Simulation is the predominant tool used in research related to vehicular ad hoc networks. This paper first presents the key requirements for accurate simulations that arise from the various applications supported by VANETs, and review the current state-of the-art VANET simulation tools. The authors then present VGSim, an integrated networking and microscopic vehicular mobility simulation platform. VGSim provides full-fledged wireless network simulation with an accurate traffic mobility model.
