宽带无线因特网络中的加权轮循调度算法

Weight Round Robin Scheduling Algorithm in Broadband Wireless Internet Network

无线分组调度是保证无线多媒体业务服务质量的一个重要方面 .针对码分多址 ( CDMA)传输模式 ,对可变速率实时业务 ( VBR)的调度策略进行改进 ,提出了一种基于传输速率的无线调度算法 .仿真结果表明 ,该调度算法在满足各业务服务质量的同时 ,保证了各服务之间的公平性 。

Wireless packet scheduling is an important aspect to support the multimedia quality of service. This paper proposed a scheduling algorithm based on transmission rate that is suitable for CDMA model, adopting weight round robin algorithm for variable real timeservice, such as VBR. The simulation shows that this kind of algorithm will guarantee QoS and ensure the fairness of each service. It can compensate the error of wireless link.
