A Road Selection Based Routing Protocol for Vehicular Ad Hoc Network

Vehicular ad hoc network is an advanced wireless communication technology to provide intelligent transportation system services to the drivers and passengers. High mobility of vehicles in the network creates gaps between the vehicles, which reduces the performance of the system. If network gaps in a path are predicted earlier before sending the data, then the performance of the system increases. In this paper, a novel position based routing protocol is proposed to send the data quickly from the source to the destination. This is performed by selecting a best road from a junction to the neighbor junction. The road is selected by calculating road ratings for each road connected to the junction. A recovery method is proposed to connect the vehicles which suffers from the network gap problem by adjusting the speed of the sufferer vehicles. Simulation results show that, proposed method performs better than P-GEDIR, GyTAR, A-STAR and GSR routing protocols in terms of average end-to-end delay, network gap encounter and number of hops.
