摘要
In this paper, we study the secrecy outage probability of an untrusted relaying energy-harvesting system in the presence of an eavesdropper network, which chooses the best eavesdropper to overhear much of the sources confidential signal. To degrade the overhearing capacity and give additional energy at the untrusted relay, the destination sends artificial noise signals during the communication. For secrecy outage evaluation, we derive the analytical expression for the secrecy outage probability (SOP) and a high-power approximation for the SOP. The accuracy of the analytical results is verified by Monte Carlo simulations.
