In this project propose the performance of wireless powered cognitive radio sensor networks (CRSNs) in the presence of hardware impairments (HIs). Wireless powered CRSN can be a potential solution to address spectrum scarcity and power shortage in the wireless sensor networks. Herein, the spectrum sharing is exploited to compensate for the spectrum scarcity, whereas the radio frequency energy harvesting technique is utilized to prolong the lifetime. Specifically, we consider a CRSN scenario with two primary nodes and a pair of sensor nodes (SNs). The SNs are assumed to be low-cost devices in view of the Internet of Things infrastructure. Consequently, they are more prone to suffer from different HIs. For evaluating the system performance, we obtain accurate expressions of the outage probability and the system throughput over Nakagami-m fading in the presence of transceiver HIs.
