Multicasting over Fisher Snedecor F Fading Channel: A Physical Layer Security Analysis

Device to Device (D2D) communication is going to be a promising wireless technology for 5G communication and beyond. So the security aspect of the D2D communication system has been the center of research for quite some time. Since Fisher Snedecor ${\mathcal{F}}$ fading channel is widely used to characterize the D2D communication scenarios, in this work, the data transmission security has been analyzed over Fisher Snedecor ${\mathcal{F}}$ fading channel while simultaneous transmission of same data to multiple receiving devices is considered with the appearance of multiple eavesdroppers. Secrecy performance is measured by deriving different closed-form analytical expressions. i.e. secure outage probability for multicasting, ergodic secrecy multicast capacity, and probability of non-zero secrecy multicast capacity. The adverse effect of both fading and shadowing has been mathematically characterized and solutions to these two problems are graphically represented. Finally, Monte-Carlo simulations are also done to prove the accuracy of the derived mathematical expressions of the proposed model.
