Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It should be apparent that the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
Example one
First, it should be understood that in the current wireless ad hoc network scheme, communication links between different communication devices usually transmit communication data by wire, or wirelessly transmit communication data by Wi-Fi 2.4G or Wi-Fi 5G/6G, and communication data cannot be transmitted by two communication links at the same time, and in this context, other application patents filed on the same day have elaborated networking methods of multi-link communication, specifically using technologies such as VLAN aggregation, super-VLAN and Sub-VLAN, so as to avoid technical defects such as communication loop generation or communication disturbance when link communication is implemented, so as to improve flexibility between different communication devices of the wireless ad hoc network, for example, referring to fig. 1, which is a schematic diagram showing link communication, where a lower slave device is connected to 2.4G and 5G of its upper device at the same time, if the lower slave device still maintains wired connection and bandwidth meets requirements, the WiFi connection can be broken, and the lower slave device can also maintain continuous connection, and in the current, if the lower slave device normally maintains wired connection with the upper device and the bandwidth meets requirements, and thus, the communication between the lower slave device always maintains consistency with the communication links, and the communication data transmission between the upper device is not changed due to the situation that the communication links of the lower slave device, the communication links, and the communication between the lower slave device, and the communication devices are not maintained, and the communication devices, the situation of unstable data throughput is easy to occur due to the problem of link bandwidth, and further the internet access experience of the user is poor, so a method for improving the data transmission stability in the asymmetric link communication process is urgently needed at present.
In a first embodiment of the asymmetric link data transmission method of the present application, referring to fig. 2, the asymmetric link data transmission method includes:
step S10, obtaining data to be transmitted through an initial communication link of the target communication equipment, wherein the initial communication link comprises an uplink communication link and a downlink communication link;
step S20, if the uplink communication link and the downlink communication link are detected to be inconsistent, converting the data to be transmitted to obtain target transmission data;
and step S30, transmitting the target transmission data through a target communication link corresponding to the target transmission data.
In this embodiment, it should be noted that the communication link is used to represent a physical channel between communication devices of the wireless ad hoc network, and specifically may be a unidirectional communication link or a bidirectional communication link, and after the wireless ad hoc network is successfully configured, the communication link exists between the communication devices of the wireless ad hoc network to implement transmission of communication data, where the wireless ad hoc network manages the communication devices of the entire wireless ad hoc network through the master communication device, and specifically may be one communication device, and other communication devices of the wireless ad hoc network except the master communication device are provided
The devices are all slave communication devices, that is, the slave communication device is used for characterizing the communication device 5 managed by the master communication device, and specifically may be one or more, in a specific embodiment, the master communication device may manage a plurality of slave communication devices, and the slave communication device may be a communication device directly connected to the master communication device, or a communication device indirectly connected to the master communication device by connecting the slave communication device to the master communication device, thereby forming a multi-level networking, so that the asymmetric link data transmission method may be applied to a target communication device of a wireless ad hoc network,
that is, the target communication device is used to characterize an intermediate communication device of the wireless ad hoc network, and specifically may be a communication device in which 0 exists an upper level device and a lower level device.
Additionally, it should be noted that, after the wireless ad hoc network is successfully configured, the target communication device may serve as a data sending end to send communication data to other communication devices of the wireless ad hoc network, may also serve as a data receiving end to receive communication data sent by other communication devices of the wireless ad hoc network, and may also serve as a middle communication device
And an inter-transmission node to realize transmission of communication data, wherein the initial communication link is used for representing a communication link between the target communication device and other directly-connected communication devices after the 5 wireless ad hoc network is initially established and stabilized, and the communication link comprises an uplink communication link and a downlink communication link, wherein the uplink communication link is used for representing a communication link between the target communication device and a directly-connected superior device of the target communication device, and the downlink communication link is used for representing a straight line between the target communication device and the target communication device
For example, referring to fig. 3, fig. 3 is a schematic diagram of a network 0 representing a wireless ad hoc network, where the wireless ad hoc network is a two-hop ad hoc network, and assuming that the communication device 1 transmits communication data to the communication device 6, and the communication device 3 is a target communication device, a communication link between the communication device 1 and the communication device 3 is an uplink communication link, and a communication link between the communication device 3 and the communication device 6 is a downlink communication link.
Additionally, it should be noted that the uplink communication link may specifically include a wired communication link and wireless communication links of 5 and different communication frequency bands, and the communication frequency bands may specifically be 2.4GHz, 5GHz, and 6GHz, and during the networking process of the wireless ad hoc network, one or more communication links may be established between communication devices of the wireless ad hoc network, and a configuration synchronization process and a protocol specification based on a wireless ad hoc network protocol ensure communication data synchronization, and after the networking is completed, a master communication device of the wireless ad hoc network may perform slave communication to a slave communication device
The device synchronizes configuration information, where the configuration information may be a username and a password of a wireless ad hoc network, 0 selection of a communication channel, a maintaining parameter of network stability, and backhaul link information of different communication bands, where the backhaul link information specifically includes an ssid (Service Set Identifier), a password and an encryption manner of a backhaul link, and the like.
Additionally, it should be noted that the data to be transmitted is used to represent communication data waiting for transmission via the target communication device, and after the wireless ad hoc networking succeeds, the target communication device may serve as a communication medium for data transmission between a superior device of the target communication device and a subordinate device of the target communication device, so as to implement data interaction between the superior device of the target communication device and the subordinate device of the target communication device, for example, after the superior device of the target communication device transmits communication data to be transmitted to the target communication device in a primary backhaul manner or a multi-backhaul manner, the target communication device transmits the communication data to the subordinate device of the target communication device through the target communication link. However, in the stabilized wireless ad hoc network, the communication link between the target communication device and the upper device of the target communication device and the communication link between the target communication device and the lower device of the target communication device do not necessarily maintain a symmetrical configuration. For example, referring to fig. 4, fig. 4 is a link diagram illustrating an asymmetric multilink of a wireless ad hoc Network, where a communication device D is an upper device of a target communication device, a communication device E is a target communication device, a communication device F is a lower device of the target communication device, communication links exist between the communication device E and the communication device D, but the communication links between the communication device E and the communication device D do not match the communication links between the communication device E and the communication device F, that is, a wireless communication link a, a wireless communication link b, and a wired communication link c exist between the communication device E and the communication device D, where the communication frequency bands of the wireless communication link a and the wireless communication link D may be the same, such as 2.4GHz, the communication frequency bands of the wireless communication link b and the wireless communication link c may be the same, such as 5GHz, the wireless communication link a is configured as sub-Virtual Local Area 1.1.1.1 (Virtual Local Area 1.1.1-Local Area 2.1.2, 2-Local Area 1.2.2.1.2-Local Area sub.1.2.2.1-Local Area sub.1.2.2-Local Area communication link c is configured as Virtual Area communication link 1.2-Local Area communication link.
As an example, steps S10 to S30 include: periodically acquiring, over an uplink communication link between the target communication device and the target device, communication data waiting for transmission via the target communication device; if the link identification of the uplink communication link is detected to be inconsistent with the link identification of the downlink communication link of the target communication equipment, converting the data to be transmitted to obtain target transmission data, wherein the target transmission data is used for representing the data to be transmitted through the target communication link, the target communication link is a communication link with the highest stability between the target communication equipment and the downlink equipment of the target communication equipment, and the conversion of the data to be transmitted can be carried out according to the principles of load balance, reliability, priority and the like; and transmitting the target transmission data to the drop-on device of the target communication device through a target communication link corresponding to the target transmission data.
Wherein, if the uplink communication link and the downlink communication link are detected to be inconsistent, the step of converting the data to be transmitted to obtain the target transmission data comprises:
step A10, if it is detected that a first link bandwidth of the uplink communication link is greater than a second link bandwidth of the downlink communication link, converting the data to be transmitted to obtain the target transmission data; or the like, or, alternatively,
step A20, if it is detected that the first link bandwidth is smaller than the second link bandwidth, converting the data to be transmitted to obtain the target transmission data.
In this embodiment, it should be noted that, since the topology structure of the wireless ad hoc network is relatively complex and is in real-time dynamic change, in order to more accurately represent asymmetry of communication links between the target communication device and an upper device of the target communication device and a lower link of the target communication device during data transmission, the target communication device may detect link bandwidths of an uplink communication link and a downlink communication link, so as to objectively reflect whether a link bandwidth between the target communication device and the upper device of the target communication device is consistent with a link bandwidth between the target communication device and a lower device of the target communication device.
As an example, steps a10 to a20 include: respectively acquiring a first link bandwidth of the uplink communication link and a second link bandwidth of the downlink communication link, and if the first link bandwidth is detected to be larger than the second link bandwidth, converting the data to be transmitted to obtain the target transmission data; or the like, or a combination thereof,
and respectively acquiring a first link bandwidth of the uplink communication link and a second link bandwidth of the downlink communication link, and if the first link bandwidth is detected to be smaller than the second link bandwidth, converting the data to be transmitted to obtain the target transmission data.
The step of converting the data to be transmitted to obtain target transmission data comprises the following steps:
step B10, acquiring a transmission link identifier of the data to be transmitted;
and step B20, converting the data to be transmitted according to the transmission link identification to obtain the target transmission data.
In this embodiment, it should be noted that the transmission link identifier is used to identify a data transmission link of the data to be transmitted between the target communication device and the data receiving device of the data to be transmitted, and specifically may be a local area network name or a local area network address. By converting the transmission link identification, the data to be transmitted can be distributed to a more stable communication link for transmission, so that the data loss condition in the data transmission process is avoided.
As an example, steps B10 to B20 include: extracting a transmission link identifier from the data to be transmitted; and acquiring at least one communication link between the target communication equipment and the lower hanging equipment of the target communication equipment, determining a target communication link according to the corresponding relation of link bandwidths between each communication link and the transmission link corresponding to the transmission link identifier, converting the transmission link identifier of the data to be transmitted into the link identifier of the target communication link, and acquiring the target transmission data.
The step of determining the target communication link according to the correspondence between the communication links and the link bandwidths between the transmission links corresponding to the identification of the transmission link identification may specifically be: respectively obtaining a third link bandwidth of each communication link and a fourth link bandwidth of the transmission link, respectively calculating a bandwidth difference between each third link bandwidth and the fourth link bandwidth, and taking the link bandwidth corresponding to the third link bandwidth with the smallest bandwidth difference as the target communication link, wherein the bandwidth difference may be specifically zero.
Wherein, the step of converting the data to be transmitted according to the transmission link identifier to obtain the target transmission data comprises:
step C10, detecting whether the first communication frequency band of the initial communication link is consistent with the second communication frequency band of the secondary communication link corresponding to the transmission link identification;
step C20, if yes, converting the transmission link identification into a first link identification of a wired communication link to obtain the target transmission data;
and step C30, if not, converting the transmission link identifier into a second link identifier of the wireless communication link with the same frequency band as the first communication frequency band, and obtaining the target transmission data.
In this embodiment, it should be noted that, in the process of establishing the wireless multi-link ad hoc network, different communication links are usually established with communication links in the same communication frequency band, so as to improve the transmission efficiency. Therefore, in order to accelerate the conversion efficiency of the data to be transmitted, the communication frequency bands of the initial communication link and the secondary communication link can be directly compared in some communication links including the wired communication link and the first communication frequency band of the initial communication link, so that the data to be transmitted is converted, and the purpose of stably transmitting the data to be transmitted is achieved. And the secondary communication link is used for representing a communication link for transmitting the data to be transmitted between the target communication equipment and the data receiving communication equipment of the data to be transmitted. Referring to fig. 5, fig. 5 is a schematic diagram illustrating asymmetric multilink data transmission, where the communication device 11 is a higher-level device of the communication device 12, the communication device 12 is a target communication device, and the communication device 13 is a lower-level device of the communication device 12, and it is assumed that data to be transmitted is transmitted from the communication device 11 to the communication device 13 via the communication device 12, where the communication device 11 transmits the data to be transmitted to the communication device 12 through a 2.4GHz band communication link, and then the communication link x, the communication link y, or the communication link z between the communication device 12 and the communication device 13 may be secondary communication links.
As an example, steps C10 to C30 include: detecting whether a first communication frequency band of the initial communication link is consistent with a second communication frequency band of a secondary communication link corresponding to the transmission link identifier, wherein the secondary communication link is routed through the transmission link identifier; if the first communication frequency band is detected to be consistent with the second communication frequency band, converting the transmission link identifier into a first link identifier of a wired communication link to obtain the target transmission data; if the first communication frequency band is detected to be inconsistent with the second communication frequency band, selecting a wireless communication link identical to the first communication frequency band from communication links between the target communication device and the drop-on device of the target communication device, and converting the transmission link identification into a second link identification of the wireless communication link to obtain the target transmission data.
The step of obtaining the transmission link identifier of the data to be transmitted includes:
step D10, according to the networking information of the wireless ad hoc network, determining secondary communication equipment which transmits the data to be transmitted together with the target communication equipment;
step D20, using a link identifier of a secondary communication link between the secondary communication device and the target communication device as the transmission link identifier.
In this embodiment, it should be noted that the secondary communication device is used to characterize the communication device that receives the data to be transmitted, and may specifically be one or more communication devices. Due to the fact that the topological structure of the wireless ad hoc network is complex, when the wireless ad hoc network is changed from a symmetrical topological structure to an asymmetrical topological structure, the transmission link identification under the current asymmetrical topological structure can be obtained in real time according to networking information periodically broadcasted in the wireless ad hoc network, wherein the networking information is used for representing networking conditions among communication devices of the wireless ad hoc network, and specifically can be a periodically broadcasted networking message. The secondary communication equipment corresponding to the target communication equipment can be obtained through inquiry of the networking information, a communication link (secondary communication link) between the secondary communication equipment and the target communication equipment can be further obtained, and finally a link identifier of the secondary communication link is used as a transmission link identifier.
As an example, steps D10 to D20 include: inquiring secondary communication equipment which transmits the data to be transmitted together with the target communication equipment by taking networking information of the wireless ad hoc network as an index; and taking the wireless link identification of the secondary communication link between the secondary communication device and the target communication device as the transmission link identification.
As an example, steps D10 to D20 include: inquiring secondary communication equipment which transmits the data to be transmitted together with the target communication equipment by taking the networking information of the wireless ad hoc network as an index; and taking the wired link identification of the secondary communication link between the secondary communication device and the target communication device as the transmission link identification.
The target communication link comprises a target wired communication link and a target wireless communication link, and the step of transmitting the target transmission data through the target communication link corresponding to the target transmission data comprises the following steps:
step E10, transmitting the target transmission data through the target wired communication link; or the like, or, alternatively,
step E20, transmitting the target transmission data through the target wireless communication link.
In this embodiment, it should be noted that, when the target communication device transmits target transmission data to the secondary communication device, a target wireless communication link or a target wired communication link may be used for targeted transmission according to an actual data transmission requirement, where the target wireless link may be a 2.4GHz band communication link or a 5GHz band communication link.
As an example, steps E10 to E20 include: transmitting the data to be transmitted to the secondary communication equipment through a 2.4GHz frequency band communication link; or the like, or, alternatively,
and transmitting the data to be transmitted to the secondary communication equipment through the target wired link.
The embodiment of the application provides an asymmetric link data transmission method, which is applied to target communication equipment of a wireless ad hoc network, namely, data to be transmitted is obtained through an initial communication link of the target communication equipment, wherein the initial communication link comprises an uplink communication link and a downlink communication link; if the uplink communication link and the downlink communication link are detected to be inconsistent, converting the data to be transmitted to obtain target transmission data; and transmitting the target transmission data through a target communication link corresponding to the target transmission data. When the uplink communication link and the downlink communication link of the target communication device are inconsistent, the converted data to be transmitted (target transmission data) is transmitted through the target communication link, so that the purpose of converting the communication link for the data to be transmitted can be achieved. Namely, the purpose of flexibly controlling the transmission link of the data to be transmitted after the data to be transmitted is acquired through the initial communication link is achieved. When the communication data is not transmitted, the communication device always depends on a communication link between the superior device of the communication device and the communication device, and then the communication link with the same frequency band as the communication link is matched for the communication data, so that the communication data is transmitted to the downlink device of the communication device. Therefore, the technical defect that when the communication links of the communication equipment and the communication equipment are not always consistent, namely when the wireless ad hoc network has an asymmetric link, if the communication equipment still receives communication data, the communication link relied on transmits the communication data, the data throughput is unstable, and the internet surfing experience of a user is poor is overcome. Therefore, the data transmission stability in the asymmetric link communication process is improved.

On this basis, the step of determining, according to the networking information of the wireless ad hoc network, a secondary communication device that transmits the data to be transmitted together with the target communication device includes:
step F10, inquiring candidate communication equipment which transmits the data to be transmitted together with the target communication equipment according to networking information of the wireless ad hoc network, wherein the candidate communication equipment comprises first candidate communication equipment and second candidate communication equipment;
step F20, if the candidate communication device is the first candidate communication device, taking the first candidate communication device as the secondary communication device;
step F30, if the candidate communication device is the second candidate communication device, determining the secondary communication device according to the corresponding relation between the data to be transmitted and the second candidate communication device.
In this embodiment, it should be noted that the candidate communication device is configured to characterize a communication device that has an initial communication link with the target communication device and waits for receiving data to be transmitted, that is, a communication device that is directly connected to the target communication device in a current stable wireless ad hoc network and can perform data transmission through the communication link to receive the data to be transmitted. Due to the fact that the topological structure of the wireless ad hoc network is complex generally, when the number of the secondary communication devices is multiple, the data to be transmitted can be transmitted to the actually needed secondary communication devices in a targeted mode on the premise that the transmission stability of the data to be transmitted is guaranteed. For example, if the target communication device includes a secondary communication device X and a secondary communication device Y, 2.4GHz band communication links exist between the target communication device and the secondary communication device X, and the secondary communication device Y, and the target communication link corresponding to the target transmission data is a 2.4HGz band communication link, if the target transmission data is transmitted to the secondary communication device Y through the communication link between the target communication device and the secondary communication device Y, the secondary communication device X actually needing to receive the data to be transmitted may not receive the data to be transmitted. When a plurality of candidate communication devices of the target communication device under the wireless ad hoc network are provided, determining a second communication device in the plurality of candidate communication devices according to a data identifier carried by the data to be transmitted, wherein the data identifier may specifically be a data receiving local area network address or a data receiving local area network name, and the like. Referring to fig. 7, fig. 7 is a schematic diagram showing different types of candidate communication devices, in which the communication device 23, the communication device 33, and the communication device 34 are all candidate communication devices.
As an example, steps F10 to F30 include: inquiring candidate communication equipment for the target communication equipment to jointly transmit the data to be transmitted by using the networking information of the wireless ad hoc network as an index, wherein the candidate communication equipment comprises first candidate communication equipment and second candidate communication equipment, the first candidate communication equipment is used for representing one candidate communication equipment, and the second candidate communication equipment is used for representing a plurality of candidate communication equipment; if the candidate communication device is a candidate communication device, taking the candidate communication device as the secondary communication device; and if the candidate communication equipment is a plurality of candidate communication equipment, taking the candidate communication equipment consistent with the data identification carried by the data to be transmitted as the secondary communication equipment.
The embodiment of the application provides a secondary communication device determination method. That is, according to networking information of the wireless ad hoc network, candidate communication devices which transmit the data to be transmitted together with the target communication device are inquired, wherein the candidate communication devices comprise a first candidate communication device and a second candidate communication device; if the candidate communication device is the first candidate communication device, taking the first candidate communication device as the secondary communication device; and if the candidate communication equipment is the second candidate communication equipment, determining the secondary communication equipment according to the corresponding relation between the data to be transmitted and the second candidate communication equipment. Compared with a mode that the lower hanging device of the target communication device is directly used as the secondary communication device, the data to be transmitted is transmitted to the secondary communication device. According to the embodiment of the application, the secondary communication equipment for receiving the data to be transmitted is screened out in the candidate communication equipment in a targeted manner, and then the data to be transmitted is transmitted to the secondary communication data through the target communication link between the secondary communication equipment and the target communication equipment, so that the purpose of accurately transmitting the data to be transmitted to the secondary communication equipment can be achieved, and therefore the situation that the communication data are lost when the data to be transmitted is transmitted to the lower hanging equipment of the communication equipment through the target communication link between the communication equipment and the lower hanging equipment of the communication equipment is avoided, and therefore a foundation is laid for improving the accuracy of data transmission in the asymmetric link communication process.
