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. The key distinction between VANET and MANET is the high mobility pattern, swift changing topology and capability of mobility prediction. However, it is not effective to apply the prevailing routing protocols of MANETs into VANETs. In this study, we are mainly focusing on significant features, summarizing the advancements of the VANET position-based routing protocols besides discussing the advantages and disadvantages of these routing protocols.
