摘　　要：介绍了IEEE802.15.3MAC协议及其QoS机制,分析了超帧中的CAP,针对实时VBR业务流,提出了一种动态资源分配算法,在性能上与平均资源分配算法进行了比较和分析,通过仿真验证了此动态资源分配算法能有效降低实时VBR码流的丢帧率,提高系统传输的QoS。The medium access control (MAC) protocol of IEEE 802.15.3 and its QoS are analyzed in this treatise. The CAP of the superframe is simply considered for the following algorithm. We focus on a dynamic channel time allocation algorithm for real-time variable bit rate traffic. Compared with the average channel time allocation algorithm, the performance of the dynamic channel time allocation algorithm is studied. And the result of the simulation shows that the algorithm can efficiently decrease the rate of the dropped packets in the transmission of VBR flows. It verifies that it can improve the QoS of the system.
