This letter analyzes the performance of simultaneous wireless information-and-power transfer (SWIPT) in a cognitive radio sensor network (CRSN) under Nakagami-m fading. A pair of sensor nodes (SNs) is considered in which one SN facilitates relay cooperation for communications between two primary users (PUs). In return, SNs make use of primary users' signals for energy harvesting (EH) and realize their own communications. In such a network, bidirectional communications between the two PUs and unidirectional information exchange between the SNs can be performed in three phases. A power splitting (PS) based approach is adopted for enabling SWIPT. The relaying SN applies an amplifyand-forward (AF) protocol to broadcast primary and secondary signals, whereas the PUs perform selection combining to access the active direct link. Accurate expressions of the outage probability (OP) and throughput are derived for the primary system by considering a nonlinear energy harvester at the relaying SN under Nakagami-m fading.Index Terms-Cognitive radio sensor networks, SWIPT, wireless powered sensor networks, Nakagami-m fading.

“…In addition, the improvement regarding the secondary data outage probability was shown due to the interference from the primary network. In [21], the secondary data outage probability is investigated in an underlay DF relay cognitive network where a secondary relay harvests energy from the secondary source to transmit to the secondary destination. An interference constraint is imposed at PR, and an EH constraint is imposed at the secondary relay.…”

In this paper, we study a cooperative cognitive radio network (CCRN) where the secondary user-transmitter (SU-Tx) assists bi-directional communication between a pair of primary users (PUs) following the principle of two-way relaying. In return, it gets access to the spectrum of the PUs to enable its own transmission to SU-receiver (SU-Rx). Further, in order to support sustainable operation of the network, SU-Tx is assumed to harvest energy from the RF signals received from the PUs, using the technique of simultaneous wireless information and power transfer (SWIPT). Assuming a decode-and-forward behaviour and power-splitting based relaying protocol at SU-Tx, closed form expressions for outage probability of PU and SU are obtained.Simulation results validate our analytical results and illustrate spectrum-efficiency and energy-efficiency advantages of the proposed system over one-way relaying. KEYWORDSCooperative cognitive radio network, simultaneous wireless information and power transfer, two-way relaying, decode-andforward relaying.
