Abstract: Vehicular Ad hoc Networks (VANETs) provide a promising approach for an Intelligent Information Transportation System. Several Routing protocols are used in VANETs for Communication in Vehicles to Vehicles (V2V) and Vehicles to Infrastructure (V2I) networks. These routing protocols for VANETs are classified as unicast, broadcast, and multicast. Based on this strategy VANET routing protocols are comparing using following parameters namely route discovery, forwarding strategy, no of transmission, etc.
Keywords: VANET, Routing protocols, topology based, position based, multicast based, broadcast based.
