“…The interruption probability and delay tolerance capacity are investigated by analyzing two scenarios with successfully paired users and without successful pairing, and the superiority of its scheme is demonstrated by theoretical analysis and simulation.Literature [25] proposes to introduce NOMA in D2D mobile groups under uplinks, thus exploring interference suppression schemes to maximize network throughput. The authors model the problem as a mixed integer linear programming problem by joint user pairing and resource allocation, and prove the superiority of the proposed scheme using a three-dimensional game, branch definition method, and successive convex approximations.Literature [26] proposes a NOMA and D2D communication scheme to improve the physical layer security of D2D users, and at the same time to obtain higher rates by clustering, using matching theory and sub-optimization algorithms to solve the user clustering and power allocation problems, respectively, and finally the significant advantages of the authors' proposed approach are confirmed by simulations.With the introduction of D2D pairs in the NOMA system, the decoding complexity of the system also increases. Literature [27] addresses the large decoding complexity by mentioning the use of the Lagrangian pairwise method and the cyclic triangular successive elimination scheme to reduce the computational complexity of decoding.…”

Device-to-device(D2D) communication combined with non-orthogonal multiple access(NOMA) can further improve the quality of service for future communications systems and increase spectrum utilization and connection density in cellular networks. In this paper, an effective power allocation scheme is designed to optimize the performance of a D2D communication system based on NOMA for imperfect Successive Interference Cancellation(SIC) decoding. To solve the non-convexity of the problem due to integer constraints and coupling variables, an alternate optimization algorithm was designed to obtain the optimal solution of each subproblem by Lagrange duality analysis and the sub-gradient descent method. Finally, the numerical simulation results demonstrate the performance advantages of the proposed joint optimization algorithm for channel resource allocation and power control in energy efficiency.INDEX TERMS Non-orthogonal multiple accesses, D2D Channel resource allocation, Power allocation, Lagrange duality analysis.

SummaryIn the rapidly evolving landscape of fifth generation Internet of Things (5G‐IoT) networks, Device‐to‐Device (D2D) communication has emerged as a promising paradigm to enhance secrecy transmission rate (STR) and connectivity. However, the security of D2D communications in the presence of eavesdroppers remains a critical challenge. This article investigates the problem of optimizing D2D transmit power to achieve secure D2D communication while considering the presence of random eavesdroppers in 5G‐IoT networks. We propose a novel secrecy‐based power control approach (SRMWPCA) approach to model the random distribution of eavesdroppers in the network, taking into account their varying distances from D2D pairs and deliberately increasing interference at the eavesdropper's link. By leveraging tools from stochastic geometry, we derive an analytical expression for the secrecy transmission probability (STP), which quantifies the probability of eavesdroppers successfully decoding the D2D transmission. In this analysis, we have incorporated practical considerations such as channel fading, path loss, and interference from other devices. To enhance the security of D2D communication, we formulate an optimization problem to determine the optimal transmit power levels for D2D pairs, subject to constraints on the secrecy transmission probability and interference to the cellular network. We propose an efficient algorithm to find the power allocation that maximizes the secrecy outage performance while meeting these constraints. Simulation results demonstrate the effectiveness of the proposed approach in achieving secure D2D communication in 5G‐IoT networks with random eavesdroppers. The performance of the proposed SRMWPCA approach improved by 23.25% and 20.9% compared with standard approaches in terms of the secrecy rate and throughput of the users from malicious attacks.

“…With the objective of maximizing the network throughput by investigating a joint resource allocation problem of user clustering, power control, and D2D mode selection, the authors in [17] considered a NOMA-D2D system where D2D users can reuse the resources in cellular networks or share the unlicensed band with WiFi users. In [18], the authors investigated the advantage of employing NOMA in D2D communications, where D2D pairs are clustered with content demanders. Each D2D transmitter communicates with its corresponding receiver, while simultaneously, communicates with a demander via NOMA technique.…”

In the context of future ultra-dense mobile networks, spectrum and energy efficiencies (SE and EE) are critical measures in designing efficient systems for the sixth-generation (6G) of wireless networks. Recognized for their benefits in increasing SE and EE, non-orthogonal multiple access (NOMA) and device-to-device (D2D) communications are combined in this work to present a new NOMA-based D2D scheme increasing the performance in terms of SE and EE. The users in the proposed scheme are split into coalitions. Coalition heads are served in NOMA directly from the base stations, while the other users within the coalitions get the service through D2D links. We investigate the system’s SE and EE for different mobility patterns, and we discuss optimal system configurations with the help of Monte Carlo simulations. The obtained results show that the proposed system exhibits a better performance compared to conventional OMA and NOMA models, especially in low mobility contexts.
