The emergence of wireless communication and transportation through inter vehicular communication has promised countless applications enhance the overall driving experience. Vehicular communication would require efficient routing protocols, secure communication, proper coverage and standards.Various routing protocols have been adapted for VANET and particularly using position based routing approach. The paper gives an overview of position based routing protocols and compare them in the context of driving experience and safety. Key words: VANET Position Protocols INTRODUCTION have to be designed with high mobility and ensure the The Vehicular Ad hoc networks have received much road intersections, obstacles and road patterns of attention for the development of traffic safety as well as specific area restrict the vehicles movement in ensuring a pleasant driving experience in transportation network. The routing protocols use these information for sector. VANET can provide a wide range of user services route decision and forwarding the packet between source with the use of communication devices without prior to destination. infrastructure. The use of Ad hoc in this network was deemed the most suitable method [1]. The vehicles are Position Based Routing Protocols: The distinctive moving on the roads, equipped with wireless features of VANET a different and efficient routing communication devices and interlink with each protocol required for communication. The position based other.Various routing protocols have been proposed for approach in protocols proposed for different projects efficient routing between vehicles and categorized into such as FleetNet [2], CarTALK2000 and NoW [3-4]. different types such as topology, position, broadcasting, Position based routing protocols requires physical beaconing, hybrid etc. In position based routing position of vehicles in network for perform data protocols the navigation system GPS is using to perform routing. Global positioning system (GPS) use for communication by utilizing position information of vehicle position information in network. Some other strategies in network. On the contrary, topology based routing are used in these protocols such as beaconing, location protocols alleviate the problems of scalability or control services, forwarding and recovery strategies. The first message overhead. Various issues of VANET are beaconing strategy is use for contain the neighbor being looked into like routing protocols, security, vehicle node position and location services obtain applications and much more. the destination location. In forwarding and recovery, One of the main challenge is designing efficient strategies are used for packet forwarding between routing protocols for data delivery between vehicles source and destination nodes.The position based because the traditional Ad hoc routing protocols are not routing protocols have many advantages such as no need suitable for VANET. The vehicles are moving with high route maintenance and routing path determined when range of speed and network topology change more packets are required to be forwarded. These protocols rapidly that causes frequent network fragmentation and only need position information of destination, node packet dropping in network. Therefore, routing protocols identifiers, forwarding nodes and their neighbors. reliability of safety related applications. Traffic lights,
