Energy-Efficient Path Construction for Data Gathering Using Mobile Data Collectors in Wireless Sensor Networks
Bibliographic record
Abstract
Energy is seen as a significant factor in wireless sensor networks (WSNs).It is a challenge to balance between battery lifetime of the different sensors and network lifetime.The main contribution of the proposed approach is to decrease the energy consumption of each sensor node, overcome unbalanced energy usage among sensor nodes, reduce the data gathering time and enhance the network lifetime.To achieve these goals, we combine the Hierarchical Agglomerative algorithm and an optimal path selection method.First, the suitable cluster heads (CHs) are elected based on the Euclidean distance and the residual energy of each sensor node.Then, the base station is situated at the center of the field, which will be partitioned into equal subareas, one for every mobile data collector (MDC).Second, the Kruskal algorithm is used to create an optimal data gathering path from each subset of elected cluster heads.Finally, each mobile data collector travels the optimal path to collect the data from the set of cluster heads of each subarea and returns periodically to the base station to upload gathered data.Computer simulation proves that the proposed approach outperforms existing ones in terms of data gathering time, residual energy and network lifetime.

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.
