Simulation of VANET in a More Realistic Scenario

Scenarios for simulation are important for the performance of the Vehicular Ad hoc Networks. The paper proposed a more realistic scenario-the City Section Mobility Model and the Radio Propagation Model with Obstacles. They were added in NS2, and the performance of the routing protocol was simulated in the traditional scenario and the new one. Then the performance of DSR and AODV is simulated and analyzed in the new scenario. The result showed that in the more realistic scenario AODV is more suitable for VANET. The paper has simulated VANET more realistically. The conclusion has some value in the simulation of VANET.
