Ad-Hoc On-demand Distance Vector (AODV) is a stateless reactive routing protocol for Mobile Ad hoc NETworks (MANETs). To discover a route to a destination AODV relies on flooding technique which may result in unnecessarily large number of control packets traveling through the network and consuming such already scarce network resources as bandwidth, node processing power, and node battery power. This paper examines a new simple protocol for limiting the number of AODV control packets forwarded though the network during the route discovery process. The authors' approach, named GeoAODV, takes advantage of the Global Positioning System (GPS) and assumes that each communicating device has GPS access and knows its location.
