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.
