The open, distributed, and dynamic nature of wireless sensor networks makes them vulnerable to network attacks. Meanwhile, the limited energy of nodes and the existence of selfish nodes will lead to a low packet delivery rate and high energy consumption. In order to solve these problems, a safety intelligent relay node selection algorithm based on EH-WSN is proposed. First, we implemented a solar replenishment model to predict the node's replenishment energy. Then, by establishing a relay node evaluation model, the node on the routing path is evaluated, and the node evaluation value is updated dynamically in route training based on an enhanced Q-Learning algorithm. The simulation results show that the proposed algorithm has good performance in terms of improving packet delivery rates and reducing the energy consumption of nodes.
