Proportional Fair Scheduling with Capacity Estimation for Wireless Multihop Networks

In this paper, we investigate the scheduling problem to achieve the proportional fairness among the flows in wireless multihop networks with time-varying channel capacity. Using the signal to interference noise ratio and the outage probability, we present an estimate of time-varying capacity. Then, we achieve the proportional fairness in terms of maximizing the network utility functionwith consideration of fast fadingwithoutmeasurement of channel state information. Finally, we show that the proposed scheme results in better performance compared to the existing schemes through the simulation results.
