【摘要】：以車路協(xié)同技術為研究背景,分析了現(xiàn)有短程通信技術和Wi-Fi接入認證方案在高速動態(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證方法,取消了傳統(tǒng)Wi-Fi通信的認證、關聯(lián)機制,并對STA和AP信道進行配置,實現(xiàn)了STA與AP的快速接入技術,從而為車載單元與路側單元在Wi-Fi的覆蓋范圍內相互通信節(jié)省時間。實際測試表明,該方法能較好地適應移動環(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.
