Performance Analysis of Multihop Multirelay Multiuser CRNs with Energy Harvesting

This paper studies the performance of multi-hop multi-relay multiuser cognitive radio networks (CRNs), where the relay nodes harvest energy from a dedicated power beacon (PB) for data transmission. The PB is equipped with multiple antennas and employs maximum ratio transmission (MRT) to enhance the energy transfer efficiency. The sequence relay selection is applied for the proposed network to improve the reliable communication and network performance. The system performance in terms of outage probability (OP) is derived over Nakagami- m fading channels and validated via Monte Carlo simulations.
