Abstract

The IEEE 802.1 le standard allows an admission control (AC) criteria based on medium time calculation for contention-based wireless access. In this standard, medium time is derived from minimum physical layer (PHY) rate and static surplus bandwidth allocation (SBA) parameters. However, a pessimistic minimum PHY rate and fixed SBA would result in channel underutilization. Therefore, we propose an efficient AC algorithm based on adaptive PHY rate and SBA that enhances the user capacity with quality of service (QoS) provision.
