Abstract
Abstract Recently, vehicular ad hoc network (VANET) has emerged as a promising approach for road safety and traffic efficiency improvement through a variety of vehicle applications enabled by communications between vehicles such as emergency braking warning, etc. However, due to its unique characteristics, such as intermittent connectivity due to high‐speed mobility of the network nodes (or vehicles), also known as vehicular delay tolerant network, it poses a major challenge to the realization of those applications. In this paper, we propose a new roadside unit (RSU) aided bundle forwarding protocol for vehicular delay tolerant networks. Furthermore, with the assistance from those RSUs deployed at some critical points on the road, for example, intersections, the proposed protocol can increase the network performance in terms of delivery ratio. At the same time, since vehicle‐to‐vehicle (V2V) and vehicle‐to‐RSU (V2R) privacy‐preserving authentications are guaranteed, the black (gray) hole attacks can be avoided. Extensive simulations demonstrate the effectiveness of the proposed protocol. Copyright © 2010 John Wiley & Sons, Ltd.

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
