Abstract: VANETs (Vehicular Ad hoc Networks) are highly mobile wireless ad hoc networks and will play an important role in public safety communications and commercial applications. In VANET nodes which are vehicles can move safety with high speed and must communicate quickly and reliably. When an accident occurs in a road or highway, alarm messages must be disseminated, instead of ad hoc routed, to inform all other vehicles. Vehicular ad hoc network architecture and cellular technology to achieve intelligent communication and improve road traffic safety and efficiency. VANET can perform effective communication by utilizing routing information. In this paper, we have discussed about three greedy routing algorithms, and have compared to show which one is efficient in delivering packets in terms of mobility, nodes and transmission range.
Keywords: VANET, MANET, Routing Protocol, GNGR, ENGR, PDGR.
