Mobile ad hoc network is a compilation of wireless mobile terminals that are in contact with each other in the absence of a permanent infrastructure network. This gives an irregular formation. Many resources like power, energy, reliable data delivery and end to end delay plays a significant role in the network. But due to the dynamic movement of nodes, power management and energy conservation stands as a critical area. This is also due to the limited battery power and the maximum utilization of power by the nodes in the network .The responsibility of saving power has increased and it is possible by minimizing the consumption during the routing process. It is done in order to expand the lifetime of the network.
