## 1 Introduction  
Internet of Things (IoT) is considered a critical research area worldwide and has a significant impact on all activities in daily lives and industry [1; 2; 3]. However, because of numerous disadvantages, some industrial and civil aspects of IoT are difficult to achieve. Energy limitations are the most significant problem in the long-term operation of wireless networks. Prolonging lifetimes and battery recharging/replacement are not practical solution for wireless networks. Wireless energy harvesting (EH) using radio frequency (RF) is considered a promising solution for prolonging the operating time of devices in wireless, energy-constrained cooperative networks [4; 5; 6]. RF signals in EH wireless networks can transfer energy and information simultaneously. Cooperative networks are considered in connection with power sharing by helping the relay (R) between the source (S) and the destination (D) [6]. In EH cooperative networks, an energy-constrained R, by simultaneously harvesting energy and transferring information, helps maintain constant operation and connection without the use of external energy sources. The authors in [7] considered a dual-hop cognitive, inter-vehicular, relay-assisted communication system where all communication links are not line of sight, and their fading is modeled by the binary Rayleigh fading distribution. An analytic performance evaluation of the bit error rate (BER) of underlay decode-and-forward cognitive networks with the best relay selection over Rayleigh multipath fading channels was introduced in [8]. The authors in [9; 10] presented a general framework for modeling and evaluating the performance of dual-hop, decode-and-forward (DF) relaying schemes over independent and not necessarily identically distributed (INID) Nakagami-_m_ fading channels. The performance of dual-hop MIMO OSTBC transmission with multiple antennas employed at the transceiver and CSI-assisted AF relay over Nakagami-m fading is proposed in [11], and the performance of dual-hop, decode-and-forward relaying with relay selection (RS), analyzed over Nakagami fading channels, was studied in [12]. In our previous papers, we consider the EH over Rician fading channels. The titles of these papers are as follows: A Performance Analysis for Half-Duplex Bidirectional Sensor Networks under Hardware Impairments [12], Adaptive EH Relaying Protocol for a Two-Way Half Duplex System Network over Rician Fading Channels [13], Energy Harvesting-based Spectrum Access with Incremental Cooperation, Relay Selection, and Hardware Noises [14], and Performance Enhancement for EH Based Two-way Relay Protocols in Wireless Ad-Hoc Networks with Partial and Full Relay Selection Methods [15]. The problem of a two-hop EH cooperative relaying network was studied in [16]. In [17], a harvest-then-cooperate (HTC) protocol with AP points for S and R EH was investigated. The authors in [18] maximized the end-to-end achievable information transmission rate by assuming perfect channel state information (CSI) of the cooperative network with time switching (TS) and power splitting (PS) protocols. The authors in [19] investigated two-way relay beamforming optimization to maximize the achievable sum rate of simultaneous wireless information and power transfer (SWIPT) system with a full-duplex (FD) multiple-input multiple-output (MIMO), amplify-and-forward (AF) relay. To extend [19], the authors in [20] studied the joint optimization of two-way relay beamforming. Furthermore, the authors in [21] investigated SWIPT mechanisms in a relaying network with finite block length (FBL) codes. Moreover, the authors in [22] derived the theoretical symbol error probability (SEP) of cooperative systems with the best relay selection for Nakagami-m fading channels, and the authors in [23] proposed a novel DSTBC scheme with embedded adaptive DAF/amplify-and-forward (AAF) elements for data retransmission in multihop PLC networks with existing opportunistic listening (OL) protocols.
