VANET Simulation

Vehicular Ad-hoc Networks (VANET) are the subset of Wireless Ad-hoc networks specially introduced for the intelligent transportation system. It interconnects the massive range of vehicles in the distributed network. The main motive of Vanet Simulation is to increase vehicular interaction and driver safety in the case of undesired circumstances. Moreover, the VANET simulation comprises a mobility model and network simulator to analyze the simulated VANET model behaviour.
