Abstract

We propose a powerful new MAC/PHY cross-layer approach to estimating link quality in 802.11WLANs. Unlike previous approaches, we explicitly classify channel impairments into noise-related losses, collision induced losses, hidden-node losses and 802.11 impairments caused by exposed nodes and capture effects. Our approach distinguishes among these different types of impairments without requiring any modification to the 802.11 protocol and provides separate quantitative measures of the severity of each one. Our approach is suited to implementation on commodity hardware and we demonstrate both a prototype implementation and experimental assessments.
