LOCATION UPDATION FOR ENERGY EFFICIENT GEOGRAPHIC ROUTING IN MANET

B.Manimegalai, D.Geetha

Abstract: Routing in mobile ad-hoc networks with a large number of nodes or with high mobility is a very difficult task and energy conservation is very important for mobile devices. In geographic routing each node require information about neighbors to forward data packets. Earlier periodic updations are used for location updation but it consumes much amount of node energy and bandwidth utilized for unnecessary updation where there is no changes in the location information. In this paper adaptive position update used with less energy consumption and utilize the bandwidth for location updation only when there is a change in the network. The GPSR protocol used for packet forwarding in both greedy forwarding and perimeter forwarding. This adaptive updation utilize only less amount of node energy than other beaconing scheme.

Keywords: Routing protocols, Beacon updation scheme, Wireless communication, Greedy forwarding, Adaptive position updation.
