基于RSS无源被动定位算法的WSN研究
A study of WSN based on RSS passive positioning algorithm
摘要
Abstract
In the WSN with a limited communication capability and energy,a high-precision passive location prob lem is proposed based on the RSS positioning method without additional hardware costs.First,the whole network is clustered,the target source position is estimated by the least-squares method in clusters,and then the estimation re sult is uploaded to the sink node through the cluster head node.Secondly,the estimation results of each cluster are fused at the sink node to obtain the final positioning solution.The simulation results show that the method can realize the same positioning accuracy when using a small number of nodes to participate while using all nodes.关键词
