| 摘 要： | 本文简单介绍了IEEE802.15.3协议,分析了协议的MAC层QoS机制。针对实时VBR(VariableBitRate)业务流,提出了一种改进协议机制的信道资源分配算法,并在性能上与平均资源分配算法进行了分析和比较,通过仿真验证了此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性能。

| Abstract: | The protocol of IEEE802.15.3 are simply introduced in this treatise. The medium access control (MAC) protocol and its QoS are analyzed ,we focus on a new channel time allocation algorithm by modificating the mechanism of the protocol for real-time variable bit rate traffic. Compared with the average channel time allocation algorithm,the performance of the new channel time allocation algorithm is studied . And the result of the simulation shows that the algorithm can efficiently decrease the value of the dropped packets in the transmission of VBR flows. It verifies that it can improve the QoS of the system. |
