摘要
Abstract
The estimative region of unknown node cannot be obtained accurately in existing range-free localization algorithms. To address this problem, a new distributed grid scanning localization algorithm is proposed for Wireless Sensor Network(WSN). The initial estimative region of each unknown node is calculated, and the initial region is divided into a grid array, where the validity of each grid is judged. The centroid of the field of validity grids is regarded as the estimated position of the unknown node. Simulation results show that, comparing with the Distributed Localization Estimating(DLE) algorithm, the accuracy of the proposed algorithm is improved more than 20%.关键词
