| 摘 要： | 在保证可分级视频流延时要求的情况下，为了有效提高其在无线网络中传输的带宽利用率，提出了一种新的调度方案。该方案利用可分级视频流的分解特性以及不同的流采用不同的调度周期来提高带宽利用率。数值结果表明该方案非常有效，特别是当物理层传输速率较大的时候，其有效性更加明显。

| Abstract: | To improve the bandwidth utilization of scalable video streaming transmission while guaranteeing the delay requirement in IEEE 802.11e wireless networks, a novel scheduling scheme is proposed. The improvement of bandwidth utilization lies in that the decomposable feature of scalable video streaming and the different scheduling periods for different streams are jointly considered. Numerical results show that the proposed scheme is very effective, particularly prominent when the physical transmission rate is large. |
