We have developed a theoretical cross-layer model that allows assessing the goodput and delay of the IEEE 802.11a local area networks (WLANs) operating simultaneously under the distributed coordination function (DCF) basic access (BA) and request-to-send/clear-to-send (RTS/CTS) medium access control (MAC) protocols under saturated traffic over correlated and uncorrelated fading channels.
