摘要
目前解决无线传感网节点安全的方式多种多样,无线传感器也将随着物联网的发展而呈现多样化.根据物联网传感层的特点和其特有的安全问题,本文提出了一种基于能量监测的信任评估方法来解决无线传感网节点的信任问题.该方法首先针对无线传感器能耗情况,创建了传感器能量监测机制;然后,根据监测能量机制中的监测信息,通过互相关系数方法分析计算,得出传感器所处的几种信任度;最后,对传感器进行信任评估,并给出评估结果.仿真对比结果表明,本文提出的方法具有较高的准确性.
At present all kinds of security methods are used to solve security problems of WSNs （wireless sensor networks）. Along with the development of Internet of Things, wireless sensors in sensing layer of Internet of Things will also be diversified. Therefore,according to the sensing layer＇s characteristics and its unique security problems of Intemet of Things, we propose a trust evaluation mechanism based on energy monitoring to solve the security issues of sensing layer. Firstly, this paper establishes an ener- gy monitoring mechanism of wireless sensors. Secondly, it uses the correlation coefficient method to calculate the data of energy monitoring and conclude the trust melric of sensors. Simulation results show that the lrust evaluation method of wireless sensors pro- posed in this paper has higher accuracy.
