IEEE802.16(WiMAX)主要是由IEEE所制訂的無線通訊標準,主要是應用於WMAN的無線網路規範。在WiMAX環境中,多媒體網路應用為了提供更好的服務品質(QoS),一直是無線網路領域當中很重要的考慮因素。隨著多媒體與無線通訊的發展,主要都需要達到高速資料傳送及低延遲的無線頻寬存取(BWA)服務。而為了實現於多媒體傳輸下更有彈性的視訊串流,由ISO/IEC MPEG和ITU-T VCEG形成的JVT發展出H.264/SVC影像編碼技術,主要是由一個基本層(Base-layer)及多個增強層(Enhancement-layer)所組成的,並具有時間、空間及SNR可調適三大特性,使視訊傳輸品質更能適應於有限的無線網路頻寬資源,達到更好的效能服務。
因此,本論文提出一個跨層設計於強健可調適視訊編碼技術,為了提供更好的QoS,主要探討基於在WiMAX網路傳輸時,透過Hierarchical B-picture將分層架構分成不同等級,並根據不同重要性進行優先權分類,透過佇列使用率來判斷丟棄封包之依據,提供穩定的無線頻寬及最佳傳輸效能,並達到高吞吐量低延遲等服務品質。結合實體層(PHY)和媒介存取控制層(MAC)之特色,並透過網路層(NET)和應用層(APP)提出最佳化之跨層級架構,使得可支援傳輸H.264/SVC,提高在無線網路環境中之視訊傳輸品質。
本論文透過NS2模擬工具在WiMAX網路環境下傳輸H.264/SVC情況,並分析不同服務流之服務品質參數,如封包遺失率、吞吐量、平均延遲率、抖動率。
In WiMAX, the application of multimedia and communication had gathered a great importance in recent years. In considering to provide a better quality-of-service(QoS)issue, the purpose of this study is present about high data transmission and low delay of broadband wireless access(BWA) technology based on IEEE 802.16 Standard. For achieving more flexibility video streams in multimedia transmission, the Joint Video Team(JVT) has already developed the scalable extension of the H.264/AVC standard, as well as which is combined with temporal, spatial and quality scalabilities to adapt the efficient wireless bandwidth resource.
In this thesis, a cross-layer architecture for robust H.264/SVC video delivery over WiMAX network is proposed to obtain a better QoS performance and through the hierarchical B-picture approach to classify video packet into different priority. According to the video priority, the proposed method is used along with utilization rates of queues to determine the drop video packets, to provide more stable wireless bandwidth and improve the video stream quality and transmission of video stream.
Finally, it is shown by NS2 simulations that the proposed method can yield a better performance for packet loss rate, image quality, packet throughput and transmission delay WiMAX network.
