A Joint Link Budget and MAC/PHY Cross-Layer Model for DiffeServ IEEE 802.11e WLANs

An analytical medium access control (MAC) and physical (PHY) cross-layer model to calculate the link budget and to estimate the cell coverage of IEEE 802.11e wireless local area networks (WLANs) is derived. A comparison between numerical and simulation results is carried out assuming the IEEE 802.11a and IEEE 802.11g PHY layers.
