Geocast enhancements of AODV for vehicular networks

Abstract

Because of its reactive nature, AODV can handle the highly-dynamic behavior of vehicular Ad-Hoc networks relatively efficiently. However, in addition to link status information, a lot of other information is available within cars, e.g. information about speed and location as well as digital maps. The realization of some of the envisioned application scenarios depends on the additional usage of this information. In this paper, we motivate the usage of GPS- and vehicle velocity data for geocast applications in the vehicular environment. We also describe the prototype that we are developing based on NIST-AODV [4].
