针对具有无线能量采集技术的多跳传输网络，提出了全双工中继网络在有多个窃听者和多个功率节点场景下进行多跳多路径传输时的路径选择问题。首先，所提系统模型在有多个窃听者和功率节点的场景下进行信息传输，将源发射端和接收端之间的最佳路径作为数据传输路径。然后，为了增强系统性能，中继节点对功率节点发出的射频信号进行能量采集并利用所获能量来进行下一跳的数据传输。最后，推导出了所提路径选择方法在瑞利衰落信道下端到端中断概率的精确表达式，蒙特卡洛仿真和理论分析曲线拟合较好，说明了理论推导的正确性，以及所提方法具有性能上的优越性。

Path selection of multi-hop network secure transmission based on wireless energy harvesting

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.
