Review of Transmission Power Control Techniques in MANET

Now-a-days more and more devices are getting portable. In addition to device portability, MANET does not require a pre-established network infrastructure. As a result they can be deployed in situations like emergency rescue and disaster management. Nodes in MANET are run by battery power. Sometimes, it is difficult to replace and/or re-charge battery. Therefore, to increase the longevity of the network, the available battery power must be judiciously used. There have been various research activities in this area to increase the network lifetime. Different energy conservation techniques have been proposed by various authors. This paper surveys and classifies various energy aware routing protocols proposed in MANET. We present taxonomy of energy efficient routing protocol, their properties and design features. This paper aims to provide platform for those MANETs researchers in selecting appropriate routing protocol.
