LEACH-EO: A More Energy-Efficient LEACH Protocol for WSN

Abstract:

The sensor nodes in WSN are generally limited in energy, and the communication between nodes consumes most power. Therefore, it is the key point to reduce energy consumption and network traffic when designing routing protocols for WSN. The Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is a widely used and studied WSN routing protocol. In this paper, an improved LEACH based on energy-consumption optimization (LEACH-EO) was proposed against the deficiencies of LEACH. LEACH-EO implemented some improvements on the cluster-head selection of LEACH, meanwhile, the data redundancy of WSN was exploited to optimize the data transmission according to the characteristics of WSN. The simulation results show that LEACH-EO increases network lifetime and reduces energy consumption in comparison to LEACH.
