A MODEL OF A CORPORATE NETWORK BASED ON IOT TECHNOLOGIES OF AN ENVIRONMENTAL RESEARCH ENTERPRISE

Abstract

Significant environmental changes are being recorded around the world. Environmental changes are particularly noticeable in Ukraine, which is currently experiencing a war and an environmental disaster due to the destruction of the Kakhovka hydroelectric power station. Due to the war and the change in the Dnipro riverbed, population migration and business relocation are taking place, causing changes in the concentration and location of air emissions. As a result, requirements for the quality, quantity and scope of air quality studies are increasing. To meet the requirements for environmental research, as well as to increase the level of automation of data collection, storage, processing and semi-automatic generation of reports on data from stations and observation posts, the creation of a software and hardware information system is an urgent task. This study focuses on creating a model of the hardware part of the information system in the form of a network in Cisco Packet Tracer, which supports the integration of smart devices, for the environmental monitoring process. The object of this study is the process of modelling a corporate network. The subject of the study is modelling the architecture of a corporate network supporting IoT technologies using Cisco Packet Tracer. The purpose of the study is to recreate the model of an analytically calculated corporate network using Cisco Packet Tracer, which will allow testing the network in different modes of operation and forming a pool of recommended settings before its physical implementation. In the course of the study, the method of modelling a physical object in Cisco Packet Tracer was used and the addresses were practically distributed among local computing devices. The scientific novelty of the work lies in the fact that for the first time a model of a corporate network with support for IoT technologies of an environmental research enterprise has been developed, which, unlike others, has two tree-like topologies connected at the initial nodes by a wireless network, which allows to equip two physically separate blocks of the enterprise, without the need to install Internet wires in private premises. In the course of the study, based on analytical calculations, a network model was built in Cisco Packet Tracer, a pool of static addresses required to connect local devices was determined, and an algorithm for further network installation was formed.
