Title: Position-Based Routing in Ad-Hoc Wireless Networks
Published: In Mohammad Ilyas (ed.): The Handbook of Ad Hoc Wireless Networks, CRC Press, Boca Raton, FL, U.S.A., 2002
Abstract: In ad-hoc networks, autonomous nodes collaborate to route informationthrough the network. Commonly, nodes are end-systems and routers atthe same time. In case nodes have a notion of their geographicposition, a position-based routing protocol can be used, whoseproperties of statelessness and fast adaptability to changes in thetopology match very well with the characteristics of ad-hoc networks.Position-based routing does not require the maintenance of routes butforwarding decisions are made locally, based only on the node's ownposition, the positions of its neighbors and the position of thedestination. The routing algorithm is complemented by a locationservice through which a node can obtain the position of a packet'sdestination.We will introduce components of position-based routing, discuss someof the previously published routing algorithms, and present anapplication scenario where position-based routing can be used forinter-vehicle communication.
