摘　　要：链路的时变特征及节点移动的无规则性是造成移动Ad Hoc网络QoS保障难以实现的根本原因 .针对这一难题 ,本文在对INSIGNIA结构框架进行修改的基础上 ,通过增加动态资源调整、QoS路由及MAC层QoS保障等组件和机制 ,提出了一种新的自适应QoS结构框架MAQF .此外 ,本文还涉及移动接入时的QoS保障问题 ,并对动态资源调整算法进行了详细阐述 .仿真结果表明 。Providing QoS support for Mobile Ad-Hoc networks (MANET) will face a great deal of significant technical challenges under dynamic environment where time varying link and random mobility of nodes are two key characters. Through modifying the architecture of INSIGNIA and adding some components, such as QoS routing, DRA (Dynamic Resource Adaptation) and MAC QoS provisioning mechanism, a new framework MAQF that can overcome the disadvantages of related works and support QoS guarantees for MANET is presented. This paper also concerns mobile access QoS provisioning, and an explicit DRA algorithm. Simulation results show that MAQF fits the fluctuation of dynamic environment very well.
