Abstract
For the video packets delivery over 802.11e WLAN networks, an improved cross-layer mapping (ICLM) scheme is presented in this paper. There are four access categories (ACs) in the 802.11e MAC layer. The ICLM scheme maps the video packets to the ACs according to both the significance of the video packets and the current network conditions. The simulation results show that this scheme can effectively enhance the end-to-end video quality over WLAN networks.
