Maximizing the lifetime of wireless sensor networks through domatic partition
Bibliographic record
Abstract
Distributing sensing and data gathering tasks to a dominating set is an attractive choice in wireless sensors networks since it helps prolong network lifetime by engaging such a subset of nodes for these tasks and letting other nodes go into energy-efficient sleep mode. Because they are busy all the time for sensing, processsing, and transmitting data, nodes in the dominating set quickly run out of energy. One possible way to overcome this situation is to find a number of dominating sets among the nodes of the network and use them one by one iteratively. In this paper, we investigate the problem of finding the maximum number of disjoint dominating sets called the domatic partition problem in unit disk graphs. Although the domatic partition problem is NP-hard in general graphs, it is unknown whether the same is true for unit disk graphs. However, we present an algorithm towards solving this problem (approximately) together with experimental results and give a conjecture based on our results about the maximum number of disjoint dominating sets in unit disk graphs.

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.
