On Physical Layer Security Over the Fisher-Snedecor ${\mathcal{F}}$ Wiretap Fading Channels

In this paper, we initially investigate the physical layer security over device-to-device communications, where the channel is modeled from the Fisher-Snedecor .T distribution. To be specific, secrecy metrics, including the secrecy outage probability, the probability of non-zero secrecy capacity, and the average secrecy capacity, are well derived with exact closed-form expressions, which are given in terms of the Meijer's G-function. The accuracies of our mathematical expressions are further validated by Monte Carlo simulation results.
