| 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: | During the process of wireless video transmission based on IEEE802.16d protocol,how to improve the Quality of Service(QoS) architecture was investigated to meet the needs of real-time data transmission that overcomes the shortage of existing QoS architecture.Improvements were proposed by designing a new QoS scheduling algorithm on the basis of existing QoS architecture.According to the characteristics of four categories of service flow,which are supported by IEEE802.16d,the appropriate scheduling algorithm for each category of service flow was selected to ensure correct data transmission.Simulation results of Unsolicited Grant Service(UGS) and Real-Time Polling Service(RTPS) service flows verify the advantages of the new designed QoS architecture. |
