Proportional Fairness in 802.11 Wireless LANs
Alessandro Checco, Douglas J. Leith · IEEE Communications Letters · 2011
We provide the first rigorous analysis of proportional fairness in 802.11 WLANs. This analysis corrects prior approximate studies. We show that there exists a unique proportional fair rate allocation and completely characterise the allocation in terms of a new airtime quantity, the total air-time.
