A Novel Cluster Head Selection Algorithm Based on Energy Consumption for LEACH

Abstract:

Wireless sensor networks are widely deployed in various areas of our daily life. The lifetime of wireless sensor networks takes significant effect in the performance of the whole network. Many network protocols are proposed to improve the lifetime of networks, and among them, low-energy adaptive clustering hierarchy (LEACH) is a promising protocol with self-organization of the clusters and periodic rotation of cluster heads selection to distribute energy consumption uniformly. LEACH performs well compared with other protocols on lifetime while it is simplified and has aspects to improve. In this paper, we modified the procedure of cluster heads selection in LEACH and proposed a protocol LEACH-CHE with consideration on the energy consumption of cluster heads. We analyzed LEACH-CHE and with the results of simulations, LEACH-CHE over performs on network lifetime compared with the original LEACH.
