Relaying Protocols for Wireless Energy Harvesting and Information Processing
TL;DR: The numerical analysis provides practical insights into the effect of various system parameters, such as energy harvesting time, power splitting ratio, source transmission rate, source to relay distance, noise power, and energy harvesting efficiency, on the performance of wireless energy harvesting and information processing using AF relay nodes.
Journal ArticleDOI
Relaying Protocols for Wireless Energy Harvesting and Information Processing
TL;DR: In this article, two relaying protocols, namely, time switching-based relaying (TSR) and power splitting-based relay (PSR), are proposed to enable energy harvesting and information processing at the relay.
Journal ArticleDOI
Wireless-Powered Relays in Cooperative Communications: Time-Switching Relaying Protocols and Throughput Analysis
TL;DR: It is shown that the proposed protocols outperform the existing fixed time duration EH protocols in the literature, since they intelligently track the level of the harvested energy to switch between EH and IT in an online fashion, allowing efficient use of resources.
Proceedings ArticleDOI
Throughput and ergodic capacity of wireless energy harvesting based DF relaying network
TL;DR: Through numerical analysis, the throughput performance of the overall system for different system parameters, such as energy harvesting time, power splitting ratio, and signal-to-noise-ratio (SNR), exceeds that of the TSR scheme for a wide range of SNRs.
Journal ArticleDOI
