【摘要】：车联网是物联网在智能交通系统的延伸,能够为人类的出行、生活带来更安全更便捷的体验。而车联网通信技术则是车联网的核心技术,是保证车和车之间组网的关键。就如人的耳朵和嘴一样,车联网通信技术,特别是制定的通信标准,使得原本一个个独立的车辆也拥有了“听觉”和“语言”能力,从而可以智能地相互协作相互协调。当前,美国的车联网WAVE标准则是目前世界上车联网通信标准中最为成熟开放的,已经出现了商业产品,并在很多车联网项目中被部署使用和验证。同时欧洲的车联网通信标准也在WAVE标准基础上做了进一步的扩展,并已在项目中部署了欧洲标准的原型。虽然我国的车联网工作已经开展多年,但是起步相对较晚,目前国内还没有出现相关标准,因此研究并借鉴美国WAVE标准的设计理念,有利于我国未来发展自身的车联网标准。为此,本文详细介绍了美国的WAVE标准,特别是其中的IEEE802.11p、IEEE1609.3和IEEE1609.4标准,并深入探讨了标准设计中的一些设计理念。同时,针对目前国外商业WAVE产品的价格昂贵且不能有效支持底层开发的问题,本文基于Linux系统和传统大功率无线网卡设计并实现了WAVE标准的初步原型,并实地验证了通信的可行性和互通性,实验表明数据可以在移动环境下快速无线通信。此外,针对研究工作中部分优化算法难以在实际环境下验证测试的问题,本文基于网络仿真器ns一3设计并实现了WAVE标准的仿真模型。同时基于该模型,本文还实现了三个不同仿真场景,有效地验证了WAVE标准对无线通信的影响。而且本文仿真模型和仿真场景的代码将开源使用,帮助其他研究者更好地研究和扩展。
[Abstract]:Car networking is an extension of the Internet of things in the Intelligent Transportation system (its), which can provide a safer and more convenient experience for human travel and life.Vehicle networking communication technology is the core technology of vehicle networking, which is the key to ensure the network between vehicle and vehicle.Just like the human ear and mouth, the communication technology of the car network, especially the communication standard, enables the original independent vehicles to have the ability of "hearing" and "language", so that they can intelligently cooperate and coordinate with each other.At present, the WAVE standard in the United States is the most mature and open in the world, and commercial products have emerged, and are deployed and verified in many vehicle networking projects.At the same time, the European vehicle networking communication standard has been further expanded on the basis of the WAVE standard, and the prototype of the European standard has been deployed in the project.Although our country's car networking work has been carried out for many years, it started relatively late, and there are no related standards in our country at present. Therefore, studying and drawing lessons from the design idea of American WAVE standard is beneficial to the future development of our country's own vehicle networking standard.Therefore, this paper introduces the American WAVE standard in detail, especially the IEEE802.11pWIEEE1609.3 and IEEE1609.4 standards, and discusses some design ideas in the design of the standard.At the same time, aiming at the problem that the foreign commercial WAVE products are expensive and can not effectively support the bottom development, this paper designs and implements the preliminary prototype of WAVE standard based on Linux system and traditional high-power wireless card.The feasibility and interoperability of the communication are verified in the field. The experimental results show that the data can be used in mobile environment for fast wireless communication.In addition, in order to solve the problem that some optimization algorithms are difficult to verify and test in the real environment, this paper designs and implements the simulation model of WAVE standard based on the network simulator NS-3.Based on this model, three different simulation scenarios are implemented to verify the influence of WAVE standard on wireless communication.Moreover, the code of simulation model and simulation scenario will be used in this paper to help other researchers to study and expand better.
