Abstract
The paper derives the detection probability of cooperative spectrum sensing (CSS) algorithms with energy harvesting. There are three phases with the same duration. The first phase is the energy harvesting phase done by primary user (PU) and relay nodes. They harvest energy from radio frequency (RF) signal received from node H. In the second phase, PU transmits its signal that will be received by relays. In the last phase, a selected relay amplifies the PU signal to a fusion center (FC) where spectrum sensing is performed using the energy detector. Our analysis is valid for opportunistic amplify and forward (OAF), partial (PRS) and reactive relay selection (RRS). A Nakagami fading channel is assumed between all nodes.
