Abstract :
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 Physical (PHY) and Medium Access (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.
