A MAC and PHY Cross-Layer Analytical Model for the Goodput and Delay of IEEE 802.11a Networks Operating Under Basic Access and RTS/CTS DCF Schemes
Roger Pierre Fabris Hoefel · 2006
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.
