The performance anomaly experienced by nodes in multi-rate wireless local
area networks (WLANs) leads to low throughput and unfairness. To this end,
we propose a distributed, token-based approach that allows applications to
control nodes channel occupancy time via a single tuning knob; {\it token
rate}. Our approach makes use of local information extensively and does
not require any modifications to the IEEE 802.11 MAC nor require explicit
signaling. Simulation results show our approach to be effective in ensuring
fairness and isolating high and low rate flows.
