Analyzing the Impact of TXOP Allocation on Legacy Devices in IEEE 802.11bd Networks
Bibliographic record
Abstract
This paper presents a comprehensive analysis of V2X communication, focusing on the transition from IEEE 802.11p to IEEE 802.11bd standards, and introduces an analytical framework combining M/G/1 queuing analysis and Markov chain analysis. Our model includes saturation and non-saturation states of Enhanced Distributed Channel Access (EDCA) in the scenarios with and without fallback mechanism for IEEE 802.11bd Next Generation Vehicles (NGV) and focuses on optimizing Transmission Opportunity (TXOP) allocation for legacy (non-NGV) devices whilst taking into account the impact of vehicle-to-roadside Unit (RSU) distance. Our results show increased throughput for higher-priority traffic classes with augmented TXOP allocation for NGV devices and highlight the need to align RSU transmission coverage with On-Board Unit (OBU) data patterns and vehicle distance to prevent network saturation.

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.
