Abstract

In this article, we derive the Secrecy Outage Probability (SOP) and the Probability of Strictly Positive Secrecy Capacity (SPSC) for Cognitive Radio Networks with Adaptive Transmit Power. Our analysis takes into consideration the interference between primary and secondary nodes. The Secondary Source SS and relays Rk adapt their power to generate low interference at Primary Receiver (PR). We derive the SOP and SPSC at the secondary destination in the presence of an eavesdropper.
