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.
