The massive spread of the smart devices demanding high data rate and delay‐sensitized applications has escalated energy consumption levels in the fifth‐generation (5G) wireless communication networks (WCNs). It thus becomes imperative for the mobile network operators to meet the tremendous subscriber demands using energy‐efficient techniques. The limited battery capacities of the mobile terminals (MTs) further make energy efficiency (EE) critical. Device‐to‐device (D2D) communication ensues to be a key enabler technology in the realization of an energy‐efficient 5G WCN. It also serves as a paramount technology for green communication. This paper studies a resource allocation scheme, which iteratively accentuates adaptive reuse of resource blocks (RBs) from the active cellular users to the D2D pairs in a tri‐sectored cell. The cellular users involved in RB allocation to pairs are termed as active. Required count of RBs for each D2D pair is chosen by employing the hidden Markov model. The RB reuse strategy favors enhancement in throughput. The proposed energy‐efficient adaptive RB allocation with low complexity (E2ARC) scheme aims to guarantee ample RBs to individual D2D pairs to optimize the power consumption levels. With advanced throughput and optimal power, augmentation in EE is achieved with a high degree of fairness. E2ARC also comprehends low complexity. The efficacy of the proposed scheme is demonstrated by the simulation results.

“…For each CU, the D2D reuse partner (D2D‐TX) is the one located at the farthest location. The idea of location‐based pairing of cellular and D2D users has been also used in the work of Dinh‐Van et al Following user pairing, the mode selection, power control, and resource partitioning can be accomplished independently for each set based on the proposed schemes.…”

In this paper, we consider the problem of mode selection, resource allocation, and power control for device‐to‐device (D2D) communications in cellular networks. We propose optimization frameworks based on max‐min fairness and proportional fairness where cellular and D2D links share the cellular resources. The optimization problem is solved in different resource sharing modes (ie, cellular, overlay, and underlay), and the mode leading to the highest optimal value is selected in the system. We further propose a two‐stage mode selection scheme based on channel quality in which the resource partitioning is expressed in closed form. We compare the performance of the proposed schemes with that of optimization framework based on sum‐rate and no‐mode selection scheme. The numerical results indicate that cellular and D2D links achieve higher rates in proportional fairness and max‐min fairness schemes compared to no‐mode selection scheme. While the rate improvement of D2D link is more significant in sum‐rate optimization, the cellular link may achieve lower rate in this scheme compared to other methods including the no‐mode selection scheme. The results also reveal that the rates of cellular and D2D links in channel quality scheme can vary within the range of rates obtained in max‐min and sum‐rate optimization frameworks.

“…Also, under the premise of ensuring the communication quality and transmit power of D2D users in each D2D group, the optimal power allocation scheme is obtained using Karush-Kuhn-Tucker (KKT) conditions. To demonstrate the effectiveness of the proposed algorithm, the performance in terms of energy efficiency and throughput is compared with the current state-of-theart algorithms [2], [17], [21] and the traditional D2D-OMA algorithm under different system parameters and conditions.…”

The performance of the future mobile communication system could greatly improve as a result of Device-to-Device (D2D) communication and Non-Orthogonal Multiple Access (NOMA). Reduction of the interference between the D2D users and cellular users is crucial in improving the overall throughput and efficiency of the D2D communication based on NOMA. This paper proposes a joint sub-channel and power allocation algorithm for D2D communication based on NOMA to maximize the uplink energy efficiency and throughput of the mobile communication system. The algorithm uses the Kuhn-Munkres (KM) technique to allocate a channel for each D2D group and formulates an optimal power allocation problem using Karush-Kuhn-Tucker (KKT) conditions. Simulations indicate that the proposed algorithm outperforms the current state-of-the-art algorithms in regards to energy efficiency and throughput under different network conditions.
