Design and Evaluation of two Geocast protocols for Vehicular Ad-hoc Networks

Maria Kihl, Mihail Sichitiu, Harshvardhan P. Joshi


Vehicular ad-hoc networks (VANETs) offer a large number of new potential applications. One of the envisioned applications is of course Internet access, which can be provided with the help of some roadside basestations. Many of the applications benefit from multi-hop relaying of information, thus requiring a routing protocol. Characteristics unique to VANETs (such as high mobility and the need for geographical addressing) make many conventional ad hoc routing protocols unsuitable. In this paper we design and evaluate two different, so called, geocast protocols for VANETs.
One protocol is designed for fast communciation across a large area. The pupose of the other protocol is to provide a routing service for a future reliable transport protocol (enabling Internet applications). We evaluate the
performance of the protocols using realistic network and traffic models.
