Executive Summary

In Wireless Sensor Network, dynamic cluster based routing protocol is mostly used. It is a network of battery operated, tiny, mostly homogeneous sensor nodes having limited memory, processing power with wide applicability in the area of military, weather forecasting etc. As it is battery operated, it requires energy awareness in all layers of the networking protocol stack to prolong the life time of the network. Protocol designed for such sensor network must efficiently use limited bandwidth and energy of the sensor node.
