- Abstract
- In this paper, we investigate an active Reconfig- urable Intelligent Surface (RIS)-assisted unmanned aerial vehicle base station (UAV-BS) system for disaster communication net- works. To mitigate the cascaded path loss in the UAV–RIS–user equipment (UE) link, an active RIS capable of amplifying reflected signals is employed. The coverage performance is eval- uated and compared with three benchmark architectures: UAV- BS-only, passive RIS-assisted, and amplify-and-forward (AF) relay-assisted systems. Simulation results demonstrate that the active RIS significantly improves the coverage probability and effectively restores the coverage of the failed base station in disaster environments.
