Abstract
We have developed a theoretical cross-layer model that allows assessing the goodput and delay of
IEEE 802.11 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 fading channels. A
comparison between numerical and simulation results is carried out assuming the IEEE 802.11a
PHY layer.
