Energy Efficient Hierarchical Clustering Routing Protocol for Wireless Sensor Networks

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 EEHCRP (Energy-Efficient Hierarchical 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. The mathematical formulae for choosing the cluster head are provided. The model developed is simulated in MATLAB. The results are obtained in terms of three metrics, lifetime of the network, and number of clusters and energy consumption of clusters heads. From the results of simulation, it is observed that the performance of EEHCRP is better in terms of energy consumption of CH, number of clusters and lifetime of network compared with LEACH.
