Report content:Based on the analysis of typical underwater sensor network localization algorithms proposed presently, the network model in underwater 3D space is described. Since the positioning performance of traditional positioning algorithms are incapable to meet the requirements of some applications, an improved multi-anchor node security cooperative positioning algorithm according to trust mechanism and cooperation and the positioning mechanism of the anchor node and the upgrade anchor node in the two-hop range of the ordinary node is proposed. The algorithm not only includes the existing anchor node to locate the ordinary node and iterative position, but also improves the 3D Euclidean distance estimation method and proposes the communication mechanism and voting mechanism to determine the coordinates of common nodes. At the same time, combined with the idea of DV-hop localization algorithm, the distance from ordinary node to two-hop anchor node is estimated, and some common nodes with difficult location information are located.
