“…In recent years, the combination of NOMA and SWIPT technologies in cooperative networks has received a considerable amount of attention. For example, in [ 12 , 13 , 14 ], different types of NOMA–SWIPT cooperative relay network models are proposed, and the resource allocation optimization methods is studied with the goal of outage performance of the networks. On this basis, other studies also comprehensively consider the impact of the throughput [ 15 , 16 , 17 , 18 , 19 ], diversity gain [ 20 , 21 , 22 ], and user transmission distance [ 23 , 24 ], verifying that the cooperative relay network of NOMA–SWIPT fusion has a good prospect in energy and resource optimization.…”

In order to improve the energy efficiency (EE) performance of cooperative networks, this study combines non-orthogonal multiple access (NOMA) with simultaneous wireless information and power transfer (SWIPT) technologies to construct a cooperative relay network composed of one base station (BS), multiple near users, and one far user. Based on the network characteristics, a time-division resource allocation rule is proposed, and EE formulas regarding direct-link mode and cooperative mode are derived. Considering user selection and decoding performance, to obtain the optimal EE, this study utilizes a DinkelBach iterative algorithm based on the golden section (GS-DinkelBach) to solve the EE optimization problem, which is affected by power transmitted from the BS, achievable rates under three communication links, and quality of service (QoS) constraints of users. The simulation results show that the GS-DinkelBach algorithm can obtain precise EE gains with low computational complexity. Compared with the traditional NOMA–SWIPT direct-link network model and the relay network model, the optimal EE of the established network model could be increased by 0.54 dB and 1.66 dB, respectively.

“…Different NOMA schemes are investigated with cooperative relaying that can enhance the reliability of NOMA users, who has weak channel conditions. 5,6 Liu et al 7 examined a NOMA system with cooperative relaying in which the strong user helps the weak user in information transmission. Next, in previous studies, 8,9 a NOMA system is investigated with basic relaying schemes and derived the expression for the outage.…”

In this work, a new control jamming (CJ) scheme has been proposed for a cooperative nonorthogonal multiple access (NOMA) network with optimal power allocation factors by employing decode-and-forward (DF) relay.Maximization of secrecy rate at both NOMA users with the aid of CJ under total transmit power constraint is considered as an optimization problem. In this regard, invasive weed optimization (IWO) algorithm-based approach is proposed to facilitate optimal power allocation for the considered network. In this analysis, performance metric secrecy rate is analyzed with CJ at both NOMA users by varying the location of eavesdropper with respect to the relay and jammer. In addition, the performance of fixed power allocation (FPA) and proposed power allocation (PPA) schemes is investigated with CJ and compared with jamming (J) and without jamming (WJ) conditions. Simulation result analysis specifies that secrecy performance is enhanced remarkably by CJ and PPA outperforms the FPA.
