摘　　要：在移动自组网中,MAC协议是保证移动终端能够公平有效地共享无线信道所不可缺少的手段。近年来,随着车载通信系统的不断发展和自组网技术日益成熟,如何将二者有机结合成车载自组网已引起业界的极大关注。由于VANET自身的特点,以及其支持的业务应用种类非常丰富,现有自组网的MAC协议并不能直接用于VANET中。在简要介绍Ad Hoc网络中MAC协议的基础上,对VANET的MAC协议研究进展进行了综述,并指出了该领域的发展趋势。In mobile Ad Hoc networks （MANET）, MAC is indispensable to ensure that the mobile nodes fairly and efficiently share the wireless medium. With the development of vehicular communication systems and Ad Hoc network technologies, it has greatly attracted researchers in wireless community on how to combine them into vehicular Ad Hoc networks （VANET）. Since the specific characteristics and the increased variety of services in VANET, only few MAC protocols design for MANET can be adapted to VANET directly. The main MAC protocols for MANET are briefly introduced, and a survey of current MAC protocols for VANET is given. Finally, some future research areas for MAC in VANET are pointed out.
