The recent advancement in wireless technology and car industry has created wireless communication between vehicles which is known as VANET (Vehicular Ad hoc NETwork). VANET provides mobility to vehicles as smart vehicles can communicate with one another and prevent many accidents. Multihop wireless connectivity and frequently changing network topology in VANET are the factors that motivate to design efficient dynamic routing protocols. In this paper, various routing protocols are discussed and comparison based on various parameters such as loop free path, multicast capability, multiple route possibility, routes maintained, table expiration timers, route reconfiguration methodology and periodic routing advertisement has been presented.
