A Sensor Based Attack Detection and Localization Mechanism in Cognitive Radio Networks
Jianbin Tang · Journal of Xiamen University · 2012
To address the primary user emulation(PUE),sybil,jamming and selfish attacks in cognitive radio networks(CRN),this paper proposes a sensor-based security mechanism to simultaneously detect multiple types of wireless attacks and to locate the attacker for further actions.Utilizes multiple sensors to measure the receive signal strength(RSS),this mechanism can exploit the spatial decorrelation property of radio media to address wireless attacks.In addition,it can effectively deal with the change of the transmit power in CRN.Experimental results based on spectrum analyzer and USRP show that this mechanism can accurately detect spoofing Sybil attack,jamming and selfish attacks,as well as to accurately locate the attackers,with the average localization error as small as about 0.9 m.
