Internet of Things: Hierarchy of Smart Systems

Abstract

This paper is the first attempt to carry out the system analysis of Internet of Things as a global and booming object. The hierarchical IoT division into subsystems has been made. The main function executed by certain subsystem is chosen as a criterion of division. The scale of degrees of risks, which can emerge because of negative factors, arising in each of the subsystems is offered. The scale of degrees of risks allows to assess the own risks and cross risks in IoT subsystems. According to the experts involved in the process of assessment the scale is able to indicate the risks emerging at all IoT hierarchy levels. The authors show that the biggest risks emerge in the highest-level system – the one of Internet of Things as a global and planetary object. The directions of the further research of IoT system risks are formulated
