The fundamental possibility of determining the location of nodes of the sensor networks in space (positioning of sensors) makes these systems even more attractive due to the additional information component, which, together with the main parameter or a set of monitoring parameters, can give an exhaustive picture of the system's operation. The tasks of positioning during the construction and operation of a wireless sensor network are one of the most important, both in regard with the need to build the sensor network itself and to ensure rational routing during its operation. Due to the fact that a wireless sensor network is usually a cluster structure, it is necessary to determine the location of the head node for the cluster as accurately as possible during its formation. The paper proposes methods for positioning nodes of the wireless sensor network are proposed, taking into account the possibility of measuring the parameters of the received signal. The method of positioning of nodes on the basis of bind points is proposed. Estimation of errors of the positioning of nodes in the wireless sensor network is carried out. Анотація-Завдання позиціонування при побудові та функціонуванні безпроводової сенсорної мережі є одними з найважливіших як у зв'язку з необхідністю побудови самої сенсорної мережі, так і для забезпечення раціональної маршрутизації при її функціонуванні. У зв'язку з тим, що безпроводова сенсорна мережа являє собою, як правило, кластерну структуру, необхідно як можна більш точне визначення місця розташування головного вузла для кластера при його формуванні. В роботі запропоновані методи позиціонування вузлів безпроводової сенсорної мережі з урахуванням можливості вимірювання параметрів прийнятого сигналу. Запропоновано метод позиціонування вузлів на основі точок прив'язки. Проведено оцінку помилок позиціонування вузлів у безпроводовій сенсорній мережі.

A method of managing a wireless sensor network of optical-electronic stations (OES) using LoRa technology is developed. Within the framework of the system of optic-electronic stations, two subnets are functioning: the video stream transmission network and the control network, which is the subject of this work. The main requirements for the control network were the following: the ability to ensure performance in radio-electronic suppression conditions, the provision of high-range radio communication, the ability to operate in conditions of dense urban development, the network energy efficiency, and the high stealth level. Technologies available on the market for building sensor networks were analyzed. LoRa technology was chosen for these purposes considering the established requirements for the network. The current network layout was created based on EBYTE E32-433T20DT LoRa radio modules. The basis of the developed method is two classes of commands for configuring the network of optical-electronic stations. The first class of commands is network management commands, operations to add and remove devices from the general routing table. The second class of commands controls communication modules and microcontrollers, changing their configuration parameters. The OES network’s control algorithms were developed based on these commands. Created commands and algorithms helped significantly facilitate and speed up the operator’s initialization and network configuration process and are already used in the current layout of the optical-electronic station system.
