MANET is collection of mobile nodes that form a network independently of any centralized administration. Since those mobile devices are battery operation based and extending the battery lifetime has become an main aim. Generally all the researchers have recently started to consider power-aware development of efficient protocols for MANETs. When each mobile node in a MANETs performs the routing function for effective establishment of communication among different mobile nodes the “Death” of even an any of the nodes due to power exhaustion might cause disconnect of services in the entire MANETs. So, mobile nodes in MANETs are battery based. Thus, they affect from limited energy level problems. When the nodes in the network are moving if a node moves out of a radio range of the other node then link between them is broken. Mainly due to this environment there are two major conditions of a link break that is Node dead due to energy collapse and Node going out of the radio range of its adjacent node [1].
