Itskovich V. Information technologies for monitoring the parameters of the ecological state of the industrial city

The object of research is the interaction processes of devices connected to the network based on energy-efficient long-range LoRaWAN protocols. The purpose of the work is the development of information technology for the study of parameters of the state of the environment in the city of Kyiv. The work uses general scientific and special approaches, modern methods for creating and organizing networks based on wireless energy-efficient technologies. Models and approaches to the use of the Internet of Things in the development of a "smart city" are based on the principles of probability theory and mathematical statistics, a systematic approach to solving complex problems, the principles of logic algebra and methodological recommendations for project management in the information and telecommunications sphere. The work also uses other research methods in applied application and to justify the set tasks. Novelty: for the first time, a set of system requirements was defined for the implementation of information technology for the study of environmental parameters of a large city with the construction of an information model of the management process of a modern city, taking into account the time criterion; for the first time, a service was developed for receiving information from donors for subsequent processing and presentation through dashboards using the method of information convolution; received further development of the method of recursive copying of data for informing and monitoring the status of the object of observation; for the first time, an approach to building a model of the optimal number of transmitters of the monitoring system for emergency notification was developed for the application of this model in the development of information technology for emergency and emergency notification (using Bellman's functional equation). The results of the research were used: in the work of the specialized utility company "Kyivteleservice", which is the provider of the LoraWAN network and all components of the Internet of Things in the city of Kyiv, to improve the mechanism of surveying information providers; in the work of the Municipal Enterprise "Main Information and Computing Center" of Kyiv, to improve data processing services. The scope of use is the study of parameters of the state of the environment in the city of Kyiv based on the LoRaWAN specification.
