The 3D Localization Mechanism for Wireless Sensor Networks Based on Mountainous Terrain
摘要
Abstract
This paper presents a non-dimensional distance wireless sensor network localization algorithm based on closer points projection correction which use the mountainous terrain mesh data for the problem that the localization error is large when 3D DV-hop algorithm is carried out in the actual terrain. After get the location of a node by using 3D DV-hop algorithm,search three points near the location of the node which is non-collinear and on the mountain-ous terrain mesh and make the node project toward the surface which is determined by the above three points. Pro-jection point is the node’s location after correction. Multi-scene experiments show that this method can greatly re-duce the position error.关键词
