Internet of Things made his first appearance in the eighties, when was connected to the Internet an adjusted vending machine. The concept of the Internet of Things started with his popularization back in year 1999. Since then, the Internet of Things spread his popularity and now is present almost on every step. There are predictions that there will be around 30 billion devices connected to Internet by 2020.
With the boom of the Internet of Things has emerged the need for guidelines for the design of systems and devices in this field, because systems and devices must meet certain requirements for the Internet of Things such as providing connectivity and communications, device management, interoperability, scalability, data collection and analysis and security. Guidelines for the design have emerged in reference architectures and models and their purpose is to serve as a guide for system engineers for the Internet of Things when designing such systems. There is a large number of reference architectures but in the forefront are the Industrial Internet Reference Architecture (IIRA), architectural reference model IoT-ARM, reference architecture WSO2, reference architecture Azure and reference model ITU-T.
This thesis contents a review and analysis of reference architectures and models with the description and presentation of certain areas of the Internet of Things by selecting the preferred reference architecture for the design of the system for a specific application area. Moreover, the thesis presents a description of the basic features of the Internet of Things and a short presentation of the vision of the Internet of Things in the near future.
