This book analyzes the Home Automation System and the evironmental problematics within, facing the problems that characterize it and limit the development of the Smart Home in the framework of the Smart grid programme, defined and currently developed in Europe and United States. The approached thematics have been described distinguish them in two macro-areas: the study and the analysis of the communication protocols to endow the house with a network infrastructure needed to provide all the requests relative to the Home Automation. The latter was focused on the control logic and coordination of the various devices that composes a typical household scenario. Two methods (named GT-HAS and MKP-HAS) have been developed, tested and validated for resolving conflicts which can occur when the devices are trying to use shared resources in a typical household installation like electricity and hot water. The Analysis of the two algorithms highlights the weaks and the strong points of both the developed methods in several scenarios.
