Abstract

fetched live from OpenAlex

The medium access control frame duration is limited in wireless local area networks. Severalmodels have been applied to get better utilization of this frame. The frame is composed of different phases and adjusting the use of one phasemay effect the other phases' durations. WiMAX and IEEE802.11 standards have similar physical layer. Channel error due to noise or fading is another problem encounters the safe data delivery to the receiver. Therefore, several schemes have been implemented to deliver safe data to the receiver. In this paper, we propose some analytical models to reduce the contention on the random access phase by developing different backoff strategies. We also develope an error control model for safe data delivery. This is a cross-layer model where we apply our backoff strategies and error control model. The performance matrices for these models are measured by the throughput, acceptance probability, access delay, energy, average number of retransmissions and efficiency.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
