Wireless Ad hoc network is a combination of nodes that move freely and communicate with other nodes in wireless network. Most of the nodes may be identical in their capabilities, but some nodes are selected to form the backbone of wireless network. These nodes are known as clusterheads. The wireless backbone can be used either to route packets, or to disseminate routing information, or both. Nodes of ad hoc wireless networks are powered by batteries due to their mobility. Communications cause the batteries to be discharged. Clusterhead batteries discharged soon as compared to other nodes in the wireless adhoc networks due to their high involvement in communication within the cluster.
