Realistic mobility modeling for vehicular Ad Hoc networks

Abstract

The validity and performance of routing protocols for Vehicular Ad Hoc Net- works (VANETs) are mostly evaluated by simulations. However, simulations based on random mobility fail to consider individual and speci c behaviors of nodes. A realistic mobility model that is able to re ect some features of vehicle mobility is important for a more accurate evaluation. In this thesis, a realistic mobility modeling tool, Mobil- ity for Vehicles (MOVE), which considers the basic mobility behaviors of vehicles, is proposed. The proposed model is tested against the Random Waypoint (RWP) model using Ad Hoc On Demand Distance Vector (AODV) and Optimized Link State Rout- ing (OLSR) protocols to show that the mobility model can a ect the evaluation of a protocol signi cantly. Simulation results show that vehicle mobility model e ects the performance of routing protocols, emphasizing the importance of the mobility models in the evaluation of VANETs.
