Abstract

The invention relates to a wireless sensor network clustering routing method and system based on maximum between-class variance. The method comprises the following steps: calculating a node angle according to a base station coordinate and a node coordinate; based on a wireless sensor network node energy consumption model, determining the optimal position and the optimal number of cluster heads; determining an inter-cluster node angle variance according to a node angle based on the optimal number of cluster heads; determining the number of nodes in each cluster according to the inter-cluster node angle variance; determining an inter-cluster node number variance according to the optimal number of cluster heads and the number of nodes in each cluster; determining a clustering multi-objective optimization function according to the inter-cluster node angle variance and the inter-cluster node number variance, and solving an optimal solution; segmenting all the arranged nodes into a plurality of optimal clusters according to the optimal angle segmentation threshold; and determining an optimal cluster head position circle which takes the base station as a circle center and takes the optimal cluster head position as a radius, and node residual energy, and selecting an optimal cluster head in each optimal cluster. According to the invention, the network energy consumption is effectively reduced and equalized.

Description

technical field

[0001] The invention relates to the field of information communication, in particular to a wireless sensor network clustering routing method and system based on maximum inter-class variance. Background technique

[0002] Wireless Sensor Networks (WSNs) is a mobile ad-hoc network composed of a large number of tiny, cheap and low-power sensor nodes. These nodes cooperate with each other to complete application tasks and perceive The data is forwarded to the central collection and aggregation node.

[0003] In the WSN clustering routing protocol, such as figure 1 As shown in , all nodes are divided into clusters according to a certain method, and each cluster is also called a cluster. A node in the cluster is elected as the cluster head, responsible for collecting and fusing data from other nodes in the cluster, and then forwarding the fused data to the base station for processing. Because the cluster head undertakes the fusion and forwarding tasks of a large...
