中文摘要：
无线移动Ad Hoc网络（MANET）作为可移动分布式多跳无线网络，没有预先确定的网络拓扑或网络基础设施以及集中控制。由于移动Ad Hoc网络的动态性和资源的限制，在如此的网络中提供QoS保障是一个挑战性任务。Ad Hoc网络的分组优先级调度算法将增进网络的性能。提出了一个基于模糊控制的Ad Hoc网络QoS优先调度算法，用于决定Ad Hoc网络中分组的优先级。利用NS2仿真软件对分组的传输率、平均端对端的延迟等做了性能分析，仿真结果表明，该方法高效、可行，可应用于Ad Hoc网络。
英文摘要：
Mobile ad hoc network （MANET） is an autonomous system of mobile wireless nodes connected dynamically without any preexisting infrastructure. Quality of Service （QoS） requirement in networks with uncertain parameters has become a very important research issue in the mobile ad hoc networks. The multi hop wireless forwarding of packets, broadcasting of control traffic and the fact that, all nodes may act as routers in addition to being sources and sinks of data in ad hoc networks produce different queuing behavior. Hence, a scheduling algorithm for scheduling the packets based on their respective priorities will improve the performance of the network. This paper presents a fuzzy QoS controller based priority scheduler for mobile ad hoc networks to determine the priority of the packets. The performance of this scheduler is studied using NS2 and evaluated in terms of quantitative metrics such as packet delivery ratio, average end - to - end delay and throughput. Simulation shows that the approach is efficient, promising and applicable in ad hoc networks.
