N2 - In this letter, we propose a QoE-aware video adaptation and resource allocation approach for power-efficient streaming over downlink OFDMA systems. Our adaptation scheme selectively drops packets from a video stream to produce a lower bit-rate version under QoE and delay constraints. This results in a reduction of the load and an increase of the video capacity of the wireless network. Our resource allocation target is to minimize the transmit power by considering the delay requirements of each stream identified in the video adaptation phase. Experimental results have shown significant performance enhancement of the proposed system in terms of end-to-end delay and power efficiency while satisfying QoE requirements.
