Coordinated orthogonal frequency division multiple access (C-OFDMA) and centralized Wi-Fi access network (C-WAN) are two promising techniques for next generation Wi-Fi networks. While C-WAN enables centralized multi-access point coordination and C-OFDMA improves spectrum reuse through resource unit (RU) sharing, fairne...

Due to largely static protocol configurations, IEEE 802.11 (Wi-Fi) channel access offers limited adaptability to dynamic network conditions, particularly in dense and overlapping deployments, leading to inefficient spectrum utilization, increased contention, and packet collisions. This paper investigates reinforcement...

This work compares three collision-free algorithms, CSMA/ECA (ECA), CSMA/E2CA (E2CA), and deterministic backoff (DetBO), with standard and single-stage BEB, and evaluates full-buffer traffic, non-full-buffer ON/OFF traffic with both uplink and downlink transmissions, and coexistence with legacy BEB stations.

A Proportional Fairness (PF)-driven framework for allocating Co-SR transmit power on a per-Transmission Opportunity (TXOP) basis is introduced, and it is proved that any Pareto-optimal power pair keeps at least one AP at its maximum power.
