| 摘 要： | 对无线网络接入点上下行TCP流存在的时间不公平性现象进行了研究,报告了无线网络接入有线网络存在的拥塞控制问题现状,提出了一种的无线网络TCP流公平调度算法。采用快速的TCP流优先发送方法,既保证了各流吞吐率公平性,又解决了慢速的TCP占用信道时间过多的问题,实现了各流占用信道的时间公平性。通过网络仿真实验证明,新的公平调度算法比传统的算法在性能上有较大的改进,达到了提高网络整体效率的目的。

| Abstract: | The time unfair phenomenon of up/downlink TCP(transmission control protocal) flow in wireless network access point was studied and the problem of congestion control in wireless network access was reported. A fairness scheduling algorithm for TCP flows was proposed in wireless network. The algorithm adopts the method of fast TCP flow transmission priority, which not only ensures the throughput fairness of TCP flow, but also solves the problem that slow TCP flow occupies too much channel time. And thus the time fairness of occupying channel of TCP flow was realized. Network simulation experiments show that the new fair scheduling algorithm has better performance than the traditional algorithm and it improves overall efficiency of network. |
