Channel-independent throughput-based fair queueing in wireless packet networks

Abstract

We propose a new fair queueing scheme which we call Channel-Independent Throughput-based Fair Queueing (CITFQ) without using virtual time system. In our CITFQ scheme, each flow is equipped with a counter that measures the weighted throughput achievement if it has a backlog of packets. Our CITFQ scheme achieves fairness guarantees, short term fairness for error-free flows, long term fairness for error flows, and graceful degradation for flows which have received extra service.
