Comparative Study Of Various Routing Protocols For Vehicular Ad Hoc Networks (VANET)

Abstract
Vehicular Ad Hoc Network (VANET) uses mobile ad hoc network (MANET) for the implementation of the technology. VANET is used for communication between the vehicles to avoid accidents or the traffic jam occurring during the collision and various other information can also be communicated between the vehicles based on the required applications. Warning message to other vehicles can be broadcasted by the use of VANET technology to control the collision. Based on the performance the protocol for the increased number of vehicle on the road is proposed. In this paper the comparative study of all the protocols is presented. With focus on Position based routing protocol for VANETs. In this protocol, it is assumed that all vehicles are provided with Global Positioning System (GPS) in order to know the locations. Protocol uses restricted GPRS protocol to transfer a data packet and for recovery, carry and forwarding strategy will be used. Both the vehicle-to-vehicle (V2V) and vehicle to-RSU (V2R) communication is considered. All the crossing point on the roads have an RSU (Road Side Unit) which takes all the conclusions that decides in which path the data is transmitted. If no suitable path is found, then the RSUs will store the data packet until they find the suitable way to transmit the data packet. The paper focuses on the novel routing protocol which will be used in the VANET system. The proposed protocol stretches the new development for communication among the vehicles. During emergencies the cost effective VANET technology plays a vital rule. Keywords - VANET,GPRS, MANET
