The OSGi (open service gateway initiative) service platform specification is the most widely adopted technology for building a control system for the networked home. Three main features contribute to its success. First, it supports various well-known protocols, simplifying communication among home devices. In addition, it defines a cooperative model for applications to dynamically discover and use services provided by others. Finally, it allows flexible remote management of these applications and the services they provide. So, an OSGi solution supports decentralization, diversification, and ubiquity not only in smart homes but in pervasive environments generally.
