摘要：
In this paper, a real-time video conferencing framework is proposed for multiple conferencing pairs by joint considering the uplink and downlink conditions within IEEE802.11 networks. We formulate this system as to minimize the maximal end-to-end expected distortion received by all users by selecting the PRY modes and transmission time. Compared with the strategy of individually optimizing uplink and downlink, the proposed framework outperforms by 3.67 similar to 8.65 dB for the average received PSNR among all users.
