Electrical load control systems based on wireless data networks with self-organizing topology

The article provides an overview of modern wireless communication protocols used in residential automation systems to solve the problem of powerful household electric loads remote switching. A comparative description of the existing wireless communication protocols is provided. The existing components range is analysed for availability and the possibility of their application in the commercially available control systems. The review of modern wireless technologies serves as a basis to select the technology of self-organizing networks with ESP-MESH mesh topology to set up the remote control of electrical loads in residential building automation systems. The authors consider its advantages, including the most important one, i.e. the IP addressing, and the resulting high integration with such widespread network technologies like Wi-Fi and Ethernet, which is relevant for this application. The proposed option allows for the design of the automation systems for residential buildings to solve the problems of ensuring communication reliability by means of the network topology self-organization, covering the zones, the dimensions of which exceed the communication range of traditional point-to-point systems. At the same time they ensure the security of data transfer due to the data provided by the developers of the ESP-protocol MESH and encryption technology. In this case, the dependence of the probability and conditional probability of establishing a connection on the number of closed transits (disconnection between network nodes) was considered.
