Outage analysis for simultaneous wireless information and power transfer in dual-hop relaying networks

Energy harvesting (EH) is believed to be a promising technology in next generation wireless networks due to its potential to extend the working time for uncharged nodes and improve the user experience. We investigate the outage performance of dual-hop decode-and-forward relay networks, where EH from wireless signals is considered at the relay node. Then, we derive the cumulative distribution function of the received SNRs. We also formulate the relationship among the outage probability, full EH slots and the power splitting factor by deriving the asymptotic expressions of the outage probability of our system. Simulation results closely match with our theoretical analysis.
