A mobile ad hoe network consists of wireless hosts that may move often. Movement of hosts results in a change in routes, requiring some mechanism for determining new routes. Seved routing protocols have hady been proposed for ad hoc networks. This paper suggests art approach to utitize location tifornration (for instance, obtained using the global positioning system) to improve performance of routing protmols for ad hm networks. By using location information, the propsed bcafion-Aided Routing (M) protocols limit the search for anew route to a smaller "request zone" of the ad hoc network. This results in a significant reduction in the number of routing messages. We present two dgorhhtns to determine the reguest zone, and rdso suggest potential Optitnizatiortsto our dgonthms.
Location Aided Routing (LAR) REF uses location information of sensor nodes to route packets in the network.
