In this paper, we study MPEG-4 transmissions over the IEEE 802.11 wireless local area networks (WLANs). First, we provide a simulation of MPEG-4 using OPNET over the WLANs in terms of throughput, impacts of multiple MPEG-4 streams, and compression rate on throughput. Our simulation results show that a higher throughput does not always yield a better quality MPEG-4 video. We further observe that if an I frame of MPEG 4 video is lost, the next N-1 frames (all P and B frames) are useless [where N… CONTINUE READING
