  • A number of Notebook PCs, mobilephones, and PDAs are currently integrated with IEEE802.11 Wireless local area network (WLAN) modules orcards for mobile Internet access or other data service. Anew QoS (Quality of services)-oriented hybrid admissioncontrol (QHAC) scheme in IEEE 802.11 WLAN is proposed, with which the performance degradation of WLANincurred by the mobile station at slow transmission rateis overcome by limiting its packet size. In addition, endto-end performance metrics are measured and applied tomake a decision to admission control of new request. Performance analysis and simulation results show that QHACalgorithm can effciently improve the total throughput andfairness index.
