一种基于迭代优化的安全定位算法
A Secure Localization Algorithm Based on Iterative Optimization Method
摘要
Abstract
Because wireless sensor network nodes are often deployed in malicious environment,the node cannot get accurate location information,which leads to the destruction of network security.For the problem of secure location of wireless sensor networks in malicious environment,a new security localization algorithm based on Newton iteration method is proposed.Firstly,the security localization model is established,then the gradient vector is analyzed in the process of iteration,and the anomaly detection process is improved and optimized by using the differential threshold method.Finally,the unknown node is realized high-precision positioning result by residual information of anchor node and Newton iteration method,and further improving the node positioning accuracy.The simulation results show that Newton iterative method is better than gradient descent method in location application,and the optimized security location algorithm has better location accuracy and robustness.关键词
