A Clustering Routing Algorithm for Extending the Lifecycle in WSN

In order to extend the life of wireless sensor networks and improve the stability of wireless sensor networks, a cluster head election mechanism based on energy center of gravity and regional segmentation is proposed. The sensor network monitoring area was divided into finite subregions, and the common nodes of each subregion competed for cluster heads in their own regions, which made the distribution of cluster heads in the whole network more uniform. Each sub-region node is selected for the cluster head based on two factors: energy center and communication distance. The cluster head is responsible for receiving the data perceived by ordinary nodes in the region, and the received information is fused and compressed and transmitted to the base station, thus solving the problems of uneven cluster head distribution and unbalanced node energy loss in the clustering algorithm. The simulation results show that compared with the traditional LEACH clustering algorithm and the improved LEACH-M algorithm, the new algorithm can achieve the purpose of balancing the energy loss of each node, effectively reduce the overall energy loss of the sensor network, and thus extend the network life cycle.
