【摘要】：車載網絡(VANET)具有節(jié)點高速移動,網絡拓撲變化頻繁,城市通信環(huán)境復雜,車載應用多等特點,這使得在真實場景下驗證車載網絡關鍵技術難度大,成本高,驗證困難。因此,目前對車載網絡研究成果的驗證主要依賴仿真實驗。車載網絡的仿真主要包括交通仿真和網絡仿真兩個部分,其中節(jié)點移動模型的構建對于交通仿真來說尤為重要。交通仿真提供真實有效的車輛仿真場景,網絡仿真提供通信協議以及對協議的性能分析,這兩部分的技術發(fā)展都已相當成熟,但是將兩者結合在一起能夠適用于車載網絡仿真的應用存在諸多問題,本文將重點研究移動模型和交通、網絡仿真進行有機的結合。本文選用OMNeT++作為網絡仿真器,使用SUMO作為交通仿真器生成真實的道路交通數據,選定車輛移動模型并結合車載網絡路由協議在仿真平臺上運行,收集日志數據,并對結果進行分析。本文的創(chuàng)新點是使用交通仿真器生成實時交通數據,結合地圖生成了車載網絡仿真的仿真場景,利用中間件技術對仿真數據進行日志記錄,并完成協議的性能分析。通過仿真證明本文所選用的實驗方法是有效的和正確的。
[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.
