A novel scheduling scheme for finite buffer service in time-varying channels

In this paper, a new scheduling scheme is proposed for finite buffer services in time-varying wireless channel environments. With the proportional fair (PF) principle, we propose the use of a time factor (TF) to guarantee the stability of the system as well as shortening the average user delay. The proposed PF-TF algorithm is parametrically adjustable that can be applied under different channel conditions. Simulation results suggest that the proposed scheme is able to achieve a shorter delay than conventional algorithms.
