“…Rayleigh fading channels have been utilized for studies about the adaptive relaying protocol of twohop amplify-and-forward (AF) relaying networks with exceptional throughput performance [9], [10]. Besides, in [11] where the outage probability (OP) of decode-and-forward (DF) PSR system was analyzed, we can see that EH relaying network is more beneficial than conventional networks.…”

Employing simultaneous information and power transfer (SWIPT) technology in cooperative relaying networks has drawn considerable attention from the research community. We can find several studies that focus on Rayleigh and Nakagami-m fading channels, which are used to model outdoor scenarios. Differing itself from several existing studies, this study is conducted in the context of indoor scenario modelled by log-normal fading channels. Specifically, we investigate a so-called hybrid time switching relaying (TSR)-power splitting relaying (PSR) protocol in an energy-constrained cooperative amplify-and-forward (AF) relaying network. We evaluate the system performance with outage probability (OP) by analytically expressing and simulating it with Monte Carlo method. The impact of power-splitting (PS), time-switching (TS) and signal-to-noise ratio (SNR) on the OP was as well investigated. Subsequently, the system performance of TSR, PSR and hybrid TSR-PSR schemes were compared. The simulation results are relatively accurate because they align well with the theory.

“…In [10], the performance of two and three time slot transmission schemes in amplify-and-forward (AF) two-way relaying networks was investigated, where the authors proposed two new protocols: so-called power time splitting-based twoslot and power time splitting-based three-slot . Meanwhile, the authors in [10] continued their study on the throughput performance for two, three and four time slot transmission schemes for AF two-way relaying networks [11]. Regarding bit error rate (BER) performance, the sum BER performance of (AF) EH twoway relaying networks was evaluated deploying TSR protocol [12] while the work in [13] derived an exact closed-form expression for average BER of a selection combining scheme for a cooperative system using an AF relay with simultaneous wireless information and power transfer.…”

Because of the short battery life of user equipments (UEs), and the requirements for better quality of service have been more demanding, energy efficiency (EE) has emerged to be important in device-to-device (D2D) communications. In this paper, we consider a scenario, in which D2D UEs in a half-duplex decode-and-forward cognitive D2D communication underlying a traditional cellular network harvest energy and communicate with each other by using the spectrum allocated by the base station (BS). In order to develop a practical design, we achieve the optimal time switching (TS) ratio for energy harvesting. Besides that, we derive closedform expressions for outage probability, sum-bit error rate, average EE and instantaneous rate by considering the scenario when installing the BS near UEs or far from the UEs. Two communication types are enabled by TS-based protocol. Our numerical and simulation results prove that the data rate of the D2D communication can be significantly enhanced.

“…Later, Ojo and Salleh [17] proposed a namely hybrid power-time splitting based relaying protocol (HPTSR) and analyzed its throughput performance in AF and decode-and-forward (DF) scenarios. The throughput of two-way AF relaying networks in three different schemes namely two, three, four-time-slot (2TS, 3TS, 4TS) was investigated in [18]. Khan et al [19], one of the most recent studies, two relay selection schemes so-called joint relay power allocation and selection scheme (JPASS) and ratio selection scheme (RSS) were proposed and proven with remarkably better average sum-throughput in comparison with conventional schemes.…”

Most of the existing studies on energy harvesting (EH) cooperative relaying networks are conducted for the outdoor environments which are mainly characterized by Rayleigh fading channels. However, there are not as many studies that consider the indoor environments whereas the state-of-the-art internet of things (IoT) and smart city applications are built upon. Thus, in this paper, we analyze a namely hybrid time-power splitting relaying (HTPSR) protocol in a full-duplex (FD) decode-and-forward (DF) battery-energized relaying network in indoor scenarios modelled by the unpopular log-normal fading channels. Firstly, we formulate the analytical expression of the outage probability (OP) then the system throughput. Accordingly, we simulate the derived expressions with the Monte Carlo method. It is worth mentioning that in our work, the simulation and the theory agree well with each other. From the simulation results, we know how to compromise either the power splitting (PS) or the time splitting (TS) factors for optimizing the system performance.
