Enhancing HAP Networks with Reconfigurable Intelligent Surfaces
2024 6th International Conference on Communications, Signal Processing, and their Applications (ICCSPA)This paper presents and analyzes a reconfigurable intelligent surface (RIS)-based high-altitude platform (HAP) network. Stochastic geometry is used to model the arbitrary locations of the HAPs and RISs as a homogenous Poisson point process. Considering that the links between the HAPs, RISs, and users are $κ$--$μ$ faded, the coverage and ergodic ...
