摘　　要：车辆自组网是智能交通系统的重要组成部分。安全控制与用户业务是车辆自组网最主要的两类消息,而两者不同的Qo S(Quality of Service)需求对车辆自组网MAC机制的设计带来了挑战。目前,多信道MAC机制是同时保障这两类消息不同Qo S性能的主要手段。首先介绍车辆自组网多信道架构标准IEEE 1069.4;其次从如何保证安全控制与用户业务这两类消息不同的Qo S需求入手,详细介绍了近年来基于IEEE 1069.4信道架构标准衍生的多信道MAC协议,并总结了目前相关工作的特点;最后,分析了车辆自组网多信道MAC机制的下一步研究方向。Vehicular ad hoc network is an important part of intelligent transportation system.Security control and user service are the two principal types of message,and the different QoS requirements for these two types of message would pose challenges to the design of vehicle self-organizing MAC mechanism.At present,the multi-channel MAC mechanism is the main means to simultaneously guarantee different QoS performances for these two types of message.Firstly,the multi-channel architecture standard IEEE 1069.4 for vehicle ad hoc network is described.Then,starting from how to ensure the different QoS requirements for security control and user service,the multi-channel MAC protocol based on IEEE 1069.4 channel architecture standard is presented in detail,and the characteristics of related work are summarized.Finally,the future research direction for multi-channel MAC mechanism of vehicle ad hoc network is discussed.
