摘　　要：Ad hoc网络中的QoS保障问题是一个比较复杂的开放问题。本文首先介绍了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协议和其它一些相关的QoS保障机制,最后讨论了QoS的衡量尺度和QoS路由,并给出了结论。The problem of guaranteeing QoS in Ad hoc network is a complicated open issue. This paper firstly introduces various difficulties in providing QoS in Ad hoc network. Then the dynamic QoS guarantee mechanisms and QoS aware middle adaptation schemes are discussed in detail. Afterwards, a MAC protocol which can support QoS and some related schemes are introduced. Finally, metrics that can evaluate QoS and QoS routing are discussed and some conclusions are given.
