摘要
车载自组网能有效提高道路交通的安全。安全信息传输是车载自组网最为重要的部分,安全信息快速、可靠传输需要设计有效的MAC协议。介绍VANET安全信息分类及相应MAC协议设计需求。对现有交通安全信息传输的MAC协议进行了综述。
Vehicle Ad hoc networks （VANET）is a vital component of intelligent transportation system（ITS）,which can improve the overall safety of vehicular traffic effectively. The safety message transmission is the most important application of VANET. It＇s necessary to design efficient medium access control （MAC） protocol to guarantee the quickness and reliability of safety messages transmission. This paper first introduces the VANET safety messages classification, and the requirements of designing MAC protocol. Then the existing MAC protocols are reviewed to understand traffic safety messages transmission.
