Analysis of Distributed Reservation Protocol for UWB-Based WPANs with ECMA-368 MAC
Bibliographic record
Abstract
The recent ECMA-368 standard specifies the use of ultra wideband (UWB) technology for high rate communications in wireless personal area networks (WPANs). This paper proposes an analytical model for the performance analysis of the medium access control (MAC) protocol standardized in ECMA-368. The MAC protocol uses a superframe structure. Each superframe has a beacon period, a distributed reservation protocol (DRP) period, and a prioritized contention access (PCA) period. By using the Markovian arrival process (MAP) and phase type distribution (PH), we model this MAC layer as a MAP/PH/1 queueing system, and focus our study on the performance of the DRP period in this paper. The probability mass function of the number of DRP packets in the system, as well the cumulative distribution of the DRP packet's waiting time are derived and compared with the simulation results in OPNET.

How this classification was reachedexpand
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.
