Wireless Sensor Networks (WSNs) have become an emergent new research area in the distributed computing environment. Sensor networks consist of embedded devices deployed in different types of environments in order to sense its surroundings. Communications amongst sensor nodes happen on a hop by hop basis. Multiple hops are formed to route data from a source node to a sink node or gateway. The main difficulty in sensor networks arises from the fact that nodes in sensor networks are resource and energy constrained. Additionally, these nodes may not have human intervention to replace batteries. The nature of these networks necessitates design requirements for energy efficient routing is critical. So AODV is standard routing protocol for wireless ad-hoc network.
