Abstract

This paper analyzes and evaluates joint effect of primary interference and artificial noise on information securing capability of cognitive radio networks (CRNs) under interference power constraint, peak transmit power constraint, and Rayleigh fading. An exact formula for an important security performance metric, secrecy outage probability, is first derived and then validated by computer simulations. Finally, this exact formula is used to provide numerous results to show security performance saturation at large peak transmit power or large peak interference power, adverse effect of primary interference on security performance, and security performance improvement owing to artificial noise.
