Physical Layer Security in Cognitive Cooperative Radio Network with Energy Harvesting DF Relay Assisted with Cooperative Jamming

摘要

This paper presents the security in physical layer of cognitive cooperative radio network (CCRN). This network (i.e., CCRN) consists of a cognitive source (CS), a cognitive decode and forward relay (CDFR) with energy harvesting and a cognitive destination (CD). The CCRN uses the bandwidth of a primary network (PN) which contains a primary transmitter (PT) and a primary receiver (PR). The CS does not have a direct link with CD due to deep fading. An eavesdropper is present in the network which tries to decode the message of cognitive network. In this scenario, we have numerically investigated the secrecy performance by a metric named as conditional secrecy outage probability while meeting an outage constraint of PN. MATLAB based is carried out following our analytical development.
