In this paper, the authors provide a summary of their research study of the location-aided routing protocols for Mobile Ad-hoc NETworks (MANET). This study focuses on the issue of using geographical location information to reduce the control traffic overhead associated with the route discovery process of the Ad-hoc On Demand distance Vector (AODV) routing protocol. AODV performs route discovery by flooding the whole network with the route request packets. This results in unnecessarily large number of control packets traveling through the network. In this paper, they introduced a new Geographical AODV (GeoAODV) protocol that relies on location information to reduce the flooding area to a portion of the network that is likely contains a path to destination.
