Effect of Nakagami-m Fading on Secrecy Outage of Energy Scavenging Underlay Cognitive Networks

Abstract

The current paper proposes the exact analysis on the secrecy outage probability of energy scavenging cognitive radio networks over Nakagami-m fading channels and under both (interference and maximum transmit) power constraints and primary interference. The suggested analysis is verified by Monte-Carlo simulations. Multiple results demonstrate that primary interference, required security degree, and fading severity drastically impact the security performance. Moreover, this performance can be minimized by cleverly selecting time fraction.
