“…As the main carrier of Internet of Things (IoT), wireless local area network (WLAN) is widely used due to its advantages of low cost and easy deployment [ 1 , 2 ] and has become a research hotspot in industry and academia. During the past decade, with the rapid development of mobile Internet, many new applications and requirements have emerged and people’s demand for wireless traffic has increased rapidly at a compound annual growth rate of 47% from 2016 to 2021 [ 3 ], where the requirements for transmission delay and jitter are more stringent.…”

The Wireless Local Area Network (WLAN) has become a dominant piece of technology to carry wireless traffic for Internet of Things (IoT). The next-generation high-density WLAN scenario is very suitable for the development trend of the industrial wireless sensor network. However, in the high-density deployed WLAN scenarios, the access efficiency is low due to severe collisions, and the interference is diffused due to the scattered locations of the parallel access stations (STAs), which results in low area throughput, i.e., low spatial reuse gain. A spatial group-based multi-user full-duplex orthogonal frequency division multiple access (OFDMA) (GFDO) multiple access control (MAC) protocol is proposed. Firstly, the STAs in the network are divided into several spatial groups according to the neighbor channel sensing ability. Secondly, a two-level buffer state report (BSR) information collection mechanism based on P-probability is designed. Initially, intra-group STAs report their BSR information to the group header using low transmission power. After that, group headers report both their BSR information collected from their members and inter-group interference information to the access point (AP). Finally, AP schedules two spatial groups without mutual interference to carry on multi-user full duplex transmission on the subchannels in cascading mode. The closed-form formulas are theoretically derived, including the number of uplink STAs successfully collected by AP, the network throughput and area throughput under saturated traffic. The simulation results show that the theoretical analysis coincide with the simulation results. The system throughput of the GFDO protocol is 16.8% higher than that of EnFD-OMAX protocol.

The succeeding peers high density based WLAN set-up is seemingly appropriate for expansion drift in manufacturing wireless sensor-based networks. A spatial group-based multi-user full-duplex orthogonal frequency division multiple access (OFDMA) (GFDO) multiple access control (MAC) protocol was projected previously for the static topology with enhanced spatial reuse-gain since powercontrol technology decreases the signal coverage which also reduce cluster size, resulting in elimination of the overlapping area, minimize the occurring collisions. According to our research, we approached to build a dynamic topology with varying densities using the adaptive DBSCAN clustering technique that can maintain both power and increase signal range, while eliminating the overlapping areas as the nodes can now be mobile and densities of the network is balanced throughout the topology. The adaptive DBSCAN demonstrates work efficiency for groups with changed densities that can work significantly well for classifying clusters with varying-densities that achieve a successful efficiency rate for dataset where clusters have the constant density of data points, also significant attributes for this algorithm are noise cancelation.
