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.
