On Throughput Estimation with TXOP Sharing in IEEE 802.11ah Networks

Nowadays the concept of the Internet of Things (IoT) becomes more and more popular. However, state-of-the-art wireless technologies do not meet the IoT requirements for low power consumption and big number of simultaneously connected devices. To meet IoT requirements, IEEE 802.11 Working Group is developing a new low-power long-range Wi-Fi, called HaLow, which is described in the new IEEE 802.11ah amendment to the Wi-Fi standard. To increase the network coverage and decrease power consumption of sensors, the new amendment introduces relaying. A part of this mechanism is TXOP sharing, which hastens two-hop frame exchange. In this paper, we develop the first analytical model of relaying with TXOP sharing in IEEE 802.11ah networks, which allows estimating network throughput.
