Performance evaluation of RSSI-based transmitter identification using USRP

Primary User Emulation (PUE) attack is one of the most common attack in the physical layer of the Cognitive Radio Networks (CRN). In order to defense PUE attack, we propose a transmitter identified method based on RSSI of vary frequency to indentify transmitters located in different positions. We use Universal Software Radio Peripheral (USRP) as the transmitter and receiver to verify our method in an indoor environment. Experiment results show that our method can identify transmitters with different locations reliably.
