DB: A Developed 3D Positioning Algorithm in WSN Based on DV-Hop and Bounding Cube

In this paper, we come up with a new algorithm for node localization in three-dimensional wireless sensor networks, DB. Based on the two well-known algorithms, DV-Hop and Bounding Cube, DB uses the distance of known nodes and unknown nodes as the radius of the cubes which are used for centroid estimate, and then evaluate location of the unknown nodes according to the intersection of the cubes. And the results of the simulation proved that this algorithm is more accurate and less complex compared with DV-Hop and Bounding Cube, thus it can meet the demand on location algorithm better.
