Probabilistic Co-OFDMA: Performance in Overlapping Wi-Fi 6 Networks

This paper presents a design formulation and evaluation of a wireless co-OFDMA probabilistic algorithm aimed at optimizing resource utilization in overlapping Wi-Fi networks. The design formulation is grounded in realistic industrial application requirements, and the evaluation is conducted using the network simulator v3.0 with its DetNetWiFi module, which is capable of modeling deterministic wireless networks. The evaluation focuses on latency, jitter, and packet loss. Our findings demonstrate that co-OFDMA probabilistic approaches offer significant benefits in terms of latency in deterministic wireless environments. However, they may also introduce increased jitter compared to a static primary channel sharing scheme, aspect which may not be suitable to industrial wireless environments.
