摘要：Localization is a fundamental and essential issue for wireless sensor networks (WSNs). In this paper, a three-dimensional localization scheme, iterative calculation of secondary grid division localization scheme (ICSGDLS), was proposed for wireless sensor networks. In this scheme, forty beacon nodes and five hundred unknown sensor nodes were randomly deployed in a cube, which is divided into smaller cubes twice. The position information of unknown nodes could be got by iteratively calculating the centroid of smaller cubes. Simulation showed that the scheme could estimate the position of a node more accurately at a less cost. The average location error could be decreased by 67.7%.
