidate MAC in the entry corresponding to the superposition queue with the largest sequence number added) communicates with the communication device frequently during the period of time, and the mutual communication is The communication link state is better and can be used as a preferred next hop communication device of the communication device. Therefore, the superimposed value can reflect the superposition probability of successfully transmitting communication and successfully receiving communication between the communication device and the adjacent one-hop communication device of the communication device. In order to calculate the superposition probability, the first superimposition queue of the present invention is introduced. The more the routing data information received by the link state calculation module 53 for updating the second binding table in the predetermined time period as described above, the routing data information is explained. The more frequently the communication between the communication device where the sender MAC address of the routing data frame is located and the communication device, and because each new routing data information includes a new serial number, the sequence number updated within the predetermined time period The quantity can represent the above-mentioned communication frequency. To further convert the updated quantity of the serial number into a probability, the superposition queue is introduced, and the ratio of the number of serial numbers in the superimposed queue to the length of the superimposed queue is used as the ratio. Probability, that is, the superimposed value, which can effectively reflect the superposition probability of the transmission link state and the reception link state between the communication device and each adjacent one-hop communication device of the communication device, and the following reception queue and reception The value is based on the same principle, but the calculation of each probability of the present invention is not limited thereto, and the introduction of the queue is only In a preferred embodiment, it can use other methods such as statistical probability of success of a communication frequency and a predetermined period of time the ratio of the total number of the communication request, etc., the same below.

The routing data information includes a routing data frame and a MAC address of the data transceiver subunit that receives the routing data frame, and if the link state message of the routing data frame is The original sender MAC address is not the MAC address of any data transceiver subunit of the communication device, indicating that the link state message of the route data frame is another communication device (the communication device other than the communication device, including the communication) Adjacent one-hop communication devices of the device, which can be generated as the destination communication device of the communication device and forwarded by the adjacent one-hop communication device of the communication device and successfully received by the communication device, update the third binding Set the table. Specifically, the link state calculation module 53 searches the third binding table for the original sender MAC address of the link state message in the routing data frame in the routing data information, and the data transceiver sub-unit MAC address is Transmitting the data transceiver sub-unit MAC address in the routing data information (the communication device receives the data transceiving sub-unit MAC address of the routing data frame in the routing data information) and the candidate routing MAC address is the transmission of the routing data frame in the routing data information If the entry of the MAC address is not found in the third binding table, a new record is added to the third binding table, and the destination MAC address of the newly added record is in the routing data information. The original sender MAC address of the link state message in the routing data frame, the MAC address of the newly transmitted data transceiver subunit is the data transceiver subunit MAC address in the routing data information, and the candidate route MAC address of the newly added record To update the sender MAC address of the routing data frame in the routing data information, add the record and perform the following table item update process; if it can be found in the third binding table To the above entry, the following table item update process is directly performed: the destination MAC address in the third binding table is the original sender MAC address of the link state message in the routing data frame in the routing data information, and the data is transmitted and received. The sub-unit MAC address is the maximum value of the sequence number of the receiving queue corresponding to the entry of the data transceiver sub-unit MAC address in the routing data information, and the link state in the routing data information received by the link state calculating module 53 is set. The sequence number of the message is n (n is necessarily greater than m. If n is less than or equal to m, the transceiver information storage module 52 sends an invalidation response to the pre-processing module 51, and the pre-processing module 51 will route the data after receiving the invalidation response. Information discarding), in the third binding table, the destination MAC address is the original sender MAC address of the link state message in the routing data frame in the routing data information and the data transceiver sub-unit MAC address is in the routing data information. The data transmission and reception sub-unit MAC address and the candidate routing MAC address are the entries of the sender MAC address of the routing data frame in the routing data information, which are the receiving entries, and are tied to the third The destination MAC address in the fixed table is the original sender MAC address of the link state message in the routing data frame in the routing data information, and the data transceiving subunit MAC address is the entry of the data transceiving subunit MAC address in the routing data information. The (nm) empty elements are sequentially shifted into the receiving queue of the entries other than the receiving entry, and the (nm-1) empty elements and the serial number n are sequentially shifted into the receiving queue of the receiving entry, and the calculation is performed. Updating the original sender MAC address of the link state message in the routing data frame in the third binding table, and the data transceiver sub-unit MAC address is the data transceiver sub-unit MAC in the routing data information. The received value of the entry of the address. The receiving value is a ratio of the number of the serial number in the receiving queue to the length of the receiving queue, and the latest receiving time of the current receiving entry in the third binding table is the current system time. In this way, by inserting a sequence number or an empty element into the receiving queue corresponding to the entry in the third binding table, based on the first-in-first-out characteristic of the receiving queue, the received value can dynamically represent the communication device and the communication device. The probability of reception of the status of the receive link of each adjacent one-hop communication device. In the third binding table, each entry records a correspondence between a destination MAC address, a data transceiver sub-unit MAC address, a candidate routing MAC address, a received value, and a receiving time, wherein the destination MAC address is routing data in the routing data information. The original sender MAC address of the link state message in the frame, that is, the communication device corresponding to the original sender MAC address of the link state message in the received route data frame, the destination communication device of the communication device, and the data transmission and reception The sub-unit MAC address is the data transceiving sub-unit MAC address in the routing data information, that is, the data of the routing data frame received by the communication device. The MAC address of the transceiver unit, the candidate routing MAC address is the sender MAC address of the routing data frame in the routing data information, that is, the communication device that sends the routing data frame to the communication device is sent as the communication device to the destination communication device. Candidate next hop communication device for data. Therefore, the third binding table actually records the communication status of the receiving link of the communication data transmitted by the adjacent communication device of the present communication device by the communication device. Similarly, all the communication devices in the mobile communication system of the present invention are the same, so each communication device generates a new original routing data frame each time, and the sequence number of the link state message is increased by 1 on the original basis, so that other communication is performed. The link status message of each newly generated original routing data frame of the device is sent by the neighboring one-hop communication device of the communication device to the local communication device, and the link state calculation module 53 automatically updates the third binding. In the table. At the same time, the same data transceiver sub-unit MAC address and destination MAC address in the third binding table may correspond to multiple candidate MAC addresses. In order to select an optimal candidate MAC address among the multiple candidate MAC addresses, the present invention In the above update, each time the sequence number is added to the receiving queue corresponding to the receiving entry, and the receiving queue corresponding to the other entry is added to the blank (the number of serial numbers before the receiving queue is kept unchanged) is ensured, and the same is ensured. The receiving entry is in the same dynamic update process, and the communication device corresponding to the candidate MAC in the entry corresponding to the receiving queue with the highest sequence number in the predetermined time period should be sent to the communication device during the period of time. The communication device with the most number of link state messages, that is, the communication device receives the candidate MAC address (the candidate MAC address in the entry corresponding to the receive queue with the most serial number added) corresponding to the communication device in the period of time The link state message forwarded by the communication device is relatively frequent, so the received value can reflect the link state message sent by the communication device corresponding to the candidate MAC address. The reception probability successfully received by the communication device, in order to calculate the reception probability, is introduced in the above-mentioned receiving queue, and the link state calculation module 53 received by the link state calculation module 53 for updating the third binding table in the predetermined time period as described above. The more routing data information, the more frequent the communication between the communication device where the sender MAC address of the routing data frame is located and the communication device, and because each new routing data information includes a new serial number. Therefore, the number of serial numbers updated in the predetermined time period can represent the above-mentioned communication frequency. To further convert the updated number of the serial numbers into a probability, the receiving queue is introduced, and the serial number in the receiving queue is used. The ratio of the number to the length of the receive queue is taken as the probability, that is, the received value, which can effectively reflect the successful reception probability of the state of the receiving link between the communication device and each adjacent one-hop communication device of the communication device. In order to facilitate the subsequent operations, when calculating the superposition probability and the reception probability, since the number of additions of the sequence number is objective, it is preferable to select the length of the superposition queue which is the basis of the probability normalization to be consistent with the length of the reception queue. .
链路状态计算模块53接收预处理模块51发送的路由数据信息，路由数据信息包括路由数据帧和接收此路由数据帧的数据收发子单元的MAC地址，若路由数据帧的链路状态报文的原始发送方MAC地址不为本通信装置的任一数据收发子单元的MAC地址，表明此路由数据帧的链路状态报文为其它通信装置产生并且经过本通信装置的相邻一跳通信装置转发并且被本通信装置成功接收，则按照上述过程更新第三绑定表，同时在更新第三绑定表后，所述链路状态计算模块53还需要更新所述路由数据信息的路由数据帧的链路状态报文(上述由其它通信装置产生的链路状态报文)的链路状态值并将更新后的链路状态报文发送至转发模块55。也就是说链路状态计算模块53基于接收到的路由数据信息每次更新第三绑定表时，同时要更新所述路由数据信息的路由数据帧的链路状态报文的链路状态值，具体的设更新前路由数据信息(其中的路由数据帧的链路状态报文的原始发送方MAC地址不为本通信装置的任一数据收发子单元的MAC地址)的路由数据帧的链路状态报文的链路状态值为x，链路状态计算模块53读取该链路状态值为x，并在第二绑定表中查找数据收发子单元MAC地址为路由数据信息的数据收发子单元的MAC地址并且候选 路由MAC地址为路由数据信息的路由数据帧的发送方MAC地址的表项，若不能在第二绑定表中查找到上述表项，则将路由数据信息直接丢弃，链路状态报文更新过程结束；若能在第二绑定表中查找到上述表项(表明第二绑定表和第三绑定表中同一数据收发子单元MAC地址在发送和接收数据时对应有相同的候选MAC地址)，设上述在第二绑定表中查找到的表项的叠加值为y，设在第三绑定表中的本接收表项(目的MAC地址为路由数据信息中的路由数据帧中的链路状态报文的原始发送方MAC地址并且数据收发子单元MAC地址为路由数据信息中的数据收发子单元MAC地址并且候选路由MAC地址为路由数据信息中的路由数据帧的发送方MAC地址的表项)的更新后的接收值为z，此处的y可反应本通信装置中与路由数据信息中的数据收发子单元的MAC地址相同的数据收发子单元发送的数据被路由数据信息中的路由数据帧的发送方MAC地址对应的通信装置成功接收并且被该通信装置(路由数据信息的路由数据帧的发送方MAC地址对应的通信装置)转发并且又被本通信装置成功接收的叠加概率，z表示路由数据信息的路由数据帧的发送方MAC地址对应的通信装置发送的数据被本通信装置成功接收的概率，则本通信装置中MAC地址与路由数据信息的数据收发子单元的MAC地址相同的数据收发子单元发送的数据被路由数据信息的路由数据帧的发送方MAC地址对应的通信装置成功接收的概率为y/z，如前所述的叠加概率y可表示为：y＝P1*P2，其中P1表示本通信装置中与路由数据信息中的数据收发子单元的MAC地址相同的数据收发子单元发送的数据被路由数据信息中的路由数据帧的发送方MAC地址对应的通信装置成功接收的成功发送概率，P2表示路由数据信息的路由数据帧的发送方MAC地址对应的通信装置发送的数据被本通信装置中的MAC地址与路由数据信息中的数据收发子单元MAC地址相同的数据收发子单元成功接收的成功接收概率，z即与所述P2等同，因此通过y/z即得到P1，也就是本通信装置中MAC地址与路由数据信息中的数据收发子单元的MAC地址相同的数据收发子单元向路由数据信息中的路由数据帧的发送方MAC地址对应的通信装置成功发送数据的概率。并且优选的在对值y和z的归一化处理中选用同一分母，也就是叠加队列和接收队列的长度相同，这样当(y/z)<1时，将更新后的路由数据信息的路由数据帧的链路状态报文的链路状态值设置x*(y/z)，因为本通信装置与该链路状态报文的原始发送方MAC地址对应的通信装置之间的链路状态比本通信装置的相邻通信装置发送此链路状态报文的通信装置与此链路状态报文的原始发送方MAC地址对应的通信装置之间的链路状态更差，链路状态值应当减小，将更新后的链路状态报文发送至转发模块55；当(y/z)≥1时，将路由数据信息的路由数据帧的链路状态报文的链路状态值保持原值不变，因为本通信装置与该链路状态报文的原始发送方MAC地址对应的通信装置之间的链路状态不会比本通信装置的相邻通信装置(发送此链路状态报文的通信装置)与此链路状态报文的原始发送方MAC地址对应的通信装置之间的链路状态更优，并直接将所述路由数据信息的路由数据帧的链路状态报文发送至转发模块55，也将这种情况下的链路状态报文称为更新后的链路状态报文。The link state calculation module 53 receives the routing data information sent by the preprocessing module 51. The routing data information includes a routing data frame and a MAC address of the data transceiver subunit that receives the routing data frame, and if the link state message of the routing data frame is The original sender MAC address is not the MAC address of any data transceiver subunit of the communication device, indicating that the link state message of the route data frame is generated by another communication device and forwarded by the adjacent one-hop communication device of the communication device. And being successfully received by the communication device, updating the third binding table according to the foregoing process, and after updating the third binding table, the link state calculation module 53 further needs to update the routing data frame of the routing data information. The link state value of the link state message (the above link state message generated by the other communication device) and the updated link state message are sent to the forwarding module 55. That is, the link state calculation module 53 updates the link state value of the link state packet of the routing data frame of the routing data information each time the third binding table is updated based on the received routing data information. Specifically, the link state of the routing data frame of the pre-update routing data information (in which the original sender MAC address of the link state message of the routing data frame is not the MAC address of any data transceiving subunit of the communication device) is set. The link state value of the packet is x, and the link state calculation module 53 reads the link state value as x, and searches the second binding table for the data transceiver subunit of the data transceiver subunit MAC address as the routing data information. MAC address and candidate The routing MAC address is the entry of the sender MAC address of the routing data frame of the routing data information. If the entry cannot be found in the second binding table, the routing data information is directly discarded, and the link state packet update process is performed. Ending; if the above entry is found in the second binding table (indicating that the same data transceiver sub-unit MAC address in the second binding table and the third binding table corresponds to the same candidate MAC address when transmitting and receiving data) And setting the superposition value of the table item found in the second binding table as y, and setting the receiving entry in the third binding table (the destination MAC address is in the routing data frame in the routing data information) The original sender MAC address of the link state message and the data transceiving subunit MAC address is the data transceiving subunit MAC address in the routing data information and the candidate routing MAC address is the sender MAC address of the routing data frame in the routing data information. The updated received value of the entry is z, where y can reflect the data sent by the data transceiving subunit of the communication device that is the same as the MAC address of the data transceiving subunit in the routing data information. Successfully received by the communication device corresponding to the sender MAC address of the routing data frame in the data information and forwarded by the communication device (communication device corresponding to the sender MAC address of the routing data frame of the routing data information) and succeeded by the communication device again The superimposed probability of reception, z represents the probability that the data transmitted by the communication device corresponding to the sender MAC address of the routing data frame of the routing data information is successfully received by the communication device, and the data transceiver of the MAC address and the routing data information in the communication device The probability that the data transmitted by the data transceiving subunit with the same MAC address of the unit is successfully received by the communication device corresponding to the sender MAC address of the routing data frame of the routing data information is y/z, and the superposition probability y as described above may be expressed as : y = P1 * P2, where P1 represents the sender MAC address of the routing data frame in the data-transferred data information transmitted by the data transceiving sub-unit in the communication device that is the same as the MAC address of the data transceiving sub-unit in the routing data information. The successful transmission probability of the corresponding communication device successfully received, and P2 represents the routing data frame of the routing data information The data transmitted by the communication device corresponding to the sender MAC address is successfully received by the data transceiving subunit with the same MAC address in the communication device and the data transceiving subunit in the routing data information, z is the same as the P2 Equivalent, therefore, P1 is obtained by y/z, that is, the sender of the routing data frame in the routing data frame in which the MAC address of the communication device is the same as the MAC address of the data transceiving subunit in the routing data information. The probability that the communication device corresponding to the MAC address successfully transmits data. And preferably, the same denominator is selected in the normalization process for the values y and z, that is, the lengths of the superimposition queue and the reception queue are the same, so that when (y/z) < 1, the route information of the updated routing data information is routed. The link state value of the link state message of the data frame is set x*(y/z) because the link state ratio between the communication device corresponding to the original sender MAC address of the link state message is The communication device that transmits the link state message by the neighboring communication device of the communication device has a worse link state between the communication device corresponding to the original sender MAC address of the link state message, and the link state value should be reduced. If the (y/z) ≥ 1, the link state value of the link state packet of the routing data frame of the routing data information is kept unchanged. Change, because the link state between the communication device corresponding to the original sender MAC address of the link state message is no more than the communication device of the communication device (sending the communication of the link state message) Device) original transmission with this link state message The link state between the communication devices corresponding to the MAC address is better, and the link state message of the route data frame of the route data information is directly sent to the forwarding module 55, and the link state report in this case is also reported. This is called the updated link state message.
