A digital map/GPS based routing and addressing scheme for wireless ad-hoc networks

As intelligent transportation systems move towards advanced communication systems, it is fair to assume that every vehicle will be equipped with a digital map database, GPS receiver and 802.11 based radio in the near future. Ad-hoc networks by definition are infrastructure-less and are formed on the fly. Mobile nodes in the form of vehicles can effectively form ad-hoc networks. In this paper we present a routing algorithm and an addressing scheme for such a class of ad-hoc networks, which utilizes digital maps and the geographical position of the nodes. It can be shown that, for this class of ad-hoc networks the proposed scheme will outperform traditional MANET protocols.
