3D Deployment of UAVs for Communications under Multiple Eavesdroppers
Bibliographic record
Abstract
This paper proposes to use UAVs with adjustable beamforming as mobile base stations and studies to deploy them in a 3D manner to ensure secure communications in the presence of eavesdroppers. We aim to deploy the UAVs with appropriate beamforming in the optimal positions to maximize the signal strength of normal users while jamming the eavesdroppers by minimizing their received signal strength. Specifically, the objective is to maximize the total number of successfully served APs and jammed eavesdroppers. To achieve the goals, we propose a genetic algorithm (GA) by adjusting the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{3D}$</tex> positions and beamwidths of UAV s. Simulation results show that the signal-to-interference-noise-ratio (SINR) threshold significantly affects the overall performance, and the proposed GA outperforms the existing differential evolution algorithm (DE).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
