一种基于残差分析过滤的安全定位算法
A secure localization algorithm based on residual analysis filtration
摘要
Abstract
During the process of localization in the wireless sensor network,the appearance of malicious anchor nodes will destroy the performance of network positioning.In order to solve this problem,a new wireless sensor network security algorithm is proposed,which based on the characteristics of malicious anchor nodes and the residual problem in location calculation.Firstly,a distance-based security location model is established.Then the residual problem in the network location is analyzed,and the malicious anchor nodes in the network are filtered out by the characteristic of residual.Finally,the unknown nodes are realized high-precision positioning result by the information of residual anchor node and gradient descent method.The simulation results show that the proposed algorithm can achieve relatively high positioning accuracy under a variety of performance indexes,and can maintain high positioning performance even under intensified malicious attacks.So this algorithm can not only effectively resist the malicious attack on the node location,but also significantly enhance the security of network localization.关键词
