Abstract

Mitigating the impact of errors on video quality over wireless network has been a major issue of concern which requires highly efficient and effective scheme. The dynamic and heterogeneous nature of the wireless network requires highly sophisticated approach to mitigate the impact of transmission error on video quality. The trade-off between delay and video quality should be considered while designing such applications to reasonably maintain video quality in wireless channel. In order to significantly reduce the impact of high error bit and error burst on transmitted video, more efficient error correction scheme are needed. In this paper, we paper presents an approach using forward error correction and cross layer mechanism which dynamically adapts with the channel condition to recover the loss packets in order to enhance the perceived video quality. The scenario has been simulated using NS-2 and it shows more dramatic improvement in video quality.
