Ad hoc network is a network without centralized administration in which different users can communicate and ex-change information. Mobile Ad-hoc NETwork (MANET) is a self configuring self organizing collection of mobile ad-hoc nodes with no fixed infrastructure. The node is free to move and the network topology changes rapidly. As the nodes in Mobile Ad hoc NETwork (MANET) have limited battery so power is always an issue in MANET. Power failure of node in MANET not only affects the node itself but also affects its ability to forward the data packet to the next hop and thus reduce the lifetime of network. In order to maximize the lifetime of the network energy consumption of each node must be controlled.
