Position Based Routing in Vehicular Adhoc Networks – A Survey
A Vehicular Ad hoc NETwork or VANET is a novel approach of intelligent transportation system technology which has received significant attention recently. Routing in VANETs is a challenging task due to network partitioning, high vehicular speed and city environment characteristics. These characteristics results in degraded performance in traditional routing protocols. Traditional routing protocols, addressing the issues of Mobile Ad hoc NETwork (MANETs), are applicable for MANET applications. Position-based routing protocols, which are mostly based on greedy routing, are more suited to highly dynamic and mobile networks.
