Abstract

Aiming at the poor positioning accuracy of the APIT positioning algorithm in wireless sensor networks, this paper proposes an APIT positioning algorithm 3DTC-APIT based on tetrahedral centroid cutting. First, the algorithm reduces the occurrence of misjudgment by setting the node counter. Second, use the centroid of the tetrahedron to cut the node location area multiple times to solve the node coordinates to be located. Finally, the node to be located whose position has been determined is added as a temporary anchor node to assist other anchor nodes in positioning. The simulation results show that compared with the comparison algorithms, the algorithm 3DTC-APIT can better improve the positioning accuracy and positioning coverage of nodes.
