Performance analysis of ad-hoc wireless LANs for real-time traffic
Bibliographic record
Abstract
Compelling features of wireless local area networks (WLAN) put a variety of wireless service demands in place. In order to adjust system parameters to fulfill the specific needs of different applications, a mathematical description of the system tends to be helpful. The inherent complexity of wireless access makes this description very challenging. We propose a new performance model for the IEEE 802-11 WLAN in ad-hoc mode. The ad-hoc mode has been chosen since we eventually aim at interconnected WLAN clusters where no base station exists. The model is based on the presentation of the system with a pair of one-dimensional state diagrams which can easily accommodate variations of many input parameters. The corresponding state variables are contention window size and buffer occupancy of each user in the system. The input parameters considered are: packet fragmentation factor; buffer size; maximum allowable number of retransmissions. However, the approach taken is capable of ingesting any other probable parameters of interest. System performance criteria under study are: throughput; delay; probability of failure to deliver. The last two are crucial for real-time applications.

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.
