JLPR: Joint range-based localization using trilateration and packet routing in Wireless Sensor Networks with mobile sinks
Bibliographic record
Abstract
Location-awareness plays an important role in Wireless Sensor Networks (WSNs) by aiding in tasks such as packet routing, event mapping, and energy savings. The use of Global Positioning System (GPS) on sensor nodes is not always viable due to a number of issues, e.g., power constraints. Location estimation solves the problem of computing sensor node positions by using information from devices that can house a GPS module, e.g., a mobile sink. However, GPS error may affect the accuracy of position estimations. In this paper, we propose a range-based scheme that uses trilateration and also handles GPS error. The proposed approach takes advantage of sink beacons used in packet routing. These beacons are used as position packets in order to estimate the position of nodes while reducing network overhead. However, a mobile sink poses issues when used as a source of position packets. Therefore, we propose Position Distance, Circle Limit and a Hybrid version of the algorithms in order to decide on the best position packets from the sink to be used in trilateration. An extensive set of performance evaluation experiments is conducted and results show that the proposed algorithms can improve position estimation accuracy, while sustaining acceptable packet delivery ratio and reducing network overhead.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
