A Energy-Efficient Clustering Routing Algorithm Based on Distance and Residual Energy for Wireless Sensor Networks

Abstract

Aiming at the problem of limited energy of sensors in Wireless Sensor Network, based on the classic clustering routing algorithm LEACH, a distance-energy cluster structure algorithm considering both the distance and residual energy of nodes is presented in the dissertation, which improves the process of cluster head election and the process of data transmission. It reduces the adverse effect on the energy consumption of the cluster head, resulting from the non-uniform distribution of nodes in network and avoids the direct communication between the base station and cluster head, which may has low energy and far away from base station The results of simulation indicate that the improved algorithm effectively balances the energy consumption, prolongs 31% of the lifetime, reduces 40% of the energy consumption and has a better performance than the original LEACH protocol.
