An improved affinity propagation method for maximising system sum rate and minimising interference for 3D multi‐UAV placement in disaster area

IET Networks, Volume 14, Issue 1, January/December 2025.
In emergency situations where ground base stations are disabled, UAVs, due to their low cost and high adaptability, restore communication coverage in remote areas. The main challenge is optimally determining the three‐dimensional positions of the UAVs to meet dynamic user demand and reduce interference.
