For this case, this embodiment solves the node selection problem, and eventually, the system is implemented to have only three nodes as nodes communicating with the server for one device.
Of course, in other embodiments, the factors such as response duration, load amount, signal strength, etc. may be considered comprehensively for selection, and the specific implementation scheme is as follows:
the first scheme is as follows: device selection mechanism
The intelligent equipment can be accessed to the Internet of things system after being powered on, the node verification message is automatically broadcasted after the intelligent equipment is accessed to the system, and all nodes capable of recognizing the equipment respond to the broadcast.
(1) The intelligent equipment selects three nodes responding to the broadcast most quickly according to the rapidity of the node to reply the broadcast to establish an implicit relationship. The intelligent device receives the broadcast reply firstly and establishes the broadcast reply as an optimal node, the node receiving the second broadcast reply is a suboptimal node, and the node receiving the third broadcast reply is a standby node; after receiving the three broadcast replies, the intelligent device can automatically ignore the subsequent node replies.
(2) The response message contains information such as the signal strength of the communication of the node, and the intelligent equipment receives the signal strength responded by the node.
The intelligent equipment receives all the response messages, immediately extracts and compares the signal intensity, sorts all the signal intensities, stores the three largest results in a descending order, ignores the fourth and smaller results, times T are timed when the equipment sends out broadcasts, neglects the response messages exceeding the times T, and abandons the processing.
And selecting three nodes with the strongest signals to establish an implicit relation, wherein the node with the strongest signals is the optimal node, the node with the second signal strength is the next optimal node, and the node with the third signal strength is a spare node.
(3) The response message contains load information of the node, the load refers to the quantity of implicit relations established between the node and other intelligent devices, and the quantity conversion adopts the following formula:
load capacity: n is the node as the optimal node 2+ the node as the next optimal node 1+ the node as the backup node 1.
The intelligent device stores the node which replies the message firstly and the load of the node according to the sequence of the received node response message, the node load of the later reply message is compared with the node load of the former, the operation is repeated, the intelligent device selects the three nodes with the lowest load to establish the implicit relation for storage, and other nodes are ignored and do not communicate. The node with the least load is the optimal node, the node with the second least load is the suboptimal node, and the node with the most load among the three nodes is the standby node. The device will count time T when broadcasting, and the response message exceeding the time T will be ignored and the process will be abandoned.
(4) The response message contains information such as the signal intensity M and the load N of the node communication, the intelligent device receives the node response message, calculates the distance between the node and the intelligent device, and the intelligent device recalculates the relationship between the node and the intelligent device and selects the three nodes to establish the implicit relationship. The calculation rule is as follows:

Respectively, the value A of the optimal node > the value A of the suboptimal node > the value A of the standby node.
The intelligent device stores the implicit relationship and preferentially selects the optimal node as a communication node, the optimal node reports the implicit relationship between the device and the three nodes to the server and stores the implicit relationship in the database, and when the server issues an instruction to the device, the server can also communicate with the designated node according to the node relationship of the device. In addition, the device does not change the node confirming the hidden relationship, periodically sends a broadcast signal, confirms the hidden relationship with the node once again every time, updates the database, deletes the previous hidden relationship and replaces the previous hidden relationship with the newly confirmed hidden relationship.
The second scheme is as follows: server selection mechanism
The intelligent equipment can be accessed to the Internet of things system by switching on the power supply. The server broadcasts the node identification information automatically at variable time, all the nodes receiving the identification information start to automatically identify the surrounding equipment accessed to the Internet of things system, and the nodes feed back the identified equipment information to the server and simultaneously feed back the relevant information of the nodes. The server verifies the equipment information such as equipment ID, equipment type and the like, automatically and temporarily creates a cache region for each equipment, and the server performs operation processing on the node information uploaded to the equipment in the temporary cache region of the equipment and automatically releases the cache region after confirming the implicit relationship between the equipment and the node.
(2) The node feeds back the equipment information to the server, the feedback information also contains information such as the signal intensity of the node communication, and the server (a certain cache region) receives the signal intensity of the node reported signal:
the information is stored in a temporary buffer area in descending order, the server counts T (T is preferably 10s) time when broadcasting is sent out, all feedback information returned after the T time is exceeded is ignored, and the processing is abandoned.
The server selects three nodes with the strongest signals, wherein the node with the strongest signals is the optimal node, the node with the second signal strength is the next optimal node, and the node with the third signal strength is the standby node.
(3) The feedback message contains load information of the node, the load is the number of the node establishing an optimal node relationship, a suboptimal node relationship and a standby node relationship with other intelligent devices, and a server (a certain cache area) receives the load information and converts the number by adopting the following formula:
and (3) conversion of quantity: n is the node as the optimal node 2+ the node as the next optimal node 1+ the node as the backup node 1.
The server converts the number of the nodes which report the messages first and the number of the nodes into N according to the sequence of the messages reported by the received nodes, stores the number of the nodes which report the messages first, compares the number of the nodes which report the messages later with the number of the nodes which report the messages later, repeatedly selects three nodes with the minimum number of the nodes which are converted into N by the server, ignores other nodes and does not communicate. The node with the least N is an optimal node, the node with the least N times is a suboptimal node, and the node with the most N among the three nodes is a standby node. The server will count time T (T is preferably 10s) when broadcasting is sent out, all feedback information returned after the time T is exceeded will be ignored, and the processing is abandoned.
(4) The reporting message comprises information of the signal intensity M, the load quantity N and the like of the node communication, the server receives the node reporting message and replies a probe message which can be returned to the server again, the server records the time length t(s) of the probe message return, the distance between the node and the server is further calculated, the server recalculates the two relations and selects three nodes to establish an implicit relation with the equipment. The calculation rule is as follows:
a ═ M × x + (y/N) × z (x is preferably 60%, y is preferably 40%, z is preferably 50)
The server stores the nodes reporting the messages and the A values corresponding to the nodes, compares the A values, selects the three maximum A values, and establishes implicit relation, optimal node relation, suboptimal node relation and standby node relation between the corresponding node sequences and the equipment. Respectively, the value A of the optimal node > the value A of the suboptimal node > the value A of the standby node.
The server establishes communication relations between the selected three nodes and the equipment, stores the relations in a database, preferentially selects the optimal node as the communication node, simultaneously issues the communication relations to the equipment through the optimal node to confirm the implicit relations, and when the equipment reports data to the server, the equipment also communicates with the designated node according to the implicit relations of the equipment nodes. In addition, the server confirms that the communication relationship between the equipment and the node is not constant, the server periodically sends broadcast signals, the communication relationship between the equipment and the node is updated by the broadcast node every time, meanwhile, the database is updated, the implicit relationship is updated by the equipment, the previous implicit relationship is deleted, and the new confirmed implicit relationship is replaced.
Integrated selection mechanism
The intelligent equipment can be accessed to the Internet of things system by switching on the power supply. The node broadcasts and discovers peripheral equipment accessed to the Internet of things system, performs relationship verification communication, and replies to the broadcast by the equipment to obtain the equipment signal strength M1Feeding back to the node, and recording the feedback time t of each device by the node1(s) and comparing the feedback signal strength M of each device1Sequentially uploading to a server, and simultaneously uploading information of the node including the signal intensity M of the node2The time length t from the broadcast of the node to the information received by the server2(s) and the load amount of the node. The server stores the information of the same equipment uploaded by different nodes in a temporary cache area, and the temporary cache area is automatically released after the server confirms the communication relation of three nodes for one equipment.
