摘要： 提出了一种适用于无线分组网络的混合分组调度策略.该混合分组调度策略采用有线网络中WF2Q(worst-case fair weighted fair queuing)算法和无线网络中C-IFQ(channel-condition independent packet fairqueuing)算法相结合的方式,针对不同类型的分组业务进行分组调度.仿真结果表明,在无线网络中该策略保证了资源的公平调度,并在保证资源的有效利用与延迟的同时,还具有良好的长期公平性与短期公平性.

Abstract: An integrated strategy of packet scheduling is proposed which is suitable to wireless networks. The strategy combines the WF2Q (worst-case fair weighted fair queueing) algorithm for wired network with the C-IFQ (channel-condition independent packet fair queuing) algorithm for wireless network together to do packet scheduling with different type of sessions sorted out. The result of simulation indicates that it can guarantee packet delay, efficient utilization of bandwidth and long/short-time fairness when scheduling.
