Abstract
The architecture of a conventional smart home system is usually server-centric and thus causes many problems, and it is also not suitable for ubiquitous computing environment. Applying a traditional server-centric architecture in a ubiquitous computing environment, the dynamically changing environment, which is caused by mobile devices and dynamic services, can result in very difficult interaction, and also makes system resources not fully utilized. In addition, how to provide services efficiently and appropriately is always an important issue for a smart home. To solve the problems caused by traditional architectures, to deal with the dynamic environment, and to provide appropriate service, in this thesis, a service-oriented architecture for smart home systems is proposed based on OSGi and mobile agent technology. This architecture is a Peer-to-Peer model based on multiple OSGi platforms, in which service-oriented mechanisms are used for system components to interact with one another, and mobile agent technology is applied to augment the interaction mechanisms and to fully utilize system resources. And when designing system components in this proposed architecture, the concepts of context-aware, mixed-initiative, and intelligent machine are applied, for smart home systems to provide appropriate services, to possess suitable human-computer interaction mechanism, and to achieve dynamic and efficient intelligent control. Based on this proposed architecture, current smart home is a ubiquitous computing environment consisting of multiple agent-based autonomous spaces, and its advantage is that a service interacting with home users can be set with different configurations in space, hardware, software, and quality. Not only being smart technologically speaking, a smart home should also never forget to retain the “home nature,” including warmth and/or relaxation, when it is serving its users. Therefore, from the viewpoint of human-computer interaction, the relationship among services, spaces, and users, is analyzed. And based on this analysis, a framework and its corresponding algorithm to model their interaction are proposed, so that a smart home can behave like a smart system while maintaining all kinds of “home” functions.
