Development of an IoT network infrastructure based on a sensor network of distributed sensors for measuring radiation pollution using a multi-level architecture

Abstract

Approaches to creating a network infrastructure based on a network of distributed sensors for radiation monitoring of environmental pollution have been developed in the article. Fundamental solutions IoT is characterized as integral part of the peoples’ live not only in Ukraine but a whole world. The article analyzes and develops schematic diagram and unified approaches to building a full-fledged system of distributed sensors that can be wirelessly connected to each other. By using cloud services, a new level of interaction between the user and the application has been reached. Autonomous network management should provide for various aspects such as: self-management, automatic configuration, automatic troubleshooting, as well as power management. These prerequisites are essential for this set of devices. The system is responsible for communication between the user and applications, and above all for creating secure communication channels, because the issue of cybersecurity is of extreme importance and data breaches can cause environmental risks and huge expenses. The article examines the ability to respond to location, provide communication between devices and users and meet the security needs of the equipment installation. Individual parts of the IoT system, which usually work automatically, allow authorized persons to provide the necessary configurations and measurements. The multilevel nature of IoT for managing transmission, reception, and data processing has been considered. The article supplements previous articles on the topic of full-fledged sensor network architecture where the modern microcontrollers are used. Using modern protocols makes it possible to present this system on the world market. Communication networks transmit data received from connected devices, as well as program instructions to other parts of the system; therefore providing opportunities for reliable and efficient data transmission. The IoT network infrastructure can be implemented through existing networks and data exchange protocols, such as TCP/IP, and on currently developed networks, such as next-generation networks (NGN). The latest approaches to system management are applied.
