Abstract

This paper describes a mechanism to adapt an existing wireline scheduling algorithm for a WLAN Access Point, by taking into account the error ratio affecting each flow. This enhancement is based on the idea of weighting flows according to their error ratio. Users connected over error-prone channels get their bandwidth share increased, up to a point where the overall efficiency breaks down, and the mechanism is reverted. The cost of this mechanism in terms of fairness is also addressed.
