Abstract

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 data 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.

Wireless communication has been progressing enormously for the last two decades and has become an indispensable part of our everyday lives
With the rising inclination towards smart devices aiming to support rigorous and advanced data applications, some significant challenges are anticipated in wireless communications due to environmental impact and high energy utilization constraints [1]
The results show that increase in the number of relays, decreases the Outage Probability (OP)

Summary

INTRODUCTION

Wireless communication has been progressing enormously for the last two decades and has become an indispensable part of our everyday lives. N. Ashraf et al.: SWIPT With CoR for Next-Generation Wireless Networks recognizable devices capable of communicating wirelessly with each other on a massive scale via the Internet [1]–[3]. Simultaneous Wireless Information and Power Transmission (SWIPT) is a combined scheme that can transfer power and carry information at the same time It gently grows and provides conciliation between the two basic approaches and uses the RF spectrum adequately to initiate communication and energize the system. SWIPT technology basically provides an efficient spectral solution for energy harvesting, thereby supplying energy and exchanging information with various ultra-low-power devices supporting heterogeneous applications [13].
