[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.
