Fig. 6From: Positioning and power optimisation for UAV-assisted networks in the presence of eavesdroppers: a multi-armed bandit approacha Normalised WSC mean values obtained over time, and b cumulative energy consumed in kilo-Joules by all the UAVs over time. Both measured over PLBs with varying uncertainty of the distance between A and B \(\sigma _{\mathrm {AB}}\), compared to the exhaustive search resultsBack to article page
