Abstract: Vehicular Ad-Hoc Networks [VANET] is one of the fastest emerging technologies for research as there are many issues and challenges to be addressed by the researchers before the technology becomes commercialized. The challenges in VANET are, designing suitable routing protocols appropriate to the traffic model, providing security of the data and emergency messages, avoiding the collision of messages, avoiding flooding of messages, etc. The progress of research in the field of VANET promises to deliver a robust, safety, efficient and intelligent transportation in the future. This paper gives the review of various Rebroadcasting policies in VANETs. The reason for analyzing the broadcasting protocols is that, in most of the emergency situations, there is less time to make a handshake with other nodes in the networks, as the emergency message is to be delivered fast and efficient. Therefore broadcast based routing protocol plays a major role in almost all the safety applications. A detailed understanding of the existing protocol is needed before contributing new protocol for the upcoming research field.
