Abstract
Over-the-air reprogramming is an important aspect in the deployment and management of Wireless Sensor Networks (WSNs). However, WSNs reprogramming poses significant challenges due to scarce available energy, low computational power, and limited memory capabilities of the WSNs nodes; all are required for transmission and processing of the created patches. In existing reprogramming schemes, any change in the program layout and/or global variables, produces a significantly large patch size, hence consumes the node's limited resources. Furthermore, to apply the patch, existing schemes require rewriting internal flash, large volume of external flash, as well as rebooting the node. In this paper, we devise a novel reprogramming scheme that we call Queen's Differential (QDiff), which mitigates the effects of program layout changes and retains the maximum similarity between ”old” and ”new” codes using clone detection techniques. Moreover, QDiff organizes the global variables in a novel way to eliminate the effect of variable shifting. To assess the performance of Qdiff, we have carried out a TinyOS implementation using an IRIS mote platform. Our experiments show that QDiff requires near-zero external flash, and significantly lower internal flash rewriting and transmission overhead than leading existing differential reprogramming mechanisms.

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
