Behavior of clock-sampling mutual network synchronization in wireless sensor networks
Bibliographic record
Abstract
Clock synchronization is an important component of wireless sensor networks both for co-ordination of node communications and for time stamping sensor data. The properties of the previously presented clock sampling mutual network synchronization algorithm (CS-MNS) are explored. The desirable properties of this algorithm include simplicity, low communication and processing overhead, and fully decentralized operation. Past simulation and analysis has shown clock convergence under specific conditions in single hop networks. We show that in the absence of offset errors the network clocks converge. In the presence of offset error we present conditions on the degree on clock asynchrony under which the network clock rates show convergent behavior. The analysis is applicable as long as the network topology is connected and thus is of interest in both single-hop and multi-hop environments. We show how the network designer can use these conditions to add a bias term to the CS-MNS algorithm and thus improve the start-up dynamics of the algorithm. Additionally, we discuss the algorithm from a security standpoint. Finally, we propose a method for adding external reference synchronization that is compatible with our security discussion.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
