Minimizing Delay in Queuing-based UAV-aided Federated Learning with Straggling IoT Devices
Bibliographic record
Abstract
The Internet of Things (IoT) generates large volumes of data that need secure, reliable, and timely processing to enable effective decision-making. However, the limited processing capabilities of IoT devices often create a bottleneck. To address this, we propose a queuing-based uncrewed aerial vehicle (UAV)-aided edge federated learning (FL) (QUAFL) framework. The proposed framework uses UAVs as mobile edge computing (MEC) servers to process portions of data from the queues of straggling IoT devices that are unable to meet processing deadlines, thereby reducing system delay. We formulate an optimization problem that minimizes system delay by considering UAV-MEC computation power, IoT device computation and communication power, and the capacities of various queues (incoming, offloading, and local processing at IoT devices; incoming and local at UAV-MEC), along with quality-of-service and delay constraints. The problem is reformulated as a Lyapunov-based formulation and then decomposed into three subproblems, which are solved iteratively using closed-form solutions and the sequential quadratic programming (SQP) algorithm. Simulation results demonstrate the impact of various system components on overall delay.

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.
