Abstract
A Vehicular Ad hoc Network or VANET is a novel approach of intelligent transportation system technology which has received significant attention recently. The model of the routing protocols used in VANETs is very vital for enhancing the safety of the drivers, regulating traffic and improving the whole driving experience. VANET is a type of mobile ad hoc networks (MANETs). 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. Some researchers had contributed a lot in the area of VANET. 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.
