Simulation of Mobile Hydroacoustic Communications in Underwater Acoustic Sensor Networks
Bibliographic record
Abstract
We study the software simulation of underwater acoustic communications with mobility in UWASNs. We simulate the mobility of sensors and their communications, moving according to the Meandering Current Mobility (MCM) model. OMNeT++ and MATLAB are used to model and integrate three protocol layers of UWASNs: network, link, and physical. The effects of noise and attenuation on the underwater communications are considered in the physical layer model. Three major metrics are calculated in this work: Bit Error Rate (BER), distance, and signal energy per bit over noise power spectral density (Eb/N0). Finally, the performance of communicating sensors moving according to the MCM model is evaluated. The simulation results illustrate that the BER for digital data signals is an increasing function of the distance. In addition, the BER for digital data signals is a decreasing function of the Eb/N0 ratio.

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.
