Power aware metrics and routing techniques in MANETs

Mobile devices in Mobile ad hoc network are battery operated. Battery energy is an important resource in MANET nodes. This energy affects the communication actions in network. There are a lot of methods have been suggested to conserve energy at different layer of the network models; many techniques are proposed by different study. To provide the power aware routing methods an models, one must need to know about the metrics and protocols that can be used for power conservation. In this paper, the power consumption by nodes and power-aware routing metrics for power conservation has been discussed. Then, some protocols for preserving energy resources of mobile nodes and the design of Transport level protocols, capable of reducing the power usage of the communication devices have been described.
