Abstract
This paper proposes a comprehensive but tractable model of IEEE 802.11 carrying traffic from a mixture of saturated and unsaturated (Poisson) sources, with potentially different quality-of-service (QoS) parameters, i.e., TXOP limit, CW min, and CW max. The model is used to investigate the interaction between these two types of sources, which is particularly useful for systems seeking to achieve load-independent fair service differentiation. We show that, when the TXOP limit for unsaturated sources is greater than one packet, batches are distributed as a geometric random variable clipped to TXOP limit. Furthermore, we present asymptotic results for access delay distribution, which indicates t..
