Abstract

A stream-based mapping mechanism (SBM) is proposed for improving the quality of MPEG-4 video delivery. The proposed design keeps two factors in our previous works: significance of video frames and network traffic loads. In addition, SBM considers the action taken on the packet of the same video frame transmitted previously to improve the quality of video transmission over IEEE 802.11e networks. The proposed scheme is evaluated in networks with different traffic loads. The simulation results show that, in terms of frame loss ratio and PSNR (Peak to Signal Noise Ratio), the proposed scheme outperforms exiting schemes such as EDCA (Enhanced Distributed Channel Access), static mapping and adaptive mapping.
