Mobile Ad-hoc NETwork (MANET) is infrastructure less network. MANET consists of randomly deployed nodes connected by various links. Important issues in MANET are link failure, power failure of node, limited bandwidth, and limited transmission power. To overcome these problems energy efficient protocol has become a very interesting and important research area. To improve network lifetime, energy balance is an important concern in MANET. In this paper, the authors investigate the different protocols proposed to resolve the issue of energy consumption of routing nodes in MANET.
