Network infrastructure development for the «Smart Home» system using Z­-Wave technology

Ready-made solutions for building the network infrastructure of the «Smart Home» system are analyzed, their advantages and disadvantages are revealed. The article discusses in detail the use of Z-Wave technology in building a network for «Smart Home». The plan of building a new network infrastructure is formulated. Based on the analysis, a network infrastructure was developed for the Smart Home system using Z-Wave technology. Z-Wave was introduced to the market in 2003 by Zensys, acquired five years later by Sigma Designs, which now licenses the technology and remains a major supplier of Z-Wave chips. Addressing all the critical needs of the emerging smart home segment, it has become a leading international wireless standard for residential automation management and automation. To date, there are more than 1300 certified devices on the market and around 35 million compatible units are mature and proven technology. Simple Z-Wave covers all layers of the core OSI model for network communications, from the physical layer to the application layer. Unlike the vast majority of the leading wireless solutions, the protocol provides full compatibility between the various branded products based on it. This would be impossible without determining the level of applications, but also without the clear standard and certification programs installed by Z-Wave Alliance. Z-Wave was designed to allow individual nodes to send messages until they reach their final destination. Extending the range of the wireless network significantly, even today, networks are considered essential to providing reliable coverage in building automation. First of all, the Z-Wave network is capable of sending messages through up to 4 repetitive nodes. This alone limits potential applications in a smart home environment, as commercial and office space often require wider network coverage.
