Enhancing IEEE 802.11 Standard with Deep Reinforcement Learning for Optimal Channel Access
Bibliographic record
Abstract
According to IEEE 802.11 standard, the collision avoidance mechanism is not the most efficient as it relies on a binary exponential backoff (BEB) algorithm. This algorithm increases the backoff interval whenever a collision is detected, aiming to reduce the likelihood of future collisions. The influence of this algorithm causes bandwidth wastage and decreases network performance dramatically in dense networks. Moreover, an incorrect backoff setting leads to more collision occurrences, making channel access very challenging. This work proposes using reinforcement learning (RL) algorithms, namely Deep Q Learning (DQN) and Deep Deterministic Policy Gradient (DDPG), to solve such an optimization problem. The proposed approach uses the average transmission queue level as an observation metric, with throughput as the reward and contention window value as the action. Simulation results based on NS3-gym show that DQN and DDPG outperform BEB for a dynamically increasing number of stations (dynamic scenario), showing a 45.52% increase in throughput with 50 stations.

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.
