Abstract
Cellular networks have witnessed increasing demands for higher data rates in the recent years. Satisfying these demands presents a challenge for cellular network operators. Video traffic plays a major role in this, as it accounted for more than half of the data traffic on cellular networks recently. Device-to-Device (D2D) communication, introduced by the Long Term Evolution-Advanced (LTE-A) standard, allows direct communication between User Equipments (UE) in the network. We proposed cached and segmented video download algorithms that employ D2D communication to improve the throughput of video transmission over LTE-A cellular networks. Here, we present the Modeling and Simulation (M&S) of an LTE-A network that implements the proposed algorithms. We used the Discrete Event System Specification (DEVS) formalism to model the network. Simulation results show that significant improvements are achieved by the proposed algorithms in terms of the average and aggregate data rates.

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 it
