IEEE 802.11ah (also known as WiFi Halow) is a new WiFi standard for sub-l GHz communications intended to address key challenges of the Internet of Things. IEEE 802 working group introduces IEEE 802.11ah to overcome the disadvantages of various previously introduced protocols (more data rate and very less transmission range, and more transmission range and very less data rate) by providing much data rate and transmission range of up to 1 km and has the capacity of 8192 devices connecting simultaneously with only one access point. The IEEE 802.11ah standard was released to support Machine-to-Machine (M2M) Communication between a large number of sensor devices that are rapidly increasing with the Internet of Things (IoT). IEEE 802.11ah protocol introduces the RAW Mechanisms in the MAC layer to avoid channel contention, especially when there is a large number of stations trying to access the channel simultaneously, thereby increasing scalability in dense deployments. In this paper, we analyze the network performance in terms of throughput through the proper allocation of nodes. This article investigates the impact of the number of stations and the number of groups on network performance, specifically throughput, in wireless networks. The article examines how varying the number of stations and groups affects the network’s performance and identifies the optimal values for these parameters that can maximize the network’s throughput.
