This paper explores the potential of Cooperative Non-Orthogonal Multiple Access (CNOMA) to address the connectivity of cell-edge users in wireless cellular networks by leveraging intra-cell users as relays. These relays retransmit data to cell-edge users, thereby enhancing signal strength through selection diversity. The statistical analysis of connectivity is a critical aspect of understanding the Quality of Service (QoS) and overall performance in CNOMA-based networks. However, analyzing the connectivity of cell-edge users within such networks introduces specific challenges. These challenges include the effects of channel fading and the impact of successive interference cancellation (SIC) in relay users. To address these challenges, this paper provides a closed-form expression for the connectivity of a cell-edge user in a CNOMA-based cellular network, assuming Rayleigh fading channels and the probability of successive interference cancellation (SIC) in relay users. The provided closed-form expression for the connectivity probability of the cell-edge user is then evaluated through simulation results, offering insights to extend its effectiveness.

“…Therein, two iterative approaches were provided for minimization of the outage probability (OP) and maximization of the total ergodic capacity (EC) of NOMA users using a deep neural network technique under real-time environments. The authors of [8] emphasized on the performance analysis of a multiuser (MU) multiple-input single-output (MISO) NOMA IoT framework with simultaneous wireless information and power transfer (SWIPT) protocol. They proposed unique user selection approaches for the energy harvesting (EH) relay, resulting in enhanced system performance in terms of OP.…”

Non-orthogonal multiple access (NOMA) has emerged as an effective technology , aiding in latency reduction, improving security and reliability, and enhancing the spectral efficiency and capacity in Internet of Things (IoT)-enabled communication systems. In this work, an implementation of co-operative secure multiple-input single-output NOMA IoT framework is proposed and examined in a two-fold manner. First, under the consideration of standalone links, a user selection criteria which relies on the characterization of sum ergodic capacity (SEC) is investigated in the presence of an eavesdropper (ED) and beamforming constraints. Next, using the optimized beamformers, a user selection criteria which relies on the outage probability analysis is performed under cooperative relaying considerations. We demonstrate that our optimization approach achieves reduced capacity and coverage for the ED while maximizing the overall SEC and coverage of the network under multiple network configurations. The proposed optimization solution demonstrates superior performance compared to the benchmarked schemes. Derived closed-form analytical expressions are validated through simulation means.

In recent years, there has been a continuous increase in the requirement for consistent connectivity, high-speed data rates, and high quality of service (QoS) for mobile communication. Recent researches show that unmanned aerial vehicle (UAV)-assisted communication improves communication capabilities in terms of reliability, security, cost-effectiveness, and coverage. Also, Non-Orthogonal Multiple Access (NOMA) has the potential to greatly improve the fairness, efficiency, and capacity of wireless networks. In this research paper, we propose a UAV-assisted cooperative NOMA system over Rician fading channels with decode and forward relaying, in which we consider a one-user system and successive interference cancellation is performed by relay. We derive the outage probability, coverage probability, throughput, and ergodic capacity of the proposed system model, compare the performance of the proposed system model with the conventional systems in terms of said parameters, and demonstrate that the UAV-assisted cooperative NOMA-based system has higher performance than the conventional orthogonal multiple access based system. We validate the outcomes of the analytical approach using Monte Carlo simulation.
