Abstract
In this study, we propose a novel secure heterogeneous network system model that incorporates an unreliable wireless backhaul and perfect channel estimation across identical Rayleigh fading channels. Our approach employs three transmission schemes: Sub-Optimum Selection (SS), Optimum Selection (OS), and Minimum-Eavesdropping Selection (MES), with the goal of improving the secrecy performance of the system. We derive advanced closed-form expressions for the Secrecy Outage Probability (SOP) for these three selection schemes in both practical and ideal scenarios. We investigate the influence of uncertainties in wireless backhaul and perfect Channel State Information (CSI) on the system’s secrecy performance. Furthermore, we examine how the number of small-cell transmitters impacts the system’s secrecy performance. By conducting Monte-Carlo simulations, we validate the accuracy of our analytical results. This verification ensures the correctness of our expressions and strengthens the reliability of our findings.
