Clustering techniques help to prolong the life of wireless sensor network, especially in hostile environment where battery replacement of individual sensor nodes is not possible after their deployment in the given target area. Clustering techniques also provide good load balancing, and in-network data aggregation. This paper introduces and analyzes a new clustering protocol in the wireless sensor networks based on energy band. The entire target area is divided into energy band which enables a node to estimate the energy with which it can transmit to the head node and head node to another head node towards a base station resulting in a prolonged life for the wireless sensor networks.
