Effective Packet Scheduling with Fairness Adaptation in Ultra Wideband Wireless Networks
Bibliographic record
Abstract
Ultra-wideband (UWB) transmission is an emerging wireless technology, and medium access control (MAC) with quality of service (QoS) provisioning is essential to coordinate the access among competing devices in UWB-based wireless networks. In this paper, we study the exclusive region concept (which was previously proposed) to determine the active set of senders at a time. We find out that, different from the previous work, the exclusive region for a specific link should be a system-level concept, and should depend on system factors such as interference from/to other active links. Based on the findings, two MAC packet scheduling schemes are proposed to exploit the system capacity and, at the same time, to achieve a certain level of fairness in UWB wireless networks. As the long acquisition time in UWB transmission can significantly reduce the system efficiency, the proposed schemes can be modified to alleviate the negative effect of a long acquisition time. Computer simulations demonstrate the effectiveness and efficiency of our proposed schemes

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
