CREATION AND APPLICATION OF A SENSOR NETWORK IN THE INFORMATION SYSTEM OF ENERGY ACCOUNTING OF A RESIDENTIAL COMPLEX

The article is devoted to a comprehensive study of the possibilities of using wireless sensor networks for energy consumption metering in residential complexes. The existing solutions are analyzed, appropriate mathematical models are developed, and a simulation experiment is conducted to evaluate the effectiveness of the proposed routing and network self-organization algorithms. The dependence of the duration of operation, stability, and throughput of a wireless sensor network on the ratio of coverage and communication radii is analyzed. A way to improve the accuracy of monitoring the energy consumption system of a neighborhood by researching and developing an information system for accounting for electricity consumption is found. The technical requirements of the network organization to the system and components of the neighborhood energy management system are considered, recommendations for the installation of the main components and their configuration are given, and installation diagrams are presented. The clustering algorithm for wireless sensor networks is improved, which is characterized by the integrated use of the previously known combined forecasting criterion and the value of the suitability of the sensor node to act as the master, which, due to the integrated use of the above values, provides a longer life cycle and an increase in the duration of the stability period compared to the known algorithms. The study of the BSM of a 5-storey building of the central gateways of the building with the selection of the main gateway (node) and the main gateways of the houses of the neighborhood was carried out. To obtain a positive result, the network clustering method was applied using the Kohanen layer and neural networks. This work was carried out to increase the life cycle of the WSN, which was proved in theoretical studies.
