Cognitive Radio Ad Hoc Networks (CRAHNs) are prone to Primary User Emulation Attacks (PUEAs), a particular security issue in which malicious unlicensed users manipulate their cognitive radio parameter values to monopolize the spectrum usage pretending transmissions of Primary Users. Works in the literature propose to detect or mitigate these attacks, however they are based on network architectural...
In Cognitive Radio Ad Hoc Networks (CRAHNs), malicious Secondary Users can exploit CR (Cognitive Radio) capabilities to perform Primary User Emulation Attacks (PUEA). These attacks pretend the transmission of a Primary User (PU), giving to malicious users the priority of using licensed frequencies over well-behaved unlicensed Secondary Users (SU). Since CRAHNs are envisioned as a solution for the...
