An Energy Efficient Level Based Clustering Routing Protocol For Wireless Sensor Networks

Abstract

Nowadays advanced technology of Wireless Sensor Networks used in many applications like health, environment, battle field etc. The sensor nodes equipped with limited power sources. Therefore, efficiently utilizing sensor nodes energy can maintain a prolonged network lifetime. One of the major issues in sensor networks is developing an energy-efficient routing protocol to improve the lifetime of the networks. In this paper, we propose EELBCRP (Energy-Efficient Level Based Clustering Routing Protocol), a protocol for wireless sensor networks. Network partitioned into annular rings by using various power levels at base station and each ring having various sensor nodes. Also consider the residual energy of each node and distance from the BS of nodes as the principle of cluster-head election. The mathematical formulae for election the cluster head is provided. The model developed is simulated in MATLAB. The results are obtained in terms of three metrics-lifetime of the network, number of clusters and energy consumption of clusters heads. From the results of simulation, it is observed that the performance of EELBCRP is better in terms of energy consumption of CH, number of clusters and lifetime of network compared with LEACH.
