| 摘 要： | IEEE 802.16支持多种不同类型的调度服务,并将服务质量支持机制引入媒体接入控制层,却没有规定相应的调度算法。在IEEE 802.16定义的mesh模式下,针对不同类型服务,提出了一种区分服务的调度方案,该方案采用集中式和分布式混合调度。仿真结果表明:该方案下系统平均时延和用户满意度均有所改善。

| Abstract: | To meet the demands of subscribers,IEEE standard 802.16 provides QoS support to different traffic classes and introduces a supporting mechanism for quality of services(QoS)into medium access control(MAC)layer.But the corresponding scheduling algorithm is not prescribed.Considering the fact that different types of services with different delay and bandwidth constraints,a diff-service scheduling scheme is proposed.In the proposed scheme,hybrid scheduling with both centralized and distributed scheduling is used in WiMAX mesh network.Simulation results show that the average delay and the service satisfaction are improved. |
