Effective TCP-friendly transmission for video streaming over AWGN wireless channel

In this paper, video streaming over AWGN wireless channel combined with wired links is investigated based on VFR-TCP model (Variable Frame Rate based on TCP-Friendly Rate Control). The model is proposed to evaluate the predicted frame rate for MPEG-4 video streaming. Quality of Service (QoS) is also accounted for the predicted quantizer scale Q, if the network throughput is assumed to be equal the required bandwidth. Simulation results show that the VFR-TCP model increases tolerance to packet loss due to network congestion as well as channel bit errors and achieves a reasonable quality.
