A mobile ad hoc networks (MANET) is a group of mobile wireless nodes which communicate without any fixed networking infrastructure. The nodes in an ad hoc mobile network are typically powered by batteries with a limited energy supply. For MANETs, One of the most important and challenging issues is how to conserve energy, maximizing the network lifetime.Since routing is an essential function in these networks, developing power-aware routing protocols has been an intensive research area in recent years. As a result, many power-aware routing protocols have been proposed from a variety of perspectives. In this article,we propose and analyse the model of power consumption in ad hoc network, present different power-aware metrics base on power consumption and survey some power-aware routing protocols proposed for mobile ad hoc networks.
