Comparative Performance Evaluation of MAC Layer Protocols for Underwater Wireless Sensor Networks
Bibliographic record
Abstract
Underwater Acoustic Wireless Sensor Networks (UAWSN) use acoustic communication for transmitting data. High bit error rate, long propagation delay and limited bandwidth in underwater harsh environment are big issues for designing wireless sensor networks for many applications including ocean monitoring. Another consideration in UWASN is energy constraint. Similar to other wireless sensor networks the design process of energy and efficient bandwidth and also propagation-delay-aware MAC protocols are great challenges in UWASN. In this paper, the performance of three underwater MAC protocols for underwater environment, R-MAC, Slotted FAMA and UWAN-MAC are evaluated. Throughput, energy consumption and packet drop rate are those parameters which are considered for evaluating their performances. These protocols are implemented in Aqua-Sim, an NS-2 based simulator for underwater sensor networks. The simulation results show the effectiveness of the proposed method.

How this classification was reachedexpand
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.
