Secrecy analysis of the cloud-Fog radio access network with poisson point process and general path-loss parameters

Abstract

Cloud-fog radio access is a promising technology in evolving wireless communication systems, but its success depends on security. It is fundamental to conduct the secrecy analysis in the physical layer due to the special architecture of CF-RAN. In this paper, we investigate the secrecy impacted by general path-loss effects. We show that the mathematical kernel is the Weibull distribution function with non-integer parameters. This type of problems was challenging since it is not covered in popular mathematical handbooks. However, with the aid of a recently discovered result in the literature, we are able to solve this issue and derive the solution in the closed-form. The presented results provide the necessary facility to expedite the secrecy analysis for other variants of CF-RAN. The simulation shows that the impact of path-loss fading on secrecy is more significant than that of deployed device intensity.
