Studies of the leading trends in the development of telecommunications show that networks are the basis for building any communication system. The document discusses the problem of providing control of various IoT devices, the diagrams of which are functional elements of a single hierarchical model based on a wireless sensor network. A feature of the hierarchical model is the use of the same type of elements at different levels of the hierarchy. The article presents a technique for constructing a mesh-network, based on the complex application of modern element base, software components and an interface for preparing the system for operation, its use and data analysis. The presented model and its practical implementation can be used as a basis for the IoT laboratory and other applications.

Hierarchical Model OF A Complex of IoT Devices Based on the Use of a Wireless Sensor Network

This work considers a method to ensure the security of a small corporate network on the first line using the OpenDNS cloud service. Using the Internet every day, you expose yourself and your computer to risk. You may run into certain threats that harm your computer or run into content that contains obscene content.
