Abstract

Wireless LANs have achieved a tremendous amount of growth in recent years. During this time, user requirements have evolved, so it is necessary to have differentiation mechanisms in the access networks to achieve user requirements. WLAN standard IEEE 802.11 doesn't provide any differentiation between different services to achieve throughput and delay requirement, this paper propose a new modification to the IEEE 802.11 MAC distributed coordination function (DCF) to support differentiation between best effort services and delay sensitive services, the analytical model shows that application can tune modified MAC parameters to achieve a given degree of service differentiation.
