Abstract DCF performs unfairly within multi-rate wireless LAN. Higher rate stations occupy channel for less time, and they can only obtain the same throughput as lower rate stations. This paper presents fair-time-share MDCF, which sets different initial contention windows for stations with different rates. Theoretical analysis and simulation results both show that MDCF can greatly improve the time-fairness and throughput of multi-rate wireless LAN.
