Relay Selection for Improved Physical Layer Security in Cognitive Relay Networks Using Artificial Noise

In this paper, the physical layer security of underlay cognitive decode-and-forward (DF) relay networks is investigated, wherein one secondary transmitter (ST) exchanges confidential information with one secondary destination with the assistance of multiple cognitive DF relays by sharing the license...
