Low voltage electrical wiring has been ruled out because it is too loud and unpredictable to support high speed communication signals. Advances in communication and modulation methodologies, as well as in the adaptive processing of digital signals and the detection and correction of errors, have generated new protocols capable of supporting communication networks of power lines at speeds comparable to wired LANs. Through simulation and real-time measurements using prototypes of commercial powerline products of "reference design", we demonstrate that HomePlug MAC and PHY layers can guarantee QoS for real-time communications, admitting delay-sensitive data flows for smart home applications .
Wireless sensor networks (WSN) and power line communications (PLC) are used in this work to implement a smart home control network. The objectives are to reduce the impact of wireless interference on a smart home control network and the unnecessary energy consumption of a smart home. An isolated WSN is established with a coordinator, which is integrated in the PLC transceiver, in each room. The coordinator is responsible for transferring the environmental parameters obtained by WSNs to the administration station through PLC. Control messages for household appliances are transferred directly via PLC instead of WSN. According to the experimental results, the impact of wireless interference on the proposed smart home control network is mitigated substantially. In addition, an intelligent control algorithm for lighting systems and an analysis of the illumination of a fluorescent lamp was presented. The energy saving of the lighting systems was evaluated in relation to those without intelligent control. The numerical results indicate that electricity consumption on a sunny or cloudy day can be reduced by at least 40% under intelligent control. In addition, a prototype was implemented for the intelligent home control network proposed with the intelligent control algorithm. Experimental evidence shows that the proposed system for smart home control networks is practically feasible and works well.
