Vehicular ad-hoc networks (VANETs) form when vehicles are equipped with devices capable of short-range wireless communication. Accurate simulation of VANETs is a challenging task, requiring both a vehicle mobility model and a network simulator. Although separate simulators exist, integrating them is difficult. We have developed an integrated simulator, based on studied, validated models. We argue that our simulator can be used for the studying of a large range of VANET protocols and applications, which would be very difficult to study by using other tools.
