Analysis of the 802.11 CSMA/CA mechanism has
received considerable attention recently. Bianchi  presents an
analytic model under a saturated traffic assumption. Bianchi’s
model is accurate, but typical network conditions are nonsaturated
heterogenous. We present an extension of his model
to a non-saturated environment. The model’s predictions, validated
against simulation, accurately capture many interesting
features of non-saturated operation. For example, the model
predicts that peak throughput occurs prior to saturation. Our
model also allows stations to have different traffic arrival
rates, enabling us to address the question of fairness between
