中文摘要：
提出了一种基于预测的自适应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，对实时业务数据包所需求的确切带宽进行预测并调度．给出了数学分析模型和仿真，结果表明，与传统的带宽分配机制相比，该自适应的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，减少缓冲区需求．
英文摘要：
In this paper we propose 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, and then schedule the packets. 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.
