Abstract

The invention discloses a wireless sensor network clustering method and system. The method comprises the following steps of: calculating the number of clusters of a wireless sensor network; selectingthe initial clustering center of k-means clustering algorithm by a region method, the initial clustering center being a cluster center; dividing nodes to be clustered in the wireless sensor network according to the number of clusters and the cluster center; judging whether the number of nodes in each divided cluster is within the threshold range; if yes, selecting a cluster head of each cluster; if not, adjusting the number of nodes in the cluster by splitting and merging; according to the cluster head and all nodes in the cluster, establishing data transmission routing, and completing clustering. The method and the system can make the clustering more uniform and the energy consumption of nodes in the network more uniform.

Description

technical field [0001] The invention relates to the field of wireless sensors, in particular to a wireless sensor network clustering method and system. Background technique [0002] Wireless sensor network (Wireless Sensor Network, WSN) is composed of a large number of miniature sensor nodes deployed in the monitoring area. The sensor nodes convert the monitored data into electrical signals and send them to the base station through wireless multi-hop communication. [0003] Routing protocols in wireless sensor networks include flat routing and hierarchical routing. The algorithm of the planar routing protocol is simple, and the energy consumption is relatively fast, so it is not suitable for use in large-scale networks. In hierarchical routing protocols, the network is usually divided into clusters, each cluster consists of a cluster head and multiple cluster members, and the cluster head communicates with the base station. Hierarchical routing is suitable for large-scale ...
