基于区域分割的二次质心定位算法
SECONDARY CENTROID LOCALISATION ALGORITHM BASED ON REGION SEGMENTATION
摘要
Abstract
In order to solve the problem of the centroid localisation algorithm leading to considerable error when the anchor nodes are uneven distributed,we propose an improved centroid localisation algorithm.It uses the results of initial centroid localisation to replace the beacon node farthest from the unknown node within the unknown node communication radius,and makes secondary localisation afterwards to reduce the phenomenon that the estimated location of the unknown node biases the distant beacon node due to the uneven distribution of the beacon nodes.Simulation results show that compared with traditional ordinary centroid localisation algorithm,the secondary centroid localisation algorithm gains greater improvement in localisation precision.关键词
