摘　　要：针对网络速率分配的公平和堵塞减少问题,利用集成WiMax无线网络作为研究对象,提出一种自适应速率分配漏斗均衡调度算法。利用IEEE 802.16框架结构,建立由WiMax发射塔、中继站点、无线路由、用户站点、无线站点组成的WiMax无线基站集成网络;构建自适应流量共享方案,利用漏斗原理设计网络调度方案,兼顾网络调度的公平性和带宽利用率提升,给出吞吐量、平均延迟和有界延迟度量指标理论分析。通过实验验证了所提算法的有效性。Aiming at the problem of fairness and congestion reduction in network rate allocation, an adaptive rate allocation funnel equalization scheduling algorithm for integrated WiMax wireless networks was proposed. The WiMax wireless base station integrated network was established, which was composed of WiMax transmitter tower, relay station, wireless router, user station and wireless station using IEEE 802.16 frame structure. With the construction of adaptive traffic sharing scheme, the funnel de sign principle of network scheduling scheme was used, and utilization ratio was improved in terms of the network scheduling fairness and bandwidth, and the throughput, average delay and bounded delay metrics theory analysis were given. Experiments were carried out to verify the effectiveness of the proposed algorithm.
