POSTER: Enhancement of Cluster-Based Routing Protocol in Wireless Sensor Network

Abstract

The challenges of wireless sensor networks include the unsafe condition of power resources for prolonging network lifetime. Low-Energy Adaptive Clustering Hierarchy (LEACH) protocol is a solution for efficient energy consumption in sensor networks, which chooses the cluster head randomly. Therefore, this paper not only tries to improve the cluster head selection process by considering the predefined radius of base station or sink node to choose the gateway nodes as relays, but also considers a sleep/awake cycle for the purpose of reducing the energy consumption. The enhanced protocol, namely E-LEACH is expected to reduce energy consumption and prolong the network lifetime for the sensor networks.
