A survey: Render of PUE attack in cognitive radio compressed by software defined radio
Mandakini Gupta, Abhishek Jain, Ankur Soni · 2016
PU Emulsion attack is one of the most important Threats of Spectrum sensing for wireless Cognitive Radio Network. On the basis of the Wireless Signal a PU is detected in a given band, all secondary Users should avoid accessing that band. However, when a Secondary user is detected other Secondary users may choose to share that same band. In a Primary user Attack, a malicious Secondary tries to gain priority over other Secondary users by transmitting signals that emulate the characteristic of Primary user's. In this paper we have to adversary to modify the Radio Software of a Cognitive Radio is to change its emission characteristics (i.e. Modulation, Frequency, Power, etc.) so that the emission characteristics resemble those of a PU.
