Throughput performance of a busy-tone protocol in CCA modified, long range IEEE 802.11 networks
Bibliographic record
Abstract
Media access protocols define network performance in WLAN/WMAN systems. Such wireless networks are generally short range and use the CSMA (Carrier Sense Multiple Access) protocol which forms the basis to the ubiquitous IEEE 802.11 standard. In this paper we examine the behavior of a hybrid CSMA protocol called the ¿busy-tone protocol¿ which uses a dedicated physical channel to indicate media availability to a highly distributed, wide ranging (3-48 km) hidden set of mobile users. Using the busy tone to gate the radios, we force the radio link into a time domain duplex-like operation with the downlink channel consisting of scheduled concatenated bursts, effectively bypassing the CSMA, while the uplink channel still employs CSMA-like operation. The focus of the simulations is to understand performance of the proposed approach in long range, low S/N scenarios, and consider a hybrid IEEE 802.11 solution that would have improved performance compared to traditional applications of the standard.

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.
