DEVELOPMENT OF A WIRELESS CONTROL SYSTEM ON THE BASIS OF «THE INTERNET OF THINGS» CONCEPT
A.I. Afanasiev, V.N. Knyazev
In the article it is discussed current issues and problems of developing wireless control systems based on the concept of «Internet of Things». As important problems here there are an insufficient flexibility and efficiency of the choice of communication channels for data transmission, the insufficient protection of communication channels and the ways to solve these problems were proposed. The scientific novelty is in the development of an adaptive algorithm for selecting a channel for data transmission, which is different from the well-known algorithms by higher flexibility and reliability. The flexibility (adaptability) of the algorithm is the automatic identification of available channels, and the reliability is providing of guaranteed transfer of the control commands. Also there were proposed a modified encryption algorithm based on the combined using of a symmetric encryption algorithm GOST 34.12-2015 and an asymmetric encryption algorithm on elliptic curves, allowing to increase the level of reliability of the protected interaction between the components of the control system while ensuring a sufficient speed of message transmission. There was designed a wireless control system with using an ontological and visual modelling among other things. The results, which were received in the course of the study were used as the basis for creating hardware and software of an automated control system for «IoT» devices for a private house.
