Abstract	The paper proposes an error control scheme that dynamically adjusts the polling schedule so that more corrupted messages can be manipulated within their deadlines for real-time communication on IEEE 802.11 wireless LAN. Monitoring the current traffic in the CFP (collision free period) interval as well as inspecting whether a node is executing an error control procedure, the AP (access point) terminates CFP, if possible, to extend the duration of the next CP (collision period). With the enlarged time, the AP gives more polls to the node in need to increase the number of timely recovered messages. Simulation result performed via SMPL shows that this adaptation scheme can reduce the message discard due to transmission error by 5.5%, compared with the existing error controls method for real-time communication on WLAN.
