Abstract	This paper addresses the problem of congestion control and queue management in multimedia wireless LANs with Quality-of-Service guarantees. The proposed model provides differentiated QOS for different multimedia traffic, which is still an open challenge. This mechanism reduces packet loss rate in wireless networks by Forward Error Correction (FEC) redundancy rate calculation at the access point which reduces the time required for FEC rate calculation at the sender. The number of redundant packets is adaptively adjusted by considering both network traffic load and wireless channel condition. Thus the possibility of congestion due to excessive number of redundant packets is eliminated. Multimedia applications such as Learning-On-Demand and video-conferencing need the special attention for the flow and require differentiated QoS. Thus the proposed work prioritizes the incoming traffic to give p reference to higher priority packets using push-out policy which achieves considerable improvement in the video quality at the receiver. The qualitative analysis is presented which shows that this work is more efficient by introducing push-out scheme to improve the performance further by supporting higher priority multimedia flows.
