摘　　要：Ad hoc网络的应用环境以及与Internet的互连要求它必须提供一定的服务质量(QoS)保证,然而,无线信道固有的特点及节点移动造成网络拓扑的频繁变化,使得在Ad hoc网络中支持QoS面临许多新的挑战。首先介绍了Ad hoc网络中提供QoS保证的各种困难,然后详细讨论了动态服务质量保证机制以及具有QoS能力的中间适配机制,接着介绍了支持QoS的MAC协议,并指出了亟待解决的问题和今后的研究方向。In Ad hoc network environment, as well as interconnection with the Intemet, it must provide a certain service quality （QoS） guarantees, however, the wireless channel inherent characteristics and node movement caused by the frequent changes of network topology make the Ad hoc network to support QoS face many new challenges. This paper first introduces the various difficul- ties to guarantee QoS in Ad hoc network, and then discusses in detail the dynamic quality of service assurance mechanisms and QoS capabilities between the adaptation mechanism, then introduces the MAC protocol to support QoS, and points out the question which urgently need to be solved and future research direction.
