Abstract: Aiming at the multi-hop transmission network with wireless energy harvesting technology, the path selection problem of multi-hop and multi-path transmission in a full-duplex relay network with multiple eavesdroppers and multiple power nodes is proposed. Firstly, the proposed system model performs information transmission in the scenes of multiple eavesdroppers and power nodes, and selects the best path between the source transmitter and receiver as the data transmission path. Secondly, in order to enhance the performance of the system, the relay collect energy from the radio frequency signal sent by the power node and use the obtained energy for data transmission of the next hop. Finally, the accurate expression of the end-to-end outage probability of the proposed method under Rayleigh fading channels is derived. The Monte Carlo simulation fits the theoretical analysis curves well, indicating the correctness of the theoretical derivation and the superiority of the performance of the proposed method.
