Abstract
One of the goals of developing Wi-Fi 6 and Wi-Fi 7 standards is to support real-time applications (RTAs) that have strict requirements for latency and data delivery reliability, as well as the power consumption of RTA stations that transmit such data. To meet the above-mentioned Quality of Service (QoS) requirements, Wi-Fi 7 proposes the use of the R-TWT mechanism, an improved version of the TWT mechanism widely used in Wi-Fi 6 networks, which is capable of meeting more stringent QoS requirements but is complex to implement and has limited support from real devices. The article develops an analytical model for data delivery using TWT and R-TWT mechanisms, which for the first time allows estimating the probability of RTA station frame delivery within a given time and the throughput of conventional devices in heterogeneous Industrial Internet of Things networks. The developed model is used to find parameters that maximize the throughput for conventional stations while meeting the QoS requirements of RTA stations.
