Secure Wireless Communication Through Composite Rayleigh-Gamma Fading Channels

This paper examines the secure performance of a composite Rayleigh-gamma fading channel when an eavesdropper is present in the channel. The aim of this work is to investigate the effect of gamma shadowing incorporating Rayleigh fading for the analysis of security in wireless communication networks in terms of probability of non-zero secrecy capacity (PNZSC) and secure outage probability (SOP). The analysis demonstrates that the shadowing effect substantially improves the security of the proposed model. Furthermore, Monte-Carlo simulations are carried out to confirm the accuracy of the theoretical findings.
