[Abstract]:In order to improve the quality of video transmission in WLAN 802.11, the 802.11 working group introduces an enhanced distributed channel access protocol, but this protocol does not fully consider the characteristics of video data. Based on the research of the network protocol, an improved cross-layer adaptive mapping strategy is proposed. The quality of video transmission in 802.11 network can be improved by considering the importance of video packet and the current network state in the process of transmission control. The simulation results of this algorithm are compared with those of other algorithms. The comparison results show that the video transmission quality of the algorithm is superior to that of other algorithms in WLAN 802.11.
