Abstract

We evaluate two approaches for estimating the proportions of frame losses at an 802.11 station due to collisions and interference. These methods use only local 802.11 measurements available in basic access mode. We implement the estimators on an experimental testbed using off-the-shelf hardware to investigate implementation requirements and to evaluate performance in real wireless environments. We find that the estimators are accurate and of potential practical utility.
