A high-performance and fair scheduler for the wireless network with a multi-state channel

This work presents a novel scheduler, exponential-rule fair queueing (EFQ), for fair scheduling in wireless networks with a multi-state channel. EFQ prefers flows destined to high-capacity channels to maintain a high throughput, and prefers flows with serious lagging to ensure excellent fairness. Simulation results demonstrate that EFQ not only provides higher throughput, but also maintains superior fairness, than existing schemes.
