Non-Linear EH Relaying in Delay-Transmission Mode over n-µ Fading Channels

Abstract

Energy harvesting is a technique to harvest energy from RF (radio frequency) waves. The RF signals have the ability to convey energy and information concurrently. The EH in cooperative relaying systems may increase the capacity and coverage of wireless networks. In this work, we study a dual-hop (two-hop) relaying. This system has three nodes: a source, a relay, and a destination. The source and destination have multiple antennas. We account a non-linear EH model and TSR (time-switchingbased relaying) protocol at the single-antenna relay node. We evaluate the system performance over η − µ fading channels. With a saturation threshold, a non-linear EH receiver restrains the harvested power. In the TSR protocol, the relay changes mode between the EH and information processing, by which a fraction of time is used with each process. The fading model η−µ incorporates some fading models as notable cases, viz., Nakagamim, One-sided Gaussian, Nakagami-q (Hoyt), and Rayleigh. The system performance is analyzed in terms of the average capacity and throughput for different saturation threshold power levels, divers antennas arrangements, and different parameter values of η and µ.

Performance Analysis of UAV Relay Assisted IoT Communication Network Enhanced With Energy Harvesting

“…Chen [23] analyzed the outage probability and throughput of AF systems for energy harvesting under the interference of relay and destination nodes. Hussain et al [24] studied the performance of a two-hop model system with multiple antennas in a κ-µ shadow fading channel. Badarneh et al [25] showed the performance of energy harvesting DF systems in generalized η-µ and κ-µ mixed fading environments with multiple nodes cooperation.…”

Average SER analysis of two‐hop WP DF relay system under κ−μ shadowed fading

“…Generalized − , − , and − shadowed fading models are considered in [29][30][31][32][33] to examine the performance of WP relay systems with EH at the relay node(s). To the best of our knowledge, no work on WP relay systems with EH at source node under consideration of the generalized fading models is reported in the literature.…”

Non-Linear Energy Harvesting Dual-hop DF Relaying System over n-µ Fading Channels

“…Integrating a dual-hop relaying system with wireless energy harvesting techniques can enhance the coverage capacity and network life-time [2], [3]. In a dual-hop wireless energy harvesting relaying network, the relay is an energy constrained device which harvests the energy through RF signals [4].…”

“…In a dual-hop wireless energy harvesting relaying network, the relay is an energy constrained device which harvests the energy through RF signals [4]. One of the well-known relaying methods is a decode-andforward (DF) relaying, in which relay decodes and sends the information to the destination [2]- [4]. Several authors have investigated the wireless energy harvesting in a DF relaying system [2]- [5], [7]- [13] (and references therein).…”

“…In the works [2]- [4] (and their references), for the dualhop energy harvesting DF relaying networks, a linear energy harvesting receiver was assumed. But, in reality, an energy harvesting circuit is non-linear owing to the non-linearity of the electronic components, i.e., inductors, capacitors, and diodes [7].…”
