Below in conjunction with drawings and Examples, the invention will be further described.
Wireless sensor network firmware based on XMPP upgrades management method, and its management framework as shown in Figure 1.As shown in Table 1, in the table, system management object can support all methods wherein and data, services to the method supported for the management object in this figure, but the device node in network can only support Part Methods wherein and data, services.
Table one
For the single point of management in table one and multiple spot management transmission, will introduce respectively it below.
(1) single point of management transmission
Single point of management transmission refers to sometime, and a manager only manages a node device.Be applied in the system of WSN at XMPP, single point of management transmission is mainly realized by a kind of request-response mechanism, and therefore, the realization for single point of management transmission can utilize the mode of expansion <iq/> joint to carry out.Individual cases also can utilize the mode of expansion <message/> joint to realize, and as Trouble Report, namely device node active push report information is held to its manager.Reading and writing, execution and report services can be used operate on it for the attribute using single point of management transmission means to carry out in those management objects managed.
(2) multiple spot management transmission
Multiple spot management transmission refers to that sometime, a manager can manage multiple node device.XMPP is being applied in the system of WSN, multiple spot management transmission is mainly realized by Publish-subscribe mechanism, therefore, realization for multiple spot management transmission can utilize the mode of expansion <presence/> joint to carry out, if necessary, also the mode of expansion <message/> joint can be utilized to carry out auxiliary its realize, such as, when manager issue lastest imformation complete time, the person of being managed pushes the lastest imformation that relevant information is issued to indicate oneself to receive manager to manager
For the attribute of system management object SMO, as shown in Table 2.
Table two
Attribute listed in table two is the part attribute of SMO, if necessary, also can increase more attribute, and provide more data, services.
Firmware upgrades management object UDMO and is normally used for uploading or download the occasion of bulk information to an equipment, and simultaneously it also can be used to support that the communication firmware of a download redaction or data are to a device node.The UDMO defined due to the present invention is the object in managed device, and mainly manager uploads firmware information to it, and therefore, in firmware renewal process, UDMO main manifestations of the present invention is the latter in aforementioned function.The attribute of UDMO as shown in Table 3.
Table three
The part attribute of the just UDMO listed by table three, if necessary, also can increase more attribute voluntarily, and UDMO also can provide more data, services.In the process of carrying out firmware renewal, the order may used as described in table four realizes to complete it.
Table four
Due in the process that upgrades at firmware, have a large amount of information to be transmitted, and all flow based on XML based on the communication in the XMPP system of WSN between entity device, and XML stream has larger redundancy, therefore, XMPP technology is directly used to carry out a large amount of Data Update, not only can take larger internal memory, also can a large amount of energy of consumption systems, to this, the present invention devises two kinds of passages to complete Data Update, i.e. control channel and data channel.Be applied in the system of WSN at XMPP, system by these two transmission channels separately, and distribute its respective responsibility, namely control channel generally only transmits the relevant command information based on XMPP, as firmware more newer command, request command and response command etc., and data channel transmits larger data message at this, as the firmware information etc. that need upgrade.Wherein the information of control channel transmission is based on XML stream, and the information of data channel transmission is some binary data, similar with the datapath function in traditional WSN.The process that firmware upgrades can be described as between entity first transmits the instruction of iq, presence or message message by control channel, comprise firmware more newer command, the UDP message transmission channel of out_of_band is set up again, to transmit the renewal data message of larger binary form between two entities.The method of the more new management of the firmware in the WSN that the method is traditional compared to other, has larger advantage, because its independent responsibility of each transmission channel, improves the efficiency of system communication.
Major design of the present invention two kinds of firmwares upgrade way to manages, and namely firmware upgrades single point of management transmission and firmware and upgrades multiple spot management and transmit, and will describe in detail respectively below.
1. firmware upgrades single point of management transmission
The single point of management transmission of UDMO represents that manager is sometime, only performs the associative operation of firmware renewal to some device nodes.Different and the situation only having certain or some nodes to need when carrying out firmware renewal of the file that the single point of management transmission of UDMO is mainly used in upgrading when each device node is required.Single point of management transmission described herein represents that the more new data in the XMPP message instruction and data passage in control channel is all point-to-point communication.
The performing step of UDMO single point of management transmission is as follows:
A) be first that device node is set up UDP with server respectively with manager and is connected, its transmission channel is control channel;
B) when manager needs to carry out firmware renewal to device node, iq message read request is namely sent to device node, with the association attributes of UDMO in fetch equipment node, as OperationsSupported and State etc.;
C), after device node receives this request, namely reply an iq message to manager and read response;
D), after manager receives this response, the value returned according to UDMO judges currently whether can carry out firmware renewal to equipment.If not, then firmware renewal is not carried out to equipment; If so, then start StartUpload order to reach upload operation agreement with device node, and send corresponding message message to device node to represent that manager will carry out firmware renewal to device node;
E) after device node receives this message, namely start DownloadData order to reply gerentocratic request, and send corresponding message message and inform whether it agrees to carry out firmware renewal to manager.
F) order more than in these steps is all transmitted in control channel.
G) namely to transmit firmware more before new data manager, need the UDP message passage setting up out_of_band between device node, to realize the direct communication of manager and device node.
H) manager by this data channel with binary form transmit a large amount of firmwares more new data in its just asked device node.
K) in the process, device node may arrange the time of download firmware lastest imformation, the DownloadPrepTime namely in table three, if the time does not expire, when the data transfer is complete, device node can to manager push message message with indicate transmission complete; If time is up the phase, namely device node can start EndDownload order to stop the transmission of firmware lastest imformation.Message message herein transmits in previous set up control channel.
Due to described herein be the single point of management transmission of UDMO, therefore, it realizes using mode of expansion <iq/> joint to carry out.The implementation procedure of UDMO single point of management transmission as shown in Figure 2, in this figure, when manager needs to carry out firmware renewal to device node, then send iq message read request to device node with the OperationsSupported attribute of UDMO in fetch equipment node and State attribute, if these object properties of device node show it support that download and current state are for idle, then manager can carry out firmware renewal to it, and in its implementation procedure, each message format design is as follows.
Iq message read request form:
Iq message reads response format (success):
The value of X and Y herein can see table three.
Iq message reads response format (mistake):
Wherein, the value of error-type can see the description of the RFC6120 in IETF.
The message message format that first time sends:
Property value 0 wherein represents that the current state of manager is idle condition, carry out upload operation.
The message message format that second time sends:
The description of X herein and value thereof are in shown in table three.
The message message format that third time sends:
2. firmware upgrades multiple spot management transmission
The multiple spot management transmission of UDMO represents that manager can provide firmware to upgrade management service to multiple equipment simultaneously, namely a manager can once to the associative operation that multiple equipment execution firmware upgrades, as issued oneself state information to multiple equipment, and firmware more new data etc. is issued to multiple equipment simultaneously.The multiple spot management transmission of UDMO comprises following several situation.
(1) support that the firmware of firmware information clean culture upgrades
This kind of situation represents that manager only broadcasts XMPP message instruction, and to the firmware in data channel more new data carry out clean culture, belong to multiple spot management transmission.
When the firmware of manager's equipment in supervising the network upgrades, because each equipment in network needs the file of renewal different, now, manager can by only broadcast XMPP message instruction, and the method for clean culture firmware more new data, with the energy of the system of saving, but no matter when, equipment sends to gerentocratic information to be all the point-to-point communication mode adopted.Manager herein broadcasts XMPP message instruction and refers to that manager sends XMPP message instruction not with to attribute to server, XMPP message received by it is sent to destination node by server more in a broadcast manner, if the equipment receiving these message is destination node, then perform follow-up corresponding operating; If the equipment receiving these message is routing device, the message that router then uses the method flooded it to be received forwards, and the data flow that namely router is received sends from other interfaces all except that interface just receiving data.Use the advantage flooded to be comparatively huge with under complicated situation at network, what source data also can be very fast is diffused into each object equipment.But adopting floods also also exists a larger problem, namely floods and can produce a large amount of repetitive data packet, suppress flooding process unless certain measures are taken, otherwise unlimited many packets will be produced, also can consume larger bandwidth simultaneously.Suppress packet to spread unchecked technology be the packet allowing router trace flood, thus avoid second time send them.A kind of mode realizing this target allows each source router fill out a sequence number when receiving the packet of from host, and then each router is that each source router prepares a table, to record the sequence number from source router observed; If inbound data bag in this table, then abandons this packet, no longer forwards this packet to other router.In order to avoid this table ad infinitum expands, each table should use a counter k as parameter, represents until all sequence numbers of k have been observed all, if router receives sequence number k packet in the past again, directly abandons, no longer forward, until finally all information arrives destination node all.
Support that the performing step that the firmware of firmware information clean culture upgrades is as follows:
A) be first that device node is set up UDP with server respectively with manager and is connected, its transmission channel is control channel;
B) manager broadcasts firmware renewal instruction, shows to carry out firmware renewal to equipment.
C) after device node receives this message, namely start DownloadData order to reply gerentocratic request, and send corresponding message message and inform whether it agrees to carry out firmware renewal to manager.
D) after manager receives this message, when namely will send firmware lastest imformation, then the UDP message passage of out_of_band is set up with each equipment, and with the larger firmware more new data of the format transmission of binary data information.
E) after equipment receives the firmware lastest imformation of manager's transmission, namely send message Indication message and inform that manager's firmware lastest imformation is transmitted.
In whole communication process, have employed 2 kinds of transmission channels altogether.In above-mentioned 5 steps, step a) all completes to the information transmitted in c) in control channel, and the information that step d) is transmitted completes in data channel, and the message message in step e) is transmitted in control channel.
Due to described herein be the multiple spot management transmission of UDMO, therefore, its realization can utilize the mode of expansion <presence/> joint to carry out.For the information that equipment pushes to manager, then can realize with expansion <message/> joint, as shown in Figure 3, the format design for XMPP message used in whole process of changing plan is as follows for its specific implementation process.
Presence message format:
As described in table two, when the Status property value of SMO is 0, represents that the current state of SMO is idle, can firmware renewal be carried out.Herein manager release news 0 be namely firmware upgrade instruction.Use the message format not with to attribute in structure <presence/> joint to realize the broadcast that firmware upgrades instruction herein.
Equipment first time sends the form of message message and aforementioned UDMO single point of management and transmits the second time designed to send message message format the same herein,
For the message Indication message that the second time of equipment herein sends, its form and aforementioned UDMO single point of management are transmitted the third time designed to send message message format the same.
(2) support that the firmware of firmware information multicast upgrades
In this kind of situation, manager broadcasts the XMPP message instruction in control channel, and carries out multicast to the more new data in data channel, belongs to multiple spot management transmission.
Be applied in the system of WSN at XMPP, when the file upgraded needed for the hop neighbor equipment being positioned at manager's periphery is all the same, the firmware more new management that the mode of multicast firmware more new data realizes these equipment can be adopted.Herein, manager obtains the information of one hop neighbor node is realized by the association attributes in access topology information management object.Manager is sent message instruction by the mode of broadcast and is sent firmware more new data in the mode of multicast, the energy ezpenditure that some are unnecessary can be saved, but no matter when device node sends to gerentocratic information to be all adopt point-to-point communication mode, and implementation step is as follows.
A) be first that device node is set up UDP with server respectively with manager and is connected, its transmission channel is control channel;
B) manager broadcasts firmware renewal instruction, shows to carry out firmware renewal to equipment.
C) after device node receives this message, namely start DownloadData order to reply gerentocratic request, and to manager, transmission message message informs whether it agrees to carry out firmware renewal.
D) manager obtains one hop neighbor table by access topology information management object.After the hop neighbor device node that manager is all with it is all reached an agreement and be ready, then set up the UDP message passage of out_of_band with these device nodes, and then multicast firmware more new data in the equipment of multicast address.Multicast address is herein the address of all hop neighbor device node of manager.
E) after device node receives the firmware lastest imformation of manager's transmission, namely send message Indication message and inform that manager's firmware lastest imformation is transmitted.
Due to described herein be the multiple spot management transmission of UDMO, therefore, its realization can utilize the mode of expansion <presence/> joint to carry out.For the information that equipment pushes to manager, then can realize with expansion <message/> joint, its specific implementation process as shown in Figure 4, the presence message transmitted in this figure, its form is the same with the presence message format in the firmware Renewal Design of above-mentioned support firmware information clean culture.
Equipment first time sends the form of message message and aforementioned UDMO single point of management and transmits the second time designed to send message message format the same herein,
For the message Indication message that the second time of equipment herein sends, its form and aforementioned UDMO single point of management are transmitted the third time designed to send message message format the same.
(3) broadcast of the whole network upgrades
The broadcast of the whole network upgrade refer to manager to XMPP message instruction and firmware more new data all broadcast, it is all the same occasion that this kind of mode is applicable to the required file upgraded of all equipment, belongs to multiple spot management transmission.
The firmware update mode that this section adopts is: manager broadcast XMPP message instruction and firmware more new data in node device or routing device, if the equipment receiving these message is destination node, then its implementation with support the firmware of firmware information multicast upgrade described in implementation the same, namely these nodes are similar to a gerentocratic hop neighbor node, difference is, in supporting the firmware of firmware information multicast to upgrade, gerentocratic destination address is multicast address, and gerentocratic destination address is broadcast address herein; If the equipment receiving these message is routing device, the message that router then uses the aforesaid method that floods it to be received forwards.
Broadcast for the whole network upgrades, and design implementation step is as follows.
A) be first that device node is set up UDP with server respectively with manager and is connected, its transmission channel is control channel;
B) manager broadcasts firmware renewal instruction, shows to carry out firmware renewal to equipment.
C) after object device node receives this renewal instruction, namely start DownloadData order to reply gerentocratic request, and send corresponding message message and inform whether it agrees to carry out firmware renewal to manager.
D) after all object device nodes are all reached an agreement with manager and be ready, manager coordinates firmware update time, and sets up the UDP message transmission channel of out_of_band with all devices;
E) after establishing data channel, manager broadcast firmware more new data to the router in network or object device node, when router receives this firmware more after new data, namely adopt the mode flooded that these firmwares are upgraded data retransmission to other router and object device node;
F) when object device node receives firmware more after new data, namely send message Indication message by control channel and inform that manager's firmware lastest imformation is transmitted.
Due to described herein be the multiple spot management transmission of UDMO, therefore, its realization can utilize the mode of expansion <presence/> joint to carry out.For the information that equipment pushes to manager, then can realize with expansion <message/> joint, its specific implementation process as shown in Figure 5.The presence message transmitted in this figure, presence message format designed during its form upgrades with the firmware of above-mentioned support firmware information clean culture is the same.
Equipment first time sends the form of message message and aforementioned UDMO single point of management and transmits the second time designed to send message message format the same herein,
For the message Indication message that the second time of equipment herein sends, its form and aforementioned UDMO single point of management are transmitted the third time designed to send message message format the same.
