A Survey on Routing Protocols in VANET with Efficient Multicasting AODV Route Discovery

VANET is a Promising technology to improve the efficiency of inter vehicle Communications, for improving efficient road side Communication and safety between the vehicles, alerting vehicles by messages ,sharing between the vehicles, alerting vehicles by messages ,sharing the information and entertainments. Thus the vehicular Adhoc network (VANET) is a subclass of the mobile adhoc network (MANET) which is the emerging technology in intelligent transport system. The important factor for improving efficient communication is routing protocol in VANET. In this paper we will approach AODV protocol for better performance. The main aim of the paper is to propose a new protocol and algorithm for efficient message sharing by comparing the existing protocols and algorithm of VANET.
