摘要 针对IEEE 802.16e协议的特点,提出了一种基于最小速率保证的IEEE 802.16e公平调度(MTRFS)算法。算法支持多种业务流类型并可保障业务流的最小预约速率。该算法中引入了补偿模式,以保障处在恶劣信道条件下的业务流的最小速率。同时,该算法对高级别业务流和信道条件好的业务流提供尽可能多的带宽,以保障其QoS性能和系统吞吐量的最大化。仿真表明,该算法能够保证业务流的最小预约速率,区别对待不同优先级的业务流;无论是其公平性能还是吞吐量性能都优于传统的PF算法。该算法与IEEE 802.16e协议很好的结合,具有很强的实用价值。 According to the characteristics of IEEE 802.16-2005, a minimum reserved traffic rate based fair scheduling algorithm in IEEE 802.16-2005 is proposed in this paper. It can support multiple service types and guarantee every service＇s minimum reserved traffic rate. A compensation strategy is introduced to ensure minimum reserved traffic rate of service which is in bad channel condition. At the same time, services which have higher priority and are in good channel condition are granted more bandwidth to ensure the QoS （quality of service） and maximize the throughput performance. The simulation study shows that the algorithm can guarantee the minimum reserved traffic rate and distinguish the services in different levels. Furthermore, the algorithm has advantages in both fairness and throughput performance compared with PF （proportional fair） algorithm. The algorithm proposed in this paper is in accordance with IEEE 802.16-2005 and has great value.
