Problems solved by technology

[0002] For some sensor networks that are far away from the base station, the nodes send the node information to the base station through multiple hops, which consumes a lot of energy of the nodes, causing the nodes to fail prematurely and causing the network to be paralyzed

Embodiment Construction

[0055] Such as Figure 1-4 As shown in one of them, the present invention discloses a wireless sensor node fault diagnosis algorithm based on multiple SINK nodes, and the working principle of the present invention is described in detail as follows:

[0056] It is assumed that all the nodes in the wireless sensor network are static, that is, the position of the nodes will not move, and it is assumed that the nodes only have soft failures. Wireless sensor network can be regarded as an undirected connected graph represented by graph G, then G={V, E}. Among them, V represents the node set of sensor network, and E is the link set between nodes. If node v i , v j can carry out network communication, it is said that there is a node v i , v j There is a link e=(v i , v j ), and v i ∈ V, v j ∈V, i≠j.

[0057] Multi-sink node location selection: In order to ensure that the nodes in the target area can be diagnosed with only one-hop communication, and to ensure that the total nu...

Abstract

The invention discloses a wireless sensor node fault diagnosis algorithm based on multiple SINK nodes. The objective of the invention is to solve the problem that mobile nodes cannot be adopted for fault diagnosis. A fault diagnosis algorithm based on fault-free nodes is provided, an arrangement algorithm of the fault-free nodes is given firstly, distributed operation of node fault diagnosis is achieved, then the fault diagnosis algorithm is provided for the nodes through the fault-free nodes, and excessive energy consumption caused by multi-hop of the nodes is effectively reduced. According to the invention, most nodes only need to carry out one-hop communication with faultless nodes to realize fault diagnosis, so that the consumption of the capability is effectively reduced. The method has high fault diagnosis accuracy and low sensor energy consumption, and meets the requirements of a wireless sensor network fault diagnosis algorithm.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a wireless sensor node fault diagnosis algorithm based on multiple SINK nodes. Background technique [0002] For some sensor networks that are far away from the base station, the nodes send the node information to the base station through multiple hops, which makes the energy consumption of the nodes huge, resulting in premature failure of the nodes and network paralysis. Contents of the invention [0003] The purpose of the present invention is to provide a wireless sensor node fault diagnosis algorithm based on multiple SINK nodes. [0004] The technical scheme adopted in the present invention is: [0005] The wireless sensor node fault diagnosis algorithm based on many SINK nodes, it comprises the following steps: [0006] Step 1, obtaining the position of each sensor node in the target area of ​​the wireless sensor network; [0007] Step 2, using the K-m...
