基于自适应迭代搜索的三维质心定位算法
Adaptive Iterative Search Based on Centroid Localization Algorithm for Three-dimensional Space
摘要
Abstract
The adaptive iterative search based on centroid localization algorithm is proposed based on the analysis of cancroids localization algorithm and received signal strength indicator model.First,the initial search step of unknown nodes is figured out,through multiple iterations,updating the search points and search step,the accurate location of nodes is got.This proposed algorithm has better ability of self-adaptive which can improve the accuracy of locating node,automatically adjust the range of search step,and have small number of times to iterate.The influence of different communication radius and density of distribution of reference nodes on location error was analyzed.The results show that the new approach performs well with high location accuracy and strong stability,and it is suitable for localization in three-dimensional space of wireless sensor network.关键词
