The Analysis of Databases Suitable for IoT Environment
Kohout, Petr ; Vrána, Roman (referee) ; Kořenek, Jan (advisor)
In recent years, the volume of data stored in applications of all types has increased. As the volume of data grows, the demands on databases increase. The classic relational databases are no longer suitable. Therefore, it is switching to new, non-relational storage (called NoSQL). During this work, NoSQL databases focusing on processing large data volumes were analyzed and compared for their performance and system requirements. In addition, requirements for new sensor data storage for IoTCloud project were specified. Driver for database Cassandra was implemented and integrated into the IoTCLoud project.

Air Quality Analysis in Office and Residential Areas
Tisovčík, Peter ; Korček, Pavol (referee) ; Kořenek, Jan (advisor)
The goal of the thesis was to study the indoor air quality measurement focusing on the concentration of carbon dioxide. Within the theoretical part, data mining including basic classification methods and approaches to dimensionality reduction was introduced. In addition, the principles of the developed system within IoTCloud project and available possibilities for measurement of necessary quantities were studied. In the practical part, the suitable sensors for given rooms were selected and long-term measurement was performed. Measured data was used to create the system for window opening detection and for the design of appropriate way of air change regulation in a room. The aim of regulation was to improve air quality using natural ventilation.
