Throughput-Optimal Opportunistic Scheduling in the Presence of Flow-Level Dynamics
Abstract—We consider multiuser scheduling in wireless networks with channel variations and flow-level dynamics. Recently, it has been shown that the MaxWeight algorithm, which i...

Multi-User Buffer Control with Drift Fields
Abstract--Multi-user buffer control is a closed-loop transmission strategy to ensure users buffers do not underflow or overflow. The dynamic scheme requires buffer state informatio...

Energy-Efficient Multi-Carrier Link Adaptation with Sum Rate-Dependent Circuit Power
Abstract--Energy-efficient link adaptation is studied for transmission on a frequency-selective parallel AWGN channel. The total power dissipation model includes a circuit power th...
