This paper presents a survey on the art of energy efficient routing protocols for Mobile Ad-Hoc NETwork (MANET). Since the nodes in MANET are mobile, the routing and power management become critical issue. In this widely used field, considering both protocols and analytical frameworks for efficient energy routing. The main focus on motivation, research challenges, recent development and modifications in existing straight routing protocols to make them as energy efficient. Moreover, the latest development, industry effort and the future directions for further research are identified.
