In order to solve the problem of node location in 3D space WSN (Wireless sensor network), this article summarizes the structure and characteristics of WSN, then uses weighted centroid algorithm to estimate the location, designs a new non-ranging 3D node location algorithm for wireless sensor network, and gives the theoretical basis and implementation steps of this algorithm design. The algorithm does not need to measure the actual distance between nodes, but only needs the anchor nodes to broadcast their own beacon information, and the unknown nodes within the one-hop communication range of the anchor nodes receive and store the monitored beacon information, and estimate their own positions according to these information. The final simulation results show that, compared with the existing 3D localization algorithm based on non-ranging, there is no need for unknown nodes to communicate with each other, which has less communication overhead and does not depend on the proportion of anchor nodes. And it is robust to the network topology. As a non-ranging positioning algorithm, its positioning error is only about 15% in the set 3D space.
