ABSTRACT
We present Wit, a non-intrusive tool that builds on passive moni-
toring to analyze the detailed MAC-level behavior of operational
wireless networks. Wit uses three processing steps to construct an
enhanced trace of system activity. First, a robust merging proce-
dure combines the necessarily incomplete views from multiple, in-
dependent monitors into a single, more complete trace of wireless
activity. Next, a novel inference engine based on formal language
methods reconstructs packets that were not captured by any moni-
tor and determines whether each packet was received by its destina-
