Executive Summary

The objective of this paper is to increase life time of homogeneous Wireless Sensor Networks (WSNs) through minimizing long range communication and energy balancing. Sensor nodes are resource constrained particularly with limited energy that is difficult o r impossible to replenish. LEACH (Low Energy Adaptive Clustering Hierarchy) is most well -known cluster based architecture for WSN that aims to evenly dissipate energy among all sensor nodes. In cluster based architecture, the role of cluster head is very crucial for the successful operation of WSN because once the cluster head becomes non functional, the whole cluster becomes dysfunctional. The authors have proposed a modified cluster based WSN architecture by introducing a Coordinator Node (CN) that is rich in term s of resources.
