摘要
802.11-V2X作为车联网关键技术之一,以其技术成熟、安全系数高等优点,在欧美等国家得到了极大的关注与广泛的应用。本文以802.11p与802.11bd最新标准为核心,梳理出较为全面的802.11-V2X协议栈结构与技术演进路线,并分别解析了物理层与MAC层的原理机制,最后给出802.11-V2X系统架构的通用实现形式。
As one of the key technologies of the Internet of Vehicles,802.11-V2X has received great attention and extensive application in Europe,the United States and other countries due to its mature technology and high safety factor.This paper takes the latest standards of 802.11p and 802.11bd as the core,sorts out a more comprehensive 802.11-V2X protocol stack structure and technical evolution route,and analyzes the principles and mechanisms of the physical layer and the MAC layer respectively,and fi nally gives the structure of the 802.11-V2X system Common realization form.
