基于几何学的无线传感器网络节点定位算法研究
Research on Wireless Sensor Network Node Localization Algorithm Based on Geometry
摘要
Abstract
It was the first time that the gradient concept of geometry was applied to the wireless sensor network localization algorithm.The method for analyzing the position relationship between anchor nodes has been investigated and given by the location of geometric algorithm.In two-dimensional plane,locating a target node requires three anchor nodes which have a significant selected position.If the selected anchor node doesn't fit,this cannot locate the position of unknown node.Therefore,before localization,the optimum anchor node combination should be selected in accordance with the proposed scheme,and then locating these nodes can improve the accuracy of localization.This method provides reliable basis for the selection of anchor nodes in localization algorithm,and then improves location accuracy and location coverage.关键词
