TCP-friendly streaming in next generation wireless networks

The paper presents an investigation on video streaming over a wireless link. The main goal of this work is to investigate how feedback, rate control and stream adaptation can be used to improve the quality of the streamed video. We focus on the recently standardized TCP-friendly rate control (TFRC) protocol as a mechanism for feedback and rate control. Dynamic switching between video streams is used for stream adaptation. Based on simulations, we investigate the challenging scenario of handovers in wireless networks. The results of these simulations show that our approach increases the quality of video stream delivered to a mobile client in a wireless network.
