“…The developed network based on MIMO was demonstrated to outperform conventional networks whereas the existing methods are not incommensurate with the dynamic deployment and flexible configuration in the multi-robot networks. We also note that the development of 5G technology has demonstrated the advantages of full-duplex communication systems in terms of high communication rate and spectrum utilization [24]. Here, full-duplex wireless nodes have a demonstrated capability for accommodating simultaneous transmission and reception in the same frequency band, therefore they can effectively double the data transmission rate [25].…”

The present work addresses the challenging problem of coordinating power allocation with interference management in multi-robot networks by applying the promising expansion capabilities of multiple-input multiple-output (MIMO) and full duplex systems, which achieves it for maximizing the throughput of networks under the impacts of Doppler frequency shifts and external jamming. The proposed power allocation with interference coordination formulation accounts for three types of the interference, including cross-tier, co-tier, and mixed-tier interference signals with cluster head nodes operating in different full-duplex modes, and their signal-to-noise-ratios are respectively derived under the impacts of Doppler frequency shifts and external jamming. In addition, various optimization algorithms, including two centralized iterative optimization algorithms and three decentralized optimization algorithms, are applied for solving the complex and non-convex combinatorial optimization problem associated with the power allocation and interference coordination. Simulation results demonstrate that the overall network throughput increases gradually to some degree with increasing numbers of MIMO antennas. In addition, increasing the number of clusters to a certain extent increases the overall network throughput, although internal interference becomes a severe problem for further increases in the number of clusters. Accordingly, applications of multi-robot networks require that a balance should be preserved between robot deployment density and communication capacity.

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.

“…In other words, there can exists uplink and downlink transmissions simultaneously between one STA and one AP. In [ 19 ], a full duplex MAC protocol using frequency domain coordination was proposed for the next-generation WLAN. In the protocol, the AP specifies STAs to report channel information on the specified subchannel, and schedules full duplex link transmission, and STAs must have full duplex capability.…”

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.
