Modeling mobility for vehicular ad-hoc networks

Without realistic modeling of node mobility, simulation evaluation of performance of mobile ad hoc networks may not correlate well with performance in a real deployment. In this paper, we propose a realistic model of node motion based on the motion of vehicles on real street maps. As a consequence, our model has the advantage of generating mobile scenarios that are unique to the geographical area that might be the target for the deployment of a mobile ad hoc network. We compare our model with the Random Waypoint mobility model, the most widely used mobility model. Results show that, in many ways, the Random Waypoint mobility model is a good approximation for simulating the motion of vehicles on a road, but there are situations in which our new model is better suited. Our mobility model can be used with the ns-2 simulator, thus making it easy for other researchers to use it for realistic simulation analysis.
