In this paper, we analyze the throughput performance of incremental relaying using energy harvesting (EH) decode-and-forward (DF) relays in underlay cognitive radio networks (CRNs). The destination combines the direct and relayed signals when the direct link is in outage. From the derived closed-form expressions, we present an expression for the powersplitting parameter of the EH relay that optimizes the throughput performance. We demonstrate that relaying using EH DF relays results in better…

Performance of Two-Hop Cooperative Cognitive Networks with an Energy Harvesting Relay

It is established that there exist optimum values of EH parameters that result in maximum throughput with TS and PS EH protocols and closed-form expressions are derived for these in some special cases.

Throughput of Underlay Cognitive Energy Harvesting Relay Networks With an Improved Time-Switching Protocol

It is demonstrated that the proposed EH transmission scheme can yield better secondary throughput performance as compared to that achieved by an optimal EH Transmission protocol using a fixed charging duration, while at the same time eliminating the need for feedback of channel estimates.

A two-hop underlay cognitive radio network in which the secondary relay harvests energy from the secondary source before commencing two- hop transmission is considered, which allows for charging time to be optimally varied.

Outage Performance of Cognitive Relay Networks With Wireless Information and Power Transfer

The developed analytical results demonstrate that the use of SWIPT will not cause any loss in diversity gain, but the outage probability achieved by the SWipT-CR scheme asymptotically decays as log SNR/SNR, whereas a decaying rate of 1/ SNR is achieved by a conventional CR network.

Outage Analysis for Underlay Cognitive Networks Using Incremental Regenerative Relaying

An underlay cognitive network where the quality of service (QoS) of the secondary link is maintained by triggering an opportunistic regenerative relaying once it falls under an unacceptable level is investigated.

Relay selection and outage analysis in cooperative cognitive radio networks with energy harvesting

This paper considers a CCR network with energy harvesting in which multiple secondary transmitters are able to harvest energy from the received signals to serve their own receivers and primary transmitters and proposes two relay selection schemes, i.e., single relay selection and multiple relay selection, by considering harvested energy.

Energy efficient switching between data transmission and energy harvesting for cooperative cognitive relaying systems
