“…Further, they modify ZF and MMSE schemes and develop a scheme which shows better interference cancellation than ZF and MMSE in a NOMA network. Further, in [53] an interference cancellation method namely, multiple interference cancellation (MIC) is introduced for a network with D2D pairs. MIC has a higher performance than the successive interference cancellation utilized in the conventional NOMA scheme.…”

Energy efficiency is a major concern in the emerging mobile cellular wireless networks since massive connectivity is to be expected with high energy requirements from the network operators. Non-orthogonal multiple access (NOMA) being the frontier multiple access scheme for 5G, there exists numerous research attempts on enhancing the energy efficiency of NOMA enabled wireless networks while maintaining its outstanding performance metrics such as high throughput, data rates and capacity maximized optimally.The concept of green NOMA is introduced in a generalized manner to identify the energy efficient NOMA schemes. These schemes will result in an optimal scenario in which the energy generated for communication is managed sustainably. Hence, the effect on the environment, economy, living beings, etc is minimized. The recent research developments are classified for a better understanding of areas which are lacking attention and needs further improvement. Also, the performance comparison of energy efficient, NOMA schemes against conventional NOMA is presented. Finally, challenges and emerging research trends, for energy efficient NOMA are discussed.

A large number of mobile multimedia terminals are prominent features of smart cities. Device-to-device (D2D) communication takes advantage of the limited bandwidth resources of cellular networks to accommodate more mobile devices. However, when D2D pairs reuse cellular users channels, serious interference leads to energy consumption, which dissatisfies the requirements of green communication. This paper focuses on energy efficiency maximization of D2D communication under the constraints of both D2D pairs and cellular users quality of service. The formulated resource allocation problem is NP-hard, which is usually difficult to solve within polynomial time. To make the problem easy to handle, we divide it into power control and channel allocation sub-problems. In particular, we propose a power control algorithm based on the Lambert W function to maximize the energy efficiency of a single D2D pair. The preference values of D2D pairs and cellular users are calculated using the power control results, respectively. A channel allocation scheme based on the Gale-Shapley algorithm utilizes preference values to match two sides, which aims at maximizing the signal to interference plus noise ratio of cellular users and the energy efficiency of D2D pairs. The simulation results show that the proposed algorithm could not only guarantee the transmission rate of cellular users but also improve the system and D2D pairs energy efficiency.INDEX TERMS Device-to-device (D2D) communication, cellular networks, energy efficiency, resource allocation, green communications.

A nonorthogonal multiple access (NOMA) enabled downlink single‐cell communication network with cooperating relay nodes, is considered in this article. NOMA simultaneously transmits signals to a group of users. The formation of the group users, in NOMA, depends on their spatial restrictions. These spatial restrictions are defined by the transmission range of the relay equipment. Therefore, it is important to find the transmission range of the relay. This article presents a novel angle selection scheme for finding the transmission range of the relay. Ever‐increasing cellular traffic needs improvement in data rates and power saving. So, an adaptive NOMA scheme in which the system adaptively chooses its working model is proposed in this article. The adaptive NOMA scheme maximizes the sum rate and optimizes the energy efficiency of the fifth‐generation communication network. It also reduces the power consumption at the circuit of the end‐user equipment, hence, achieving power saving. Comprehensive numerical results emphasize that the proposed scheme achieves higher system energy efficient as compared to the conventional NOMA scheme. Such an adaptive framework also improves the average signal‐to‐interference noise ratio and the fairness factor, as shall be examined. The implications of proposing an adaptive NOMA network are evaluated through simulation results.
