Routing Protocol for Wireless Sensor Network Based on Automatic Cluster Optimization

Abstract

The existing routing protocols such as LEACH and its improvements are all balance the overall energy consumption of the network by electing cluster heads looping and randomly. However, it also causes defects such as different cluster sizes and uneven cluster head distribution, resulting in uneven energy loss. In response to these shortcomings, this paper proposes a new routing protocol called AOCRP based on automatic optimization of clustering. The AOCRP has an optimized and fixed number of clusters, and the cluster head distribution is relatively uniform. It can adjust the number of nodes in each cluster automatically during the operation and keep the number of nodes the same in each cluster during each round. The AOCRP balances node energy loss and extends the life cycle of wireless sensor networks. Simulation experiments show that the performance of this protocol is better than EH-LEACH and DEEC in extending the network lifecycle and data transmission.
