Accidents at critical infrastructure facilities are accompanied by damage to regular data transmission networks from sensors monitoring critical parameters of technological equipment to crisis centres. The absence of such data can lead to erroneous and insufficiently informed decisions by the crisis centre staff during actions to localise and eliminate the consequences of the accident. As an alternative to damaged regular networks, a LiFi network based on unmanned aerial vehicles (UAVs) can be considered, where the latter act as repeaters. However, due to the destruction of equipment and structures in production facilities, mechanical interference may occur, which will require the construction of LiFi signal propagation routes to bypass these obstacles. The subject of the article is the means of planning the deployment of flying networks to ensure data transmission in the conditions of destruction. The purpose of the article is to propose a software tool to support the planning of UAV-based LiFi network deployment to ensure data transmission in the conditions of destruction of critical infrastructure facilities. Objectives of the article: to propose a scheme for deploying a UAV-based LiFi network in a production facility with obstacles; to present the architecture and features of the software tool for implementing the proposed scheme; to provide examples of using the software tool. The following results were obtained. A software tool has been developed to support the planning of the deployment of a UAV-based LiFi network in industrial premises with obstacles, which allows you to lay routes for the propagation of LiFi signal (light flux with data) and determine the required number of UAVs and their location on the route. The results of applying a software tool for planning the deployment of a LiFi network in a given production facility with obstacles using the rectangle and controlled waterfall methods to bypass them and build routes are presented. The direction of further research is to develop a method and software tool for determining the required number of shifts and the number of UAVs in each of them to ensure the uninterrupted operation of the LiFi network formed by them for a given time with the customer-defined probability of the failure-free operation.Downloads
