Smart home networking: Combining wireless and powerline networking

Integrating the power grid technology with renewable power generation technologies, Demand Response (DR) programs enabled by Advanced Metering Infrastructure (AMI) were introduced into the power grid in the interest of both utilities and residents. They help to achieve load balance and increase the grid reliability by encouraging residents to reduce their power usage during peak load periods. We compare mainstream network technologies applicable to home appliance control and propose a solution combining Power Line Communication (PLC) with wireless communication in smart homes for the purpose of energy saving. Moreover, we explore and evaluate the network performance of DR programs in smart homes in such a combined network via a simplified networking simulation model.
