Unmanned Aerial Vehicles Meet Reflective Intelligent Surfaces to Improve Coverage and Secrecy. (arXiv:2205.02506v1 [cs.CR])

The high configurability and low cost of Reflective Intelligent Surfaces
(RISs) made them a promising solution for enhancing the capabilities of Beyond
Fifth-Generation (B5G) networks. Recent works proposed to mount RISs on
Unmanned Aerial Vehicles (UAVs), combining the high network configurability
provided by RIS with the mobility brought by UAVs. However, the RIS represents
an additional weight that impacts the battery lifetime of the UAV. Furthermore,
the practicality of the resulting link in terms of communication channel
quality and security …
