A vehicular ad hoc network is a collection of wireless vehicle nodes forming a temporary network. It can serve as a source of safe driving in near future. To make it successful, efficient routing protocols need to be used for communication among vehicles. This communication can be done directly within vehicles with the help of Road Side Units (RSUs) or without using centralized RSUs. This paper explores the GPSR, ASTAR and BMFR position based routing protocols based on their performances with respect to different metrics such as throughput, end to end delay and number of packets drops during communication.
