With rapid growth of video traffic over Internet, it becomes a challenging task to provide perceptually good video quality. Enhancement can be done towards improving the Quality of Experience (QoE) by focusing on all relevant layers and across the networks end-to-end. In this paper, the impact of adapting sender bit rate on QoE is analyzed. Furthermore, a mathematical relationship between QoE and bit rate is established which can be extended to include other parameters. Simulation results demonstrate that the quality of non-adaptive video over a bottleneck link is deteriorating to a degree which it becomes annoying, while the same setup produces acceptable QoE when the sender adapts its rate. Moreover, the delay is maintained at an acceptable level as well.
