【摘要】：車聯網是物聯網在智能交通系統的延伸,能夠為人類的出行、生活帶來更安全更便捷的體驗。而車聯網通信技術則是車聯網的核心技術,是保證車和車之間組網的關鍵。就如人的耳朵和嘴一樣,車聯網通信技術,特別是制定的通信標準,使得原本一個個獨立的車輛也擁有了“聽覺”和“語言”能力,從而可以智能地相互協作相互協調。 當前,美國的車聯網WAVE標準則是目前世界上車聯網通信標準中最為成熟開放的,已經出現了商業產品,并在很多車聯網項目中被部署使用和驗證。同時歐洲的車聯網通信標準也在WAVE標準基礎上做了進一步的擴展,并已在項目中部署了歐洲標準的原型。雖然我國的車聯網工作已經開展多年,但是起步相對較晚,目前國內還沒有出現相關標準,因此研究并借鑒美國WAVE標準的設計理念,有利于我國未來發展自身的車聯網標準。為此,本文詳細介紹了美國的WAVE標準,特別是其中的IEEE802.11p、IEEE1609.3和IEEE1609.4標準,并深入探討了標準設計中的一些設計理念。 同時,針對目前國外商業WAVE產品的價格昂貴且不能有效支持底層開發的問題,本文基于Linux系統和傳統大功率無線網卡設計并實現了WAVE標準的初步原型,并實地驗證了通信的可行性和互通性,實驗表明數據可以在移動環境下快速無線通信。 此外,針對研究工作中部分優化算法難以在實際環境下驗證測試的問題,本文基于網絡仿真器ns一3設計并實現了WAVE標準的仿真模型。同時基于該模型,本文還實現了三個不同仿真場景,有效地驗證了WAVE標準對無線通信的影響。而且本文仿真模型和仿真場景的代碼將開源使用,幫助其他研究者更好地研究和擴展。
[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.
