“…Results showed that optimal values of power splitting ratio and time switching factor which minimized BER depends upon number of relay antennas. Authors in [126] considered a multi-relays multi-antenna system with MRC at the destination to choose best combination of signals from relays and antennas for a given SNR. OP and throughput for both TSR/PSR and AF relaying is discussed.…”

Wireless Power Transfer (WPT) is an innovative technology employed for enhancing the energy sustainability of wireless devices with a limited life span. The idea of integrating WPT in wireless communication leads to the idea of Simultaneous Wireless Information and Power Transfer (SWIPT) that transfers information and power to wireless devices simultaneously, thereby resulting in a drastic increase in spectral efficiency of the network. SWIPT aided Cooperative Relaying (CoR) has emerged as a new trend for Fifth Generation (5G) and Beyond 5G (B5G) systems owing to the rapidly increasing challenges faced by these networks. Cooperative relaying combined with SWIPT can be helpful in overcoming the rising demands of next generation wireless networks by providing an enhanced date rate, low latency, shorter coverage, wide spread connectivity of massive number of devices along with energy-efficiency. This article provides a comprehensive review of SWIPT technology that enables the use of CoR networks for 5G and B5G mobile networks including the significance, technologies, and protocols which can be applied. This article also examines the deployment of cooperative SWIPT involving a single relay, multiple relays and optimal relay selection, multi antenna systems and optimal beamforming .SWIPT under the influence of Hardware Impairments (HI), imperfect Channel State Information (CSI), non-linear energy harvesting models, Intelligent Reconfigurable Surface (IRS), massive MIMO, massive access for the Internet of Things (IoT) has been discussed in detail. Meanwhile, this study discusses key challenges being faced in the implementation of SWIPT for future wireless networks that need to be addressed efficiently.

“…When a line of sight link is not presented between transmitter and receiver of PU and SU, cooperative or relaybased communication can be used to obtain more efficient throughput. Cooperative communication is used to improve the system reliability with different relaying techniques such as amplify-and-forward (AF) and decode-and-forward (DF) [5][6][7][8]. Quality parameters are enhanced using multiple-relay cooperative approach especially in different fading channels [9][10][11][12].…”

The spectrum scarcity in communication systems has attracted many researches in the area of cognitive communication which is known as a precious solution to overcome this problem. Overlay (OL) and underlay (UL) strategies are two main techniques in the cognitive systems (CSs). On the other side, cooperative communication improves the reliability and capacity of data communications when using the multiple-relay scheme. In this paper, assuming the multiple-relay cooperative cognitive communication system, the quality of service (QoS) parameters as effective capacity (EC) and outage probability (OP) are analyzed in details. A closed-form mathematical expression is obtained for OP and EC in Rayleigh fading channel considering different constraints on the CS such as false detection of busy/idle state of primary user (PU), or interference threshold of secondary user on PU in OL and UL strategies, respectively. Moreover, the comparison of OL and UL strategies in terms of the QoS parameters is done. As will be shown in this paper, simulation and numerical results verify each other and follow the mathematical analysis of the QoS parameters.

Cooperative communication is used to improve the system reliability with different relaying techniques such as amplify‐and‐forward (AF) and decode‐and‐forward (DF) . The transmission performance characterized by the quality of service parameters can be improved by using proper multiple‐relay cooperative techniques, especially when different fading environments are taken into consideration .…”

The radio spectrum of communication systems is largely occupied by wideband technologies, and thus, efficient usage of spectrum is a crucial requirement from regulators' and service providers' perspectives. Cognitive communication has been proposed as a potential solution to resolve the spectrum scarcity problem.Cognitive radio schemes can be jointly applied with cooperative communications to improve the performance under both overlay and underlay strategies as the two main cognitive strategies supported by multiple relays. This combination significantly improves the reliability and capacity of data communication. In this paper, two QoS parameters, namely, the effective capacity and outage probability, have been thoroughly analyzed in a Nakagami-m fading channel that is the typical channel condition often considered in the transmission of communication systems. Closed-form expressions are obtained for effective capacity and outage probability in both underlay and overlay strategies. Simulation results verify the effectiveness of the mathematical modelling of the proposed QoS parameters.Trans Emerging Tel Tech. 2020;31:e3841.wileyonlinelibrary.com/journal/ett
