“…On the other hand, alternative wireless information and power transfer strategies are significant for the sustainable growth of wireless communications, especially with enormous energy consumption growth with ever-increasing connected devices [5,7]. In order to show the performance gain of EH-CNOMA over CNOMA without EH, the EC and OP of simultaneous wireless information and power transfer (SWIPT) aided CNOMA (SWIPT-CNOMA) have been evaluated [34][35][36][37]. The EH (TS and PS) for FD/HD CNOMA has been evaluated in terms of the OP and compared with conventional OMA [38].…”

Cooperative non-orthogonal multiple access (CNOMA) has recently been adapted with energy harvesting (EH) to increase energy efficiency and extend the lifetime of energy-constrained wireless networks. This paper proposes a hybrid EH protocol-assisted CNOMA, which is a combination of the two main existing EH protocols (power splitting (PS) and time switching (TS)). The end-to-end bit error rate (BER) expressions of users in the proposed scheme are obtained over Nakagami-m fading channels. The proposed hybrid EH (HEH) protocol is compared with the benchmark schemes (i.e., existing EH protocols and no EH). Based on the extensive simulations, we reveal that the analytical results match perfectly with simulations which proves the correctness of the derivations. Numerical results also show that the HEH-CNOMA outperforms the benchmarks significantly. In addition, we discuss the optimum value of EH factors to minimize the error probability in HEH-CNOMA and show that an optimum value can be obtained according to channel parameters.

“…The OPAFs are obtained by solving the convex optimization (CO) nonlinear optimization problem. In Nayak and Gurrala, 25 the authors developed the mathematical framework for deriving the OPAFs in a simultaneous wireless information and power transfer (SWIPT) C-NOMA cooperative communication network with combined power splitting (PS) and time switching (TS) algorithms. In Nayak and Gurrala, 25 the authors have considered frequency flat Rayleigh fading channel conditions and the RN, which is the NU employing the AF relaying protocol.…”

“…In So and Wong, 27 the authors investigated the PS-based SWIPT NOMA network and proposed a dual-layer approach to solving the non-CO optimization framework considering the EH network. Even though a wide range of NOMA methods have been provided in the literature, 20–27 the suggested techniques’ key assessment scenario is communications with poor bandwidth efficiency in fading channels with large-scale fading and short root mean square delay spread (40,300 nanoseconds), since they are aimed at commercial platforms. Since the BS, NU, and FU are all traveling in a military situation, the channel is always not stagnant and changes, so the channel situations and usage cases can be very different from commercial ones.…”

In a defense scenario, the communicating nodes are mobile and, due to this, the fading channel links become time selective in nature. Non-orthogonal multiple access (NOMA) is a promising technique in modern wireless communication systems, and it is employed in a variety of defense ad hoc wireless communication scenarios where nodes are mobile and it is difficult to estimate the channel coefficients perfectly. NOMA contributes to increased spectral efficiency (SE), firstly by enabling fifth-generation new radio deployment in the 3.5 GHz frequency range, and secondly by employing a simultaneous wireless information and power transfer (SWIPT) time switching and power splitting-based cooperative NOMA (C-NOMA) network where simple radio frequency circuitry is used for energy harvesting. NOMA together with the selective decode-and-forward (S-DF) protocol will increase the SE and energy efficiency simultaneously. The outage probability performance is evaluated for various values of the fading severity parameter and node velocity forming the channel error. It is significant to note that digital S-DF-based SWIPT C-NOMA performs much better than an analog amplify-and-forward-based C-NOMA SWIPT system.
