Abstract

<jats:p>Применение беспилотных объектов для мониторинга территорий, удаленных от центра управления, требует решения вопросов организации надежной связи между источником информации и оператором. При этом главная задача заключается в обеспечении живучести и дальности каналов в условиях действия радиопомех. Проблема особенно актуальна в случае использования множества («роя») БПЛА, работа между которыми должна быть координирована. Решить эту задачу можно с помощью технологии MESH, в основе которой лежит принцип ретрансляции информации от одного узла к другому. Эффективным способом борьбы с преднамеренными помехами может быть метод псевдослучайного изменения несущих частот в MESH-сети. Главное – это поиск оптимального соотношения между количеством узлов БПЛА и числом несущих частот, которое определяет доступность сети.</jats:p> <jats:p>The use of unmanned objects to create monitoring systems for areas remote from the control center requires solving the issues of organizing reliable communication for data exchange between the source of information and the operator. The main issues are ensuring the necessary survivability and range of channels in the presence of radio interference. This task is especially relevant when using a swarm of UAVs, which must be coordinated with each other. This task can be solved using MESH technology. The advantage of MESH technology is the principle of relaying information from one node to another. This allows for the expansion of the monitoring area by adding additional UAVs, and also increases the network’s survivability in the event of a physical loss of an UAV or communication disruption between nodes due to interference. An effective way to combat intentional interference is to use a pseudo-random method of changing the carrier frequencies in the MESH network. To improve the availability of channels, it is necessary to calculate the optimal ratio between the number of nodes (UAVs) and the number of carriers used in the MESH network. The maximum allowable distance between the nodes of the MESH network is also an important consideration. This can be achieved by determining the optimal density of UAVs in the monitoring area. Hybrid 5G NTN networks, which combine the principles of cellular and satellite communication, can provide the maximum distance between the MESH network and the monitoring control center. The use of modern MESH technologies and hybrid 5G NTN networks to organize UAV control channels in remote monitoring systems will allow for the coverage of the Arctic zones and territories of the Far East.</jats:p>
