Making MANET Energy Efficient

A recent trend in ad hoc network routing is the reactive on-demand philosophy where routes are established only when required. Most of the protocols in this category, however, use single route and do not utilize multiple alternate paths. This paper proposes a scheme to improve existing on-demand routing protocols by introducing the power aware virtual node scheme in whole scenario. The scheme establishes the multi paths without transmitting any extra control message. It offers quick adaptation to distributed processing, dynamic linking, low processing and memory overhead and loop freedom at all times. This scheme uses the concept of Power awareness among route selection nodes. It is done by checking power status of each node in the topology which insures fast selection of routes with minimal efforts and faster recovery. The scheme is incorporated with the Ad-hoc On-Demand Distance Vector (AODV) and Dynamic Source Routing (DSR) protocol and the performance has been studied through simulation.
