Embodiment 1

[0031] From figure 2 It can be seen that node A-node F, node A and node D are selected as positioning nodes, node search is performed with a radius R=3m, node B and node C are in the first wireless sensor subnetwork with node A as the sink node; Node E and node F are in the second wireless sensor subnet with node D as the sink node, from figure 2 It can be seen that there is no node in node A-node F that is in the first wireless sensor subnet and the second wireless sensor subnet at the same time, and at the same time, there is no node that neither belongs to the first wireless sensor subnet nor belongs to the second wireless sensor subnet Two nodes of the wireless sensor subnetwork, figure 2 That is, the updated node assignment graph.

Embodiment 2

[0033] From image 3 It can be seen that node A-node F, node A and node D are selected as the positioning nodes, and the node search is carried out with the radius R=3m. In the network; node E and node F are in the second wireless sensor subnetwork with node D as the sink node, from image 3 It can be seen that node E is included in both the first wireless sensor subnet and the second wireless sensor subnet. Since the distance from node E to node D is smaller than the distance from node E to node A, node E is assigned to the second wireless sensor subnet The second wireless sensor subnet, updating nodes; at this time, among node A-node E, there is no node in the first wireless sensor subnet and the second wireless sensor subnet at the same time, and at the same time, there is no node that does not belong to the first wireless sensor subnet A wireless sensor subnet also does not belong to the nodes of the second wireless sensor subnet.

Embodiment 3

[0035] From Figure 4 It can be seen that node A-node F, node A and node D are selected as the positioning nodes, and the node search is carried out with the radius R=3m. network; node E is in the second wireless sensor subnetwork with node D as the sink node, from image 3It can be seen that node E is included in both the first wireless sensor subnet and the second wireless sensor subnet. Since the distance from node E to node D is smaller than the distance from node E to node A, node E is assigned to the second wireless sensor subnet Two wireless sensor subnets, update nodes; node F is neither a node belonging to the first wireless sensor subnet nor a node belonging to the second wireless sensor subnet, because the distance from node F to node D is less than the distance from node F to node A distance, so node F is allocated to the second wireless sensor subnet, at this time, at this time, among node A-node E, no node is in the first wireless sensor subnet and the second ...

Abstract

The invention discloses a positioning node based node distributing method in the wireless sensing network. By the positioning node based node distributing method, nodes in the wireless sensing network can be effectively classified into several wireless sensing subnets by taking a positioning node as a gathering node, and the problem that each node is provided with a positioning module in order to acquire the position information of the nodes in the conventional wireless sensing network while the nodes within a certain range can be marked by the same position information is solved. The positioning nodes corresponding to the other nodes in the wireless sensing network can be marked by the position information of the positioning nodes, and the number of the positioning modules near the nodes can be effectively decreased.

Description

technical field [0001] The invention belongs to the field of wireless sensor networks, and more specifically relates to a node allocation method in a wireless sensor network based on positioning nodes. Background technique [0002] Wireless sensor network is an emerging research field, which has great potential application prospects in military, environment, health, family, business and many other fields. The wireless sensor network node is the basic unit of the network, the rapid development of the wireless sensor network has brought many challenges to the design and management of the wireless sensor network node. [0003] Wireless sensor network is a distributed self-organizing network integrating data collection, processing and communication functions.
