Three Dimensional UAV Positioning for Dynamic UAV-to-Car Communications [PDF]

open access: yesSensors, 2020
In areas with limited infrastructure, Unmanned Aerial Vehicles (UAVs) can come in handy as relays for car-to-car communications. Since UAVs are able to fully explore a three-dimensional environment while flying, communications that involve them can be affected by the irregularity of the terrains, that in turn can cause path loss by acting as obstacles.
