Simulation and testing of VANET protocols

Dynamic network topology of VANETs (Vehicular Ad- Hoc Networks) brings challenges in designing various routing protocols. Common approach in testing of these VANET protocols is using the simulators that are able to simulate the real traffic environment and based on the simulation results protocols are evaluated. Currently, it is almost impossible to make experiments in real environment since the huge number of vehicles with computations and communication capability is needed. Implementation of these devices is expensive and complicated and it would be difficult to enable it on a large scale, with large number of vehicles in various conditions and environments. Therefore, we present several different VANET simulators and discuss possible method for easier and cheaper real world VANET experiments.
