Abstract
A method of mobile video streaming according to an exemplary embodiment of the present invention includes three parts. The first part is for AP to measure the information of all clients such as ETX (Expected Transmission count metric) and RSSI (Receive Signal Strength Indicator) periodically for long-term channel quality and mobility patterns of each client. In the second part, AP estimates the buffer status, short-term channel quality, and mobility detection of each client based on only feedback from the target client and first part result. And lastly, AP performs a practical online scheduling to select the best network code set satisfying high Peak Signal-to-Noise Ratio (PSNR), a standard metric of video quality, during a GoP (Group of Picture) at all clients based on I-frame priority.
