According to the characteristics of underwater sensor networks, the layout of underwater sensor nodes is studied. The model of event-driven sensor nodes layout in underwater three-dimensional space is established, and the algorithm of event-driven three-dimensional underwater sensor node layout is optimized. The simulation results show that the proposed algorithm can autonomously trend and cover the events of the sensor nodes, and achieve the matching of sensor node distribution density and event distribution density. The proposed algorithm has the advantages of low complexity, low computational complexity and fast convergence.
