Introduction. Wireless sensor networks are increasingly penetrating every year in all industries and fields of activity. Currently, they are widely used not only for data collection and processing and management of industrial sites but also in normal life as Internet of Things [1]. Wireless sensor network has ceased to be the only object of research and becomes a mass product that is produced by many manufacturers.Existing and projected wireless sensor networks are different as areas of application, as technical solutions used to [2]. Nonetheless, it is identify the main characteristics that are typical of most wireless systems. Typical wireless sensor network consists of a large number of simple devices or nodes to gather information, some more complex devices -coordinators for information processing and network control and data channels. Each node performs periodic measurements, primary processing of information and transfer these data to the coordinator. In the coordinate data is processed and stored, and if necessary, transferred to a higher level or to another system. Nodes can transmit measured information not only directly to the coordinator but, if necessary, through other intermediate nodes. Typical scenarios of using wireless sensor networks impose certain restrictions on the structure and operation of the nodes. In particular, the nodes should be smallsized, cheap enough and have a very long battery life. Consequently, the nodes have energy and computational limitations that should be considered by the designing networks. Coordinators perform functions other than nodes and, for this reason, often have more powerful processors, more memory and better sources of independent power. It should be noted, that the specific network provides data transmission from the node to the coordinator through one or more intermediate nodes. At the same time, there are important technical condition monitoring and timely recovery of individual sensor network nodes.
