A Unified Architecture for the Design and Evaluation of Wireless Fair Queueing Algorithms

摘要

Fair queueing in the wireless domain poses significant challenges due to unique issues in the wireless channel such as location- dependent and bursty channel errors. In this paper, we present a wireless fair service model that captures the scheduling requirements of wireless scheduling algorithms, and present a unified wirless fair queueing architecture in which scheduling algorithms can be designed to achieve wireless fair service. We map seven recently proposed wireless fair scheduling algorithms to the unified architecture, and compare their properties through simulation and analysis. We conclude that some of these algorithms achieve the properties of wireless fair service including short-term and long-term fairness, short-term and long-term throughput bounds, and tight delay boudns for channel access.
