【摘要】:在基于IEEE802.16d協(xié)議的無(wú)線視頻傳輸中,為了滿足數(shù)據(jù)實(shí)時(shí)性的需求,針對(duì)服務(wù)質(zhì)量(QoS)框架做的不足提出了補(bǔ)充和改進(jìn),并在已有框架的基礎(chǔ)上設(shè)計(jì)出了新的QoS調(diào)度框架。在新設(shè)計(jì)的調(diào)度框架中,根據(jù)IEEE802.16d協(xié)議支持的4種服務(wù)流的特性,為每種服務(wù)流選擇合適的調(diào)度算法來(lái)保證數(shù)據(jù)被正確傳輸。最后通過對(duì)主動(dòng)授予業(yè)務(wù)(UGS)、實(shí)時(shí)輪詢業(yè)務(wù)(RPTS)服務(wù)流在不同框架下的仿真分析,驗(yàn)證了新框架的優(yōu)點(diǎn)。
[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.
