A Comparitive Study of Data Forwarding Schemes in VANET

Abstract: VANET is a promising communication technology that enables communication among V2V and V2I for improving driving safety and efficiency. In VANET, data transfer is done with the help of multi-hop communication in which vehicles act as data carrier. Intelligent Transportations System (ITS) has deployed a no of RSU (Road Side Units) along the roads to collect and deliver traffic information from TCC (Traffic Control Centre) to the vehicles. This paper compares six vehicle trajectory-based data forwarding schemes, tailored for vehicular ad hoc networks. Nowadays GPS-based navigation systems are used for providing efficient driving paths for drivers. Subsequently it also discusses the performance of those data forwarding schemes and list the merits and demerits and conclude the challenges facing in the present day research in Vehicular ad hoc Network (VANET).
