Abstract
The vehicular ad hoc network (VANET) is a superior new technology. Vehicular ad hoc network (VANET) is a subclass of MANET that is mobile ad hoc networks. Vehicular ad hoc network provides wireless communication among vehicles and vehicles to roadside equipments. The communication between vehicles is more important for safety and more probably for entertainment as well. The performance of communication depends on how better the routing takes place in the network. Routing of data depends on routing protocols being used in network. The performance of routing protocols in vehicular ad hoc network (VANET) depends on different scenarios that are the city and highway. Position based routing protocols are best suited for vehicular environment. Furthermore, it also provides robustness in highly dynamic wireless ad hoc networks such as for VANET. The OLSR is best suitable for larger mobile network. It is having affecting factors like configuration, multipoint relays. The new automatic selection of optimal configuration can offer more enhanced performance. In proposed routing protocol the standard greedy approach is replaced with necessity first algorithm. Using proposed protocol the network traffic load of administrative packet is reduced. The proposed routing protocols are best suitable for vehicular network which are highly dynamic in nature.
