Mobile Ad-hoc NETwork (MANET) is an infrastructure-less multi-hop network where each node communicates with other nodes directly or indirectly through intermediate nodes. Thus, all nodes in a MANET basically function as mobile routers participating in some routing protocol required for deciding and maintaining the routes. All these mobile nodes are battery operated. Hence, energy conservation is a critical issue in case of MANETs. The lifetime of a MANET depends on lifetime of its mobile nodes. Research is being carried out to conserve energy of mobile nodes at various levels, i.e., at the hardware level, operating system level and application level. Lot of work has been done to improve the energy efficiency of existing routing protocols for MANETs.
