A new position based routing algorithm for vehicular ad hoc networks

The main requirement to make safer journey in VANET environment is minimum delay with high packet delivery rate. This ensures that all data packets are received with minimal delay to prevent any accident. This paper presents a new algorithm for VANET class routing protocol that covers sparse and coarse region of vehicles. It takes the advantage of road layout to improve the performance of routing in VANETs. The proposed algorithm uses real-time GPS tracking system to obtain traffic information for creating road based paths from source node to destination node. The optimize forwarding is used to figure out the forwarding node along the road pattern that form the path to deliver the data packets. The results shows that proposed algorithm obtain better results considering the various simulation parameters.
