一种基于传感器网络的水污染源质心定位算法
A Centroid Algorithm for Water Pollution Source Localization in Sensor Networks
摘要
Abstract
In the pollution source localization by using sensor networks,analytic localization algorithms depending on diffusion models are always adopted. However,there are errors in the complicated numerical computation,and the diffusion models which are proposed under ideal assumptions bring errors in the localization. In some special cases, there are no explicit diffusion models and thus the localization methods related to diffusion models cannot be ap-plied. To make up for the deficiencies of water pollution source localization methods based on physical models in sensor networks,a centroid localization algorithm independent of diffusion models is proposed. In the algorithm,the area where the pollution source exists is determined firstly;the centroid of the area is calculated secondly. The posi-tion of the centroid is the source location. To solve the centroid localization problem,the particular solutions consid-ering the concentration contours are given. The experiment results show the advantages of the proposed localization methods comparing with the algorithms relying on diffusion models and the coarse localization algorithms. The effec-tiveness of the proposed algorithm is proved.关键词
