A wireless network congestion control algorithm based on adaptive qos and wireless bandwidth

为了实现对无线网络进行有效的拥塞控制,本文提出了一种自适应性的主动队列管理算法(adaptive Qos andwireless bandwidth,adaptive-QWB).该算法根据当前带宽的动态变化率,在满足传输最大传输时延的前提下,以最佳目标队长为实现目标,寻求最优的主动队列管理方案.实验结果表明,与已有的MADR、tuned-RED算法相比,adaptive-QWB算法在带宽动态变化的自适应性和多媒体传输时延的QoS保证方面都表现出更好的性能优势.

To control wireless network congestion an adaptive Qos and wireless bandwidth（adaptive-QWB） was designed in this paper.The adaptive-QWB algorithm seeks an active queue management for the optimal target queue according to the dynamic varying rate of current bandwidth.The experiment results show that the varying-time of adaptive wireless bandwidth and the QoS guaranteed in transmission delay with the adaptive-QWB algorithm are superior to those of MADR algorithm and tuned-RED algorithm.
