一种抗独立攻击的WSN三维安全定位算法
A 3D Secure Localization Algorithm Resistant to Non-Coordinated Attack in Wireless Sensor Network
摘要
Abstract
To solve the problems about lower accuracy and lack of security of node location for wireless sensor net⁃work deployed in stereoscopic environments,a new three-dimensional secure localization algorithm is proposed by steepest descent method and Newton’s method. In this algorithm,firstly,the calculation method of unknown node lo⁃calization in three-dimensional space and the model of non-coordinated attack are presented. Secondly,it chooses the optimal anchor node data by using the steepest descent method and the detection technology of malicious anchor node. Then,combining with the Newton’s method,the algorithm achieves the fast and high-precision secure local⁃ization of three-dimensional space. The experimental results show that the algorithm can resist the non-coordinated attack in a dangerous environment effectively and do good advantages on the localization accuracy and localized rate of unknown node.关键词
