Abstract
The hybrid carrier-sense multiple access (CSMA)/time-division multiple access (TDMA) medium access control (MAC) protocol combines the strengths of CSMA and TDMA protocols. In this letter, we propose a dynamic queue-length-based time slot allocation scheme for the hybrid CSMA/TDMA MAC protocol to improve channel utilization considering the uncertainty in queue length information. Due to the lack of a dedicated control channel from a device to the coordinator, the queue length in a device can be reported to the coordinator only in an intermittent manner. To overcome this difficulty, the proposed scheme calculates the probability mass function (pmf) of the distribution of the queue length and allocates slots during the TDMA period based on this pmf. The simulation results show that the proposed slot allocation scheme outperforms the time slot allocation scheme which does not take into account the distribution of the queue length.

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 it
