This paper proposes and analyzes the performance of an error control scheme for multicast video streaming over IEEE 802.11 WLAN. The proposed scheme makes all packets include the field indicating the number of packets of the message to which they belong, the receiver nodes report errors in a best-effort manner through contention period, and finally access point retransmits the requested packets through the overallocated slot that is unavoidably brought by QoS guarantee. Simulation results show that the proposed scheme can not only efficiently utilize the network bandwidth by reusing the wasted bandwidth for error control but also reduce the deadline miss ratio by 23 % compared with fixed length-based error control scheme without affecting other streams.
