Abstract: At present, most of the researches on sensor network deployment are mainly focused on two-dimensional(2D) planes and three-dimensional(3D) full-space areas. However, many real-world application fields are a complex 3D surface. The existing coverage methods cannot achieve good results. This paper studies the deployment method of 3D surface sensor networks, and proposes a 3D surface multi-mobile node sensor network deployment algorithm. A hybrid sensor network composed of static nodes and dynamic nodes is used to estimate the position and area of the coverage hole from the static nodes. The coverage holes are sequentially repaired by mobile nodes. Simulation results show that the final network coverage rate of the algorithm reaches 99%, which is 6 percentage points higher than the 3DGA algorithm and 8.5 percentage points higher than the Delaunay algorithm, while reducing overall network energy consumption.
