VANET (vehicular ad-hoc network) is a classification of MANET in which vehicles act as mobile node and provides a different approach to Intelligent transport System (ITS). VANET is an emerging area for Intelligent Transportation System (ITS) which can result in increased traffic safety, collision warning through exchange of messages through wireless media. Efficient routing protocols are required for efficient communication among vehicles. In the given paper, we surveyed various VANETs protocols and along with its advantages and disadvantages. We compare our proposed protocols via NS-2 based simulations and show the performance of different protocols.
