The content delves into the analysis of secrecy outage probability (SOP) in opportunistic user scheduling schemes for secure RIS-aided wireless communications. It compares suboptimal and optimal scheduling approaches, providing insights into system parameters affecting secrecy performance.
The study evaluates the SOP behavior at high signal-to-noise ratio (SNR), demonstrating saturation levels with varying numbers of RIS elements and users. It also compares opportunistic user scheduling with non-orthogonal multiple access (NOMA) based schemes.
Furthermore, the content discusses the performance comparison between relay-aided systems and RIS-aided systems, highlighting critical factors influencing deployment decisions. The analysis emphasizes the importance of realistic path loss models in evaluating SOP accurately.
Overall, the study provides a comprehensive examination of SOP in different user scheduling scenarios within RIS-aided wireless communication systems.
