| 摘 要： | 仿真场景的构建对于车载自组网的性能具有很大的影响。在NS2网络仿真平台中添加了节点城区移动模型和存在障碍物时的无线信号传播模型,建立了VANET的网络模型,分别在三种不同场景中对DSR路由协议的性能进行了仿真分析。结果表明,在真实的仿真场景中VANET的性能有所恶化。达到了较为真实的仿真VANET的目的,得出的结论对VANET的仿真研究具有一定的参考价值。 |

| Abstract: | The setup of scenarios for simulation has great influence on the performance of the vehicular Ad hoc networks.The city section mobility model and the radio propagation model with obstacles is added in NS2，the network model of VANET is set up，and the performance of DSR is simulated and analyzed in three different scenarios.The result shows that the performance of VANET in more realistic scenario is worse.The paper has simulated VANET more realistically.The conclusion has some value in the simulation of VANET. |
| Keywords: | Vehicular Ad hoc Network（VANET） city section mobility model radio propagation model obstacle routing protocol |
