Accident Driver Model for Vehicular Ad-Hoc Network Simulation

Vehicular Ad Hoc Networks (VANETs) have been the research hotspot in wireless communication field recently. But implementing and testing applications or protocols in real world require prohibitive costs. Hence, most of the related researches depend on simulations. And mobility model is one of the most critical issues in the simulation study of VANETs. In this paper, we present a vehicular mobility model called ADM (Accident Driver Model) based on the concept of IDM (Intelligent Driver Model) to mimic the non-standard driver behaviors, and make the mobile nodes create accidents actively, while most of the mobility models don´t support this feature. Then we implement ADM on the open-source traffic simulator VanetMobiSim. Finally, we investigate the influences of different mobility models on the performance of VANETs routing protocol. The simulation results show that we can evaluate routing performance correctly with ADM.
