Security analysis in generalized shotgun cellular systems over generalized composite fading channels

In this paper, we investigate the efficacy of physical layer security (PLS) in Wyner's three -node model, implemented in the n -dimensional (n -D, n =1, 2, and 3) shotgun cellular system (SCS). In this setup, base stations (BSs) are randomly distributed using a non -homogeneous Poisson point process (PPP) across n dimensions on the entire plane and it is assumed that the receiver possesses knowledge of the channel coefficients. Our investigation employs a generalized composite fading channel (GCFC) model, which encompasses both generalized -Gamma (GG) distributed small-scale fading and large-scale fading modeled by the log -normal distribution, for all links between BSs and a mobile station (MS), as well as the link between the eavesdropper and the transmitter within the n -D SCS. The findings presented, substantiated through Monte Carlo simulations, provide valuable insights into the influence of GCFC on the secrecy performance of the n -D SCS.
