【摘要】：车载网络(VANET)具有节点高速移动,网络拓扑变化频繁,城市通信环境复杂,车载应用多等特点,这使得在真实场景下验证车载网络关键技术难度大,成本高,验证困难。因此,目前对车载网络研究成果的验证主要依赖仿真实验。车载网络的仿真主要包括交通仿真和网络仿真两个部分,其中节点移动模型的构建对于交通仿真来说尤为重要。交通仿真提供真实有效的车辆仿真场景,网络仿真提供通信协议以及对协议的性能分析,这两部分的技术发展都已相当成熟,但是将两者结合在一起能够适用于车载网络仿真的应用存在诸多问题,本文将重点研究移动模型和交通、网络仿真进行有机的结合。本文选用OMNeT++作为网络仿真器,使用SUMO作为交通仿真器生成真实的道路交通数据,选定车辆移动模型并结合车载网络路由协议在仿真平台上运行,收集日志数据,并对结果进行分析。本文的创新点是使用交通仿真器生成实时交通数据,结合地图生成了车载网络仿真的仿真场景,利用中间件技术对仿真数据进行日志记录,并完成协议的性能分析。通过仿真证明本文所选用的实验方法是有效的和正确的。
[Abstract]:The on-board network (VANET) has the characteristics of high speed moving nodes, frequent network topology changes, complex urban communication environment and many vehicle applications, which makes it difficult, expensive and difficult to verify the key technologies of vehicle network in real scene. Therefore, the verification of vehicle network research results mainly depends on simulation experiments. The simulation of vehicular network mainly includes two parts: traffic simulation and network simulation. The construction of node movement model is particularly important for traffic simulation. Traffic simulation provides real and effective vehicle simulation scene, network simulation provides communication protocol and performance analysis of protocol. However, the combination of the two can be applied to the application of vehicle network simulation, there are many problems, this paper will focus on the study of mobile model and traffic, network simulation for organic combination. In this paper, OMNeT is chosen as network simulator, SUMO is used as traffic simulator to generate real road traffic data, vehicle moving model is selected and vehicle network routing protocol is combined to run on simulation platform to collect log data. The results were analyzed. The innovation of this paper is to use the traffic simulator to generate real-time traffic data, combined with the map to generate the simulation scene of vehicle network simulation, using middleware technology to log the simulation data, and to complete the performance analysis of the protocol. The simulation results show that the experimental method chosen in this paper is effective and correct.
