The key layers of IoT architecture

摘要

The IoT architectures proposed in the literature and which can be deployed in a Cloud environment are diverse and multiple. These architectures are organized in several layers that differ in terms of functionality and number. It is therefore necessary to analyze these architectures and their layers in order to identify the key layers to define a complete and exhaustive architecture. This paper presents the result of the analysis of the different IoT architectures in a Cloud environment, proposed in the literature, and thus allows us to identify initially twelve layers cited in the thirty-two architectures studied. The results of this analysis show that six key layers are relevant to build a new reference architecture of an IoT system in a Cloud environment.
