A Qualitative Assessment of VANET Routing Protocols Under Different Mobility Models

Vehicular Ad-hoc Networks (VANET) is an advanced wireless network that came to increase traffic safety, efficiency and to improve driving experience. The high mobility of nodes is the major characteristic in these networks. The aim of this paper is to figure out the impact of various mobility models on the performance of Ad-hoc On-demand Distance Vector (AODV), Cluster-Based Directional Routing (CBDR) and Greedy Perimeter Stateless Routing (GPSR) protocols. In this study, we analyze the performance of these routing protocols in different mobility models namely: Street Random Waypoint (STRWP), Gauss Markov and Freeway having varying speed. The simulation results show that STRWP provides a good performance with the three routing protocols in terms of packet delivery ratio, throughput and end to end delay.
