Abstract: This paper provides the packet error probability (PEP) and throughput of cognitive radio networks (CRN) with energy harvesting (EH) and adaptive transmit power (ATP). Multihop multibranch relaying is considered and only the best amplify and forward (AF) branch is activated. Our analysis is valid forEHsystem using harvested energy from radio frequency (RF) signals. The powers of secondary nodes are adaptive so that interference to primary receiver P_R is lower than interference threshold I. We also choose the harvesting duration to enhanced the end-to-end (e2e) throughput.
