Low Energy Consumption Cluster-Based Routing Algorithm for Wireless Sensor Networks

Abstract

In this paper, we investigate the problem of how to conserve energy for the wireless sensor networks. By analyzing LEACH protocol and LEACH-C protocol, we proposed a new algorithm, Low Energy Consumption Cluster-Based Routing Algorithm (LECCBRA) to overcome the shortcomings of LEACH, LEACH-C protocols in cluster head selection and communication between cluster heads and base station. Compared to LEACH, LECCBRA protocol provides improvements in the selection of the next head cluster, re-partition of network and inter-cluster routing. Simulation results show that the total energy can be effectively saved, and the balance in energy consumption between clusters can be achieved with LECCBRA, thus the network lifetime is extended.
