In Wireless Sensor Networks (WSNs) jamming attacks have become a great concern recently. Finding the location of a jamming device is important so as to take security actions against the jammer and restore the network communication. In this paper, the authors take a comprehensive study on the jammer localization problem, and designed a framework which localizes one or multiple jammers with high accuracy. Current jammer-localization approaches mostly rely on parameters derived from the affected network topology (e.g. packet delivery ratio and hearing ranges).
