Researchers have studied instances of power line technical failures, the significant rise in the energy loss index in the line connecting the distribution transformer and consumer meters, and the inability to control unauthorized line connections. New, innovative, and scientific approaches are required to address these issues while enhancing the reliability and efficiency of electricity supply. This study evaluates the reliability of Internet of Things (IoT)-aided remote monitoring systems specifically designed for a low-voltage overhead transmission line. Many methods of analysis and comparison have been employed to examine the reliability of wireless sensor devices used in real-time remote monitoring. A reliability model was developed to evaluate the reliability of the monitoring system in various situations. Based on the developed models, it was found that the reliability indicators of the proposed monitoring system were 98% in 1 month. In addition, it has been proven that the reliability of the system remains high even when an optional sensor in the network fails. This study investigates various IoT technologies, their integration into monitoring systems, and their effectiveness in enhancing the reliability and efficiency of electrical transmission infrastructure. The analysis includes data from field deployments, case studies, and simulations to assess performance metrics, such as accuracy, latency, and fault detection capabilities. [ABSTRACT FROM AUTHOR]

This paper evaluates the reliability of the information system for identifying mobile devices by the IMEI code (International Mobile Equipment Identifier). A system for identifying mobile devices by IMEI code is presented, which includes a database that is accessible both locally and remotely. The system allows collecting, storing, and processing information about all devices imported into the country and used in the country. Indicators for calculating the reliability of the information system are selected. Only server hardware with software is considered, and communication lines or other devices connected to the server are not considered. The situation is considered when the database of IMEI-codes and the software part are located on the same equipment, additional redundancy or duplication of nodes, elements, modules are not provided. A method for calculating the reliability of the “server - software” complex is proposed and analytical expressions for calculating the reliability are developed. The obtained results indicate good reliability and fault tolerance of the developed information system.
