车载自组网是近年来无线网络以及智能交通领域的研究热点之一。在真实环境中测试和评估车载自组网的协议和应用有很大难度,因此利用车载自组网仿真工具进行研究就成为了一种很有效的技术手段。从车载自组网仿真的研究意义和研究内容出发,介绍了车载自组网仿真的发展历程和研究现状,对现有的车载自组网仿真器进行了分类,介绍和比较了典型的车载自组网仿真器,最后探讨了目前车载自组网仿真中存在的问题及未来的发展前景。
Vehicle ad hoc networks have the most remarkable aspects in the field of intelligent traffic in recent years. The field tests and evaluations of ad hoc networks protocols in real environment are much difficult, so using of vehicle ad hoe networks simulation tools has become a very effective technology. The meanings and contents of the vehicular networks simulation research were addressed. The development process and the status quo of vehicular ad hoc networks simulation were introduced, and then the classification and comparison of the typical vehicle ad hoc networks simulators were proposed, At last, the problems and the development trend of the vehicular ad hoc networks simulation were discussed.
