摘　　要：WiMAX Mesh网络资源调度可以分为集中式调度和分布式调度。对于集中式的资源调度,在图染色算法和PMP调度算法的基础上,提出了保证QoS的自适应资源调度算法。该算法在确定资源调度顺序时,采用了业务流拓扑信息、业务流服务质量满意度以及业务流优先级等参数。对rtPS的业务丢包率、nrtPS的业务吞吐量和系统的吞吐量等参数进行了仿真对比,结果显示自适应能源调度算法能够根据实际的需要更加灵活地满足QoS需求。WiMAX Meshnetwork resource scheduling canbe divided intocentralized and distributedscheduling. Onthe basisof the graph coloringalgorithm and the PMP scheduling algorithm, an adaptive resource scheduling algorithm for QoS is proposed for centralized resource scheduling. The algorithm adopts the parameters of topology information of business flow, satisfaction of service quality and business flow priority when determining the sequence of resource scheduling. The simulation comparison of rtPS's packet loss rate, nrt PS's traffic throughput and system through put are conducted. The results show that the adaptivere source scheduling algorithm can meet QoS's needs more flexibly according to actual needs.
