中文摘要：
提出一种自适应的实时轮询业务带宽分配机制，SS依据当前带宽需求和以往的实际分配带宽，提前预测实时业务数据包所需求的确切带宽，文中给出了数学分析模型和仿真，仿真结果表明，与传统的带宽分配机制和Mukul提出的自适应算法相比，该自适应带宽分配算法能更好地改善系统性能，提高吞吐量，减少时延和减少缓冲区需求．
英文摘要：
Proposed a novel bandwidth scheduling algorithm for real time polling services （rtPS）, the SS estimate the arrival of rtPS packets prior to the arrival and requests the BS for bandwidth in advance, based on the SS＇s request and the indeed bandwidth request by past. The analytical model and simulation show that, this adaptive algorithm provided better results with respect to the number of packets waiting at SS and average delay as compared to the widely accepted weighted scheduling algorithm and Mukul＇s adaptive bandwidth request mechanism.
