基于线性回归的无线传感器网络加权质心定位算法
Linear-regression-based Weighted Centroid Localization Algorithm in Wireless Sensor Network
摘要
Abstract
On the basis of the establishment of mathematical models, this paper proposed anew localization algorithm for wireless sensor network--linear-regression-based weighted cen-troid localization algorithm. This algorithm has improved weighted centroid localization algorithm by using the hops between nodes, centering and calibrating nodes' position by using linear regression mathematical model. Finally, the algorithm corrected the position by using certain parameters. After using matlab for simulation and comparing with the original centroid localization algorithm, the new algorithm's average localization error was found to drop by more than half and the localization ratio was increased to close to 1 in the case of anchor node in low density.关键词
