电力物联网下无线传感器网络位置隐私保护方法研究

摘要

This paper conducted a brief introduction to the concept of wireless sensor networks and what they can do in internet of things of power system, and pointed out the privacy issues in WSNs. Secondary! An overview of the location privacy was introduced, and an adversary model was given. Then, several location privacy preservation technologies were introduced for source node and sink node respectively, analyzed and compared their performance. In the last, some suggestions were proposed on the concern in location privacy preservation technologies of WSNs in internet of things of power system.%首先对无线传感器网络的概念及其在电力物联网中的应用进行了简单的介绍,指出了无线传感器网络中存在的隐私问题；其次针对位置隐私保护进行了概述,并给出了攻击者模型；接下来,分别介绍了几种源节点位置隐私保护和汇聚节点位置隐私保护技术,并对它们的性能进行了分析和比较；最后,我们对电力物联网中的无线传感器网络位置隐私保护技术所需考虑的问题提出了见解和建议.
