In this paper, we propose a non-orthogonal multiple access (NOMA) based grouping method for IEEE 802.11ah, promising platform the internet of things (IoT). The improves scalability IoT networks, by reducing collisions in points (APs). proposed puts those devices (IoT-Ds) whose channel gains are far enough from each other, i.e., who satisfy NOMA constraints, same group. Therefore, using successi...
