摘要
在分析现有安全定位方法及其特点的基础上,提出一种基于簇头检测、结合对称加密和非对称加密的安全定位协议,引入质心法对定位结果进行校正。仿真结果表明该定位协议具有较高的定位精度,并能有效地抵御恶意节点的攻击。
Based on the analysis of known secure positioning methods and their shortcomings, this paper proposed a new and secure location protocol by cluster head detection as well as using the asymmetric encryption and symmetric one. Furthermore, it used centroid method to calibrate the positioning data. The simulation results show that the proposed locating protocol experiences a high precision of location and it can defense the attack of malicious nodes very well.
