A Survey on Simultaneous Wireless Information and Power Transfer With Cooperative Relay and Future Challenges

Abstract

The integration of simultaneous wireless information and power transfer (SWIPT) and cooperative relay (CoR) techniques has evolved as a new phenomenon for the next-generation wireless communication system. CoR is used to get energy and spectral efficient network and to solve the issues of fading, path loss, shadowing, and smaller coverage area. Relay nodes are battery-constrained or battery-less devices. They need some charging systems externally as replacing or recharging of their batteries sometimes which are not feasible and convenient. Energy harvesting (EH) is the most cost-effective, suitable, and safer solutions to power up these relays. Among various types of the EH, SWIPT is the most prominent technique as it provides spectral efficiency by delivering energy and information to the relays at the same time. This paper reviews the combination of CoR and SWIPT. From basic to advanced architectures, applications and taxonomies of CoR and SWIPT are presented, various forms of resource allocation and relay selection algorithms are covered. The usage of CoR and SWIPT in the fifth-generation wireless networks is discussed. This paper focuses on the integral aspects of the CoR and SWIPT to other next-generation wireless communication systems and techniques such as multiple-input-multiple-output, wireless sensor network, cognitive radio, vehicular ad hoc network, non-orthogonal multiple access, beamforming technique, and the Internet of Things. Some open issues and future directions and challenges are given in this paper.

On-Site and External Energy Harvesting in Underground Wireless

“…It is important because information and energy are interrelated as underground WDs are required to harvest enough energy by WPT before transmitting the information. To that end, a WPT-related technology to wirelessly energize a sensor node known as Simultaneous Wireless Information and Power Transfer (SWIPT) [24,54] is also reviewed. Unlike traditional WPT, SWIPT simultaneously transfers information and power in the same signal instead of transferring power only.…”

“…Wireless Power Transfer (WPT): WPT converts wireless Radio Frequency (RF) signals into electrical energy to power up the buried nodes [24]. Numerous wireless methods, e.g., electromagnetic induction, electromagnetic resonance, or radiation, can be used to transfer energy [25][26][27][28].…”

Energy-Neutral Operation Based on Simultaneous Wireless Information and Power Transfer for Wireless Powered Sensor Networks

“…SWIPT has been applied to WSNs in various ways to overcome their energy limitations. Numerous surveys of SWIPT in WSNs have been published recently [29][30][31]. For instance, [29] summarized the current research on SWIPT-based cooperative sensor networks, in which SWIPT is applied to WSNs in terms of dual-hop and multi-hop relays.…”

Meanwhile, [30] focused on the integral aspects of SWIPT in other prominent networks, such as device-to-device networks, vehicular ad hoc networks, wireless body area networks, WSNs, and so on, and presented open issues and challenges in SWIPT application. In [31], an overview of SWIPT/WPT-enabled WSNs was provided and future directions were suggested.…”

Sum‐throughput maximization for overlay cognitive wireless powered network with energy harvesting capability

“…The SWIPT technique also allows users to simultaneously perform wireless information transmission (WIT) and WPT 13 . Some studies have been used SWIPT techniques in a variety of structures such as point‐to‐point channels, 14,15 relay‐based systems, 16,17 multiuser orthogonal frequency division multiple (OFDM) systems, 18‐20 multiple‐input multiple‐output (MIMO) channels, 21,22 opportunistic channels, 23 and cooperative systems 24‐26 …”
