【摘要】：车联网是通过车与车、车与路边基础设施等通信手段,实现对车辆的属性和状态信息进行提取和有效利用,从而为人民提供更加方便出行的服务。近年来,车联网的相关理论不断完善技术不断成熟,但一直缺乏足够的基础设施进行进一步的验证和研究。传统的交通仿真软件对于车辆和路网的仿真有着良好的效果,但是缺失通信仿真功能,也不能很好支持车联网研究成果的验证需求。本文在传统交通仿真软件TransModeler的基础上进行了二次开发,利用其提供的接口和事件机制,模拟了车联网中V2V通信的过程。系统将交通仿真与通信仿真结合起来,为车联网提供了有效的仿真验证工具。全文首先介绍了相关背景知识,并对TransModeler交通仿真软件的工作机制和开发方式,和V2V通信的工作模式进行了重点说明;然后分析了 V2V通信过程中的主要功能需求,设计了总体的模块划分;在各模块中,按照功能分布设计了主要的类的结构和方法,并完成了对于各个关键问题的处理的流程设计,实现了原型系统;对主要功能进行了测试,并通过应用案例验证了原型系统的可用性;最后总结了论文主要完成工作,并提出了进一步的工作方向。
[Abstract]:The vehicle network realizes the extraction and effective utilization of the attribute and status information of the vehicle through the means of communication between the car and the car, the vehicle and the roadside infrastructure, so as to provide the people with more convenient service to travel. In recent years, the related theories of vehicle networking have been matured, but there has been a lack of sufficient infrastructure for further verification and research. The traditional traffic simulation software has a good effect on the simulation of vehicle and road network, but the lack of communication simulation function can not support the verification requirements of vehicle networking research results. In this paper, based on the traditional traffic simulation software TransModeler, the secondary development is carried out, and the process of V2V communication in the vehicle network is simulated by using the interface and event mechanism provided by it. The system combines traffic simulation with communication simulation, and provides an effective simulation verification tool for vehicle networking. This paper first introduces the relevant background knowledge, and focuses on the working mechanism and development mode of TransModeler traffic simulation software, and the working mode of communication with V2V. Then the main functional requirements in the process of V2V communication are analyzed, and the overall module partition is designed. In each module, the structure and method of the main classes are designed according to the function distribution, and the flow design of dealing with each key problem is completed, and the prototype system is realized. The main functions are tested, and the availability of the prototype system is verified by an application case. Finally, the main work of the paper is summarized, and the further work direction is put forward.
