Defense against Primary User Emulation Attacks in Cognitive Radio Networks
We propose a transmitter verification scheme, called LocDef (localization-based defense), which verifies whether a given signal is that of an incumbent transmitter by estimating its location and observing its signal characteristics. Expand
