【摘要】：車(chē)聯(lián)網(wǎng)是物聯(lián)網(wǎng)在智能交通系統(tǒng)的延伸,能夠?yàn)槿祟?lèi)的出行、生活帶來(lái)更安全更便捷的體驗(yàn)。而車(chē)聯(lián)網(wǎng)通信技術(shù)則是車(chē)聯(lián)網(wǎng)的核心技術(shù),是保證車(chē)和車(chē)之間組網(wǎng)的關(guān)鍵。就如人的耳朵和嘴一樣,車(chē)聯(lián)網(wǎng)通信技術(shù),特別是制定的通信標(biāo)準(zhǔn),使得原本一個(gè)個(gè)獨(dú)立的車(chē)輛也擁有了“聽(tīng)覺(jué)”和“語(yǔ)言”能力,從而可以智能地相互協(xié)作相互協(xié)調(diào)。 當(dāng)前,美國(guó)的車(chē)聯(lián)網(wǎng)WAVE標(biāo)準(zhǔn)則是目前世界上車(chē)聯(lián)網(wǎng)通信標(biāo)準(zhǔn)中最為成熟開(kāi)放的,已經(jīng)出現(xiàn)了商業(yè)產(chǎn)品,并在很多車(chē)聯(lián)網(wǎng)項(xiàng)目中被部署使用和驗(yàn)證。同時(shí)歐洲的車(chē)聯(lián)網(wǎng)通信標(biāo)準(zhǔn)也在WAVE標(biāo)準(zhǔn)基礎(chǔ)上做了進(jìn)一步的擴(kuò)展,并已在項(xiàng)目中部署了歐洲標(biāo)準(zhǔn)的原型。雖然我國(guó)的車(chē)聯(lián)網(wǎng)工作已經(jīng)開(kāi)展多年,但是起步相對(duì)較晚,目前國(guó)內(nèi)還沒(méi)有出現(xiàn)相關(guān)標(biāo)準(zhǔn),因此研究并借鑒美國(guó)WAVE標(biāo)準(zhǔn)的設(shè)計(jì)理念,有利于我國(guó)未來(lái)發(fā)展自身的車(chē)聯(lián)網(wǎng)標(biāo)準(zhǔn)。為此,本文詳細(xì)介紹了美國(guó)的WAVE標(biāo)準(zhǔn),特別是其中的IEEE802.11p、IEEE1609.3和IEEE1609.4標(biāo)準(zhǔn),并深入探討了標(biāo)準(zhǔn)設(shè)計(jì)中的一些設(shè)計(jì)理念。 同時(shí),針對(duì)目前國(guó)外商業(yè)WAVE產(chǎn)品的價(jià)格昂貴且不能有效支持底層開(kāi)發(fā)的問(wèn)題,本文基于Linux系統(tǒng)和傳統(tǒng)大功率無(wú)線網(wǎng)卡設(shè)計(jì)并實(shí)現(xiàn)了WAVE標(biāo)準(zhǔn)的初步原型,并實(shí)地驗(yàn)證了通信的可行性和互通性,實(shí)驗(yàn)表明數(shù)據(jù)可以在移動(dòng)環(huán)境下快速無(wú)線通信。 此外,針對(duì)研究工作中部分優(yōu)化算法難以在實(shí)際環(huán)境下驗(yàn)證測(cè)試的問(wèn)題,本文基于網(wǎng)絡(luò)仿真器ns一3設(shè)計(jì)并實(shí)現(xiàn)了WAVE標(biāo)準(zhǔn)的仿真模型。同時(shí)基于該模型,本文還實(shí)現(xiàn)了三個(gè)不同仿真場(chǎng)景,有效地驗(yàn)證了WAVE標(biāo)準(zhǔn)對(duì)無(wú)線通信的影響。而且本文仿真模型和仿真場(chǎng)景的代碼將開(kāi)源使用,幫助其他研究者更好地研究和擴(kuò)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.
