An Integrated PHY and MAC Layer Model for Half-Duplex IEEE 802.11 Networks



David W. Griffith, Michael R. Souryal, Camillo A. Gentile, Nada T. Golmie


This paper introduces an IEEE 802.11 analytical model that examines uplink and downlink communications between non-saturated stations and a non-saturated access point. The model integrates channel effects and collisions into a single expression for the probability of frame loss, and does not treat PHY and MAC layer events as independent. In addition, the model considers the half-duplex nature of the IEEE 802.11 channel in determining when transmission attempts succeed.
