摘要 研究了基于WLAN访问Internet的网络基站处流,提出了一种基于队列长度的调度方法和基于信道容量的拥塞控制模式,以达到网络资源的公平分配,并解决由于不恰当处理基站处堆积数据包而引起的弊端。在提出的资源分配模型中,调度算法根据各条流堆积的队列长度来随机地选择将要发送的数据分组;而拥塞控制模式中,将链路使用率作为拥塞指示,通过计算,平等地反馈给每一条流的发送端。发送端根据反馈到的拥塞信息来调整发送速率,以达到资源分配的公平性。仿真的结果表明:各条流能公平地共享无线网络的带宽。此算法的最大的优点在于基站不需要按照某种特定的公平性定义来选择数据包却能达到很高的公平性。 In this paper,focusing the attention mainly on the downlink traffic,the authors presented a scheduler based on queue length at base station and a congestion control scheme based on the wireless channel.The scheduler scheduled flows proportionally to their backlogged queue length,meanwhile made its best effort to flows with the QoS requirement.Flows that have a higher arrival rate were more probable to be chosen,which lead to a fair resource allocation of the total bandwidth.The authors used the link utiliza...
