| Abstract: | 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. |
