| 摘 要： | 研究无线网络中实时业务的调度算法。介绍了几种常用的分组调度算法，提出了一种新的针对实时流式业务的调度算法，称为紧急门限比例延迟公平（UPDF，urgent-threshold proportional delayed fair）调度算法。实验结果表明，紧急门限比例延迟公平调度算法与其他分组调度算法相比，能够降低实时流式业务的分组丢包率并提高系统吞吐量，从而进一步使实时传输的要求得到满足。

| Abstract: | The scheduling algorithms of real-time services in wireless networks were researched in this paper.Some familiar packet scheduling algorithms were described firstly.Afterwards,a novel-scheduling algorithm for real-time streaming services was proposed,which was called urgent-threshold proportional delayed fair scheduling algorithm.By experiments,this new scheduling algorithm achieved lower ratio of losing packets and better performance of system throughput than other original scheduling algorithms.Hence,this algorithm can further meet requirement for real-time transmission. |
