Dynamic Admission and Congestion Control for Real-time Traffic in IEEE 802.11e Wireless LANs |
Abstract | ||
|---|---|---|
The emerging IEEE 802.11e standard for Wireless Local Area Networks (WLANs) has been proposed to support quality of service (QoS) by assigning different channel access parameters (CAPS) to different access categories (ACs). As an important part of QoS, an admission control scheme is required to maximally utilize the wireless medium resources and to efficiently admit the upcoming real time traffic while not compromising the QoS of existing traffic. In this paper, we propose a novel admission and congestion control scheme which obtains the admission control parameters through existing analytical model and traffic QoS requirements. It then dynamically updates the CAPS based on periodical monitoring of current channel conditions. Through numerical analysis and extensive simulation, results show that such a scheme could provide the guaranteed QoS for admitted real-time traffic in terms of guaranteed throughput achievement, bounded maximum delay and bounded maximum dropping rate while maintaining good channel utilization. |
