Extracting Jamming Signals to Locate Radio Interferers and Jammers

摘要

We study the problem of localizing a constant jammer that continually emits radio signals, regardless of whether the channel is idle or not. Current jammer-localization methods mostly rely on parameters derived from the affected network topology, such as packet delivery ratios (PDR) [3] and nodes' hearing ranges |2|. Using these parameters makes it difficult to accurately localize jammer's position. We seek to localize jammer by using directlv the strength of jamming signals (JSS).
