Abstract-We have developed a theoretical cross-layermodel that allows assessing the goodput and delay of IEEE802.11 local area networks (WLANs) operatingsimultaneously under the distributed coordination function(DCF) basic access (BA) and request-to-send/clear-to-send(RTS/CTS) medium access control (MAC) protocols undersaturated traffic over correlated fading channels. Acomparison between numerical and simulation results iscarried out assuming the IEEE 802.11a PHY layer.
