Abstract
The deployment of wireless local area networks (WLANs) in corporate environments along with the increasing demand for quality of service (QoS) support create a need for controlled sharing of wireless link. To satisfy the QoS demand, an on-going standardization work of IEEE 802.11e defines modifications to IEEE 802.11 MAC (medium access control). However, existing MAC scheduling for IEEE 802.11 WLAN focuses majorly on static QoS differentiation. It does not allow the network operator to proportionally adjust QoS classes independent of network load. In this paper we propose a MAC scheduling mechanism that enables dynamic and proportional differentiation of QoS classes in terms of delay. Simulation results show that the proposed mechanism improves proportional delay differentiation in spite of network load variation.
