摘　　要：要实现移动Ad Hoc网络MANET民用化 ,必须解决其MAC层的QoS保障问题。MAQF/MAC是一种新的MANET自适应QoS介质访问控制策略 ,该策略可以实时动态地测试网络资源 ,及时调整业务流对资源的访问和占用。本文着重从仿真实现角度 ,对MAQF/MAC协议的原理、预留表结构、QoS路由、压缩算法等问题进行探讨。仿真结果表明 ,MAQF/MAC在资源利用率和分级服务的QoS保障能力等方面明显优于MACA/PR。In order to adapt MANET for civil use, QoS provisioning for MANET at MAC layer should be provided. MAQF/MAC is a new adaptive MANET QoS supporting MAC protocol, which can dynamically measure the variation of resource in real time, and change the channel access policy and the amount of resource captured by traffic. From the standpoint of simulation, this paper mainly concerns some key components of MAQF/MAC including work principle, resource table, QoS routing, compression algorithm and etc. Simulation results show that MAQF/MAC is superior to MACA/PR in the aspect of multi level traffic QoS guarantees and resource utility.
