【摘要】：在基于IEEE802.16d协议的无线视频传输中,为了满足数据实时性的需求,针对服务质量(QoS)框架做的不足提出了补充和改进,并在已有框架的基础上设计出了新的QoS调度框架。在新设计的调度框架中,根据IEEE802.16d协议支持的4种服务流的特性,为每种服务流选择合适的调度算法来保证数据被正确传输。最后通过对主动授予业务(UGS)、实时轮询业务(RPTS)服务流在不同框架下的仿真分析,验证了新框架的优点。
[Abstract]:In the wireless video transmission based on IEEE802.16d protocol, in order to meet the real-time requirement of data, this paper proposes a supplement and improvement to the deficiency of (QoS) framework, and designs a new QoS scheduling framework based on the existing framework. In the newly designed scheduling framework, according to the characteristics of four kinds of service flows supported by IEEE802.16d protocol, a suitable scheduling algorithm is selected for each service flow to ensure that the data is transmitted correctly. Finally, the advantages of the new framework are verified by the simulation analysis of the active grant service (UGS), real-time polling service flow under different frameworks.
