【摘要】：以車路協(xié)同技術(shù)為研究背景,分析了現(xiàn)有短程通信技術(shù)和Wi-Fi接入認(rèn)證方案在高速動(dòng)態(tài)的行車環(huán)境中存在的問題,基于OpenWrt嵌入式Wi-Fi平臺提出了一種新的無線接入認(rèn)證方法,取消了傳統(tǒng)Wi-Fi通信的認(rèn)證、關(guān)聯(lián)機(jī)制,并對STA和AP信道進(jìn)行配置,實(shí)現(xiàn)了STA與AP的快速接入技術(shù),從而為車載單元與路側(cè)單元在Wi-Fi的覆蓋范圍內(nèi)相互通信節(jié)省時(shí)間。實(shí)際測試表明,該方法能較好地適應(yīng)移動(dòng)環(huán)境下的車輛通信。
[Abstract]:Based on the research background of vehicle-road collaboration technology, this paper analyzes the problems of the existing short-range communication technology and Wi-Fi access authentication scheme in high-speed and dynamic driving environment, and proposes a new wireless access authentication method based on OpenWrt embedded Wi-Fi platform. The authentication and correlation mechanism of traditional Wi-Fi communication is cancelled, and the STA and AP channels are configured. The fast access technology of STA and AP is realized, which saves time for vehicle-mounted units and road-side units to communicate with each other within the coverage of Wi-Fi. The experimental results show that the proposed method is suitable for vehicle communication in mobile environment.
