摘要
针对物联网系统性能的评价一直没有统一的标准,提出物联网鲁棒性的概念并对其性能进行评估,同时选取系统性能指标。采用熵权法确定系统各指标的权重,并采用云模型理论实现评估指标数据和评语之间的不确定映射。仿真试验结果表明,利用云模型的评估方法可以较好地描述物联网鲁棒性的优劣,从而实现对物联网系统性能的整体评估,为物联网系统性能的评估提供了一种有价值的新思路。
The evaluation of the performance of Internet of things （IOT） is lack of uniform standard, aiming at this condition, the concept of robustness for IOT is proposed and the evaluation of performance is conducted, meanwhile the systematic performance indexes are selected. The weight of each index is determined by using entropy weight method ; and the uncertainty mapping between index evaluation data and commentary is implemented by using cloud model theory. The result of simulation experiment indicates that the evaluation method using cloud model can well describe the pros and cons of the robustness of IOT, this provides new valuable ideas for performance evaluation of IOT systems.
