Summary This work investigates the dual impacts of co‐channel interference (CCI) on radio frequency (RF) energy harvesting (EH)‐enabled cooperative cognitive radio network (CCRN). CCRN is considered to be worked following overlay mode of spectrum sharing technique. One pair of cellular nodes are considered as primary users (PUs), and a pair of Internet‐of‐Things devices (IoDs) are considered as secondary users (SUs) of CCRN. IoDs are used to help the communication between cellular node and in benefit of that the devices can access the cellular spectrum. In one hand, the effect of CCI from different sources may deteriorate the received signal‐to‐noise ratio (SNR) at IoDs, and on the other hand, scavenge of energy at IoDs from RF signal of CCI may improve the transmission of information from IoDs. Hybrid power time switching (HPTS) technique is adopted in the proposed model for harvesting energy from RF signals at IoDs following simultaneous wireless information and power transfer (SWIPT) principle. The closed form expressions of both PU and SU outage are derived to analyse the performance of two different networks. The joint effects of both power splitting and time switching factors on both PU and SU outage are shown in simulation results. The outage performances of both PU and SU networks with respect to different interference‐to‐noise (INR) level and transmission power are also shown in the results. The performance of the proposed system is found as better than the previous work on similar network architecture.

“…In addition, the combination of these two protocols has also been applied in the literature to increase the amount of harvested energy and the performance of SWIPT systems. Various works such as [28][29][30] demonstrated that PS protocol can provide better secrecy outage probability (SOP) and ergodic secrecy rate than TS protocol. However, the throughput of TS protocol outperforms that of PS protocol at relatively low signal-to-noise-ratio (SNR) and high trans-mission rate [31].…”

In this paper, we evaluate the performance of a vehicle-to-vehicle (V2V) system where full-duplex relay (FDR) harvests the energy from source and uses decode-and-forward (DF) protocol to forward data from source to destination. Unlike existing works about FDR systems, we consider the scenario that both relay and destination are moving vehicles, leading to the channel between relay and destination characterized by double (cascade) Rayleigh fading. We successfully obtain the closed-form mathematical expressions of the outage probability (OP) and throughput of the considered energy harvesting- (EH-) FDR-V2V system. Based on these expressions, the system performance is investigated through various scenarios. Numerical results indicate that the performance of the considered system is reduced compared with that of the system over Rayleigh fading channels. We also observe that there is an optimal EH time duration that minimizes the OP and maximizes the throughput. This value depends on the transmission power of source. Furthermore, the OP goes to outage floor faster due to the impact of the residual self-interference (RSI), especially when RSI is high. All analysis results are verified by Monte-Carlo simulations.
