Abstract
This paper introduces a new centralized hybrid scheme for high speed wireless local area networks (WLANs), which combines the Out-of-Band Signaling (OBS), the Enhanced Distributed Coordination Function (EDCF) in IEEE 802.11 and the Deficit Round Robin (DRR) technologies to achieve better system performance for high-speed WLANs. We show via simulation that our overall system performance is higher than that of the EDCF in IEEE 802.11, and a certain quality of service and fairness are achieved. © 2004 IEEE.
