| dc.description.abstract | 動機：由於無線感測網路(Wireless Sensor Network, WSN)具有體積小、成本低、容易佈建、可動態組成等優點，近年來已被廣泛應用到各種領域，例如居家照護。然而感測器擁有的能力有限，加上無線網路的高錯誤率，發展視訊串流的應用必須克服諸多挑戰。
作法：本論文提出一個建構在無線感測網路的多來源視訊串流架構。此外，本論文提出的基於優先權R2CP為多對一通訊協定，能夠區分視訊中frames重要性的差異，並且具備來源互補的能力。 成果：本論文採用H.264/AVC編碼器與解碼器證明I-frame的重要性遠大於P-、B-frame，並且進一步分析封包大小與slice損壞數量之關聯；最後本論文採用自行開發的R2CP與P-R2CP模擬器，證明P-R2CP能夠提供較佳的傳輸品質。 | zh_TW |
| dc.description.abstract | Motivation: Because wireless sensor network has advantage of small-size, low-cost, densely-deployed and self-organizing, its applications has covered a lot of domains recently, such as home care. However, its applications to video streaming still need overcome high error-rate of wireless network and limited capabilities of sensors.
Method: This thesis proposes not only the architecture of multi-source video streaming on wireless sensor network, but a multi-source transport protocol named priority-based R2CP, which is capable of distinguishing the critical frames and complementing the lack of multi-source. Achievement: This thesis adopts H.264/AVC encoder and decoder to prove that I-frame is most critical ones. Besides, we further analyze the relationship between packet size and the volume of damaged slice. This thesis finally adopts the R2CP and P-R2CP simulator to prove that P-R2CP is able to provide better transmission quality. | en |
