| 摘 要： | 提出了一种适用于采用无线接入多媒体流的拥塞控制算法,简称adaptive-MQWB(adaptivemediaQoSandwirelessbandwidth)。该算法依据当前带宽的动态变化率,在满足多媒体传输的最大时延的前提下,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。仿真结果表明,与目前已有的MADR、tuned-RED算法相比,adaptive-MQWB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。

| Abstract: | A congestion control scheme, adaptive media QoS and wireless bandwidth (adaptive-MQWB) was presented for multimedia traffic from the Internet. Satisfying the maximum delay of multimedia transfer, the adaptive-MQWB al-gorithm seeks an optimal active queue management scheme for the optimal target queue according to the dynamic vary-ing rate of current bandwidth. The simulation results show that the varying-time of adaptive wireless bandwidth and the QoS guaranteed in multimedia transfers delay with the adaptive-MQWB algorithm are superior to those of MADR algo-rithm and tuned-RED algorithm. |
