Wireless Network Technologies for Smart Homes
A Technical and Economic Analysis
Keywords:Economical and Technical Analyze, IoT, Smart Grid, Smart Home, Wireless Technologies
The Smart Grid concept is being implemented and it is a close reality, its application has been accelerated by the reduction of the electronic component’s costs, the Internet of Things evolution and the necessity to develop more efficient solutions for electric vehicles and distributed generation. The main projects around the world are starting with the implementation of Smart Homes, due to the greater easy technical solution and high compensation. These implementations are accompanied by technical and economic barriers, due to the increase in data generation and the increase products price. One of the problems reported is the large variety of technologies communication and the lack of interoperability between the manufacturers' solution. This document focuses on the study of the main wireless networks, Sub-GHz, Wi-Fi, and ZigBee, making a comparison through technical and economic analysis of the networks. The technologies are tested by means of a computational experiment, parameterized by data obtained from a field test, applied in a real environment, based on a residence in Brazil. The simulation was used to evaluate wireless network technologies more broadly, allowing to simulate a complete Smart Home environment for energy and demand management, applying a communication node for each energy point. The economic analysis relates the direct cost of technology module and their energy consumption, based on rates from the local distributor of the residence. In conclusion, the Wi-Fi wireless network, based on the IEEE 802.11 standard, is the best solution for demand and energy management applications in Smart Home environments, with higher transmission success rates and better cost benefit.
