Design of Scenario-Based Architecture for Supporting Interoperability among Heterogeneous Home Network Middlewares

First investigate an integrated architecture for supporting interoperability among heterogeneous middle wares under home network. We then propose a scenario-based user-oriented integrated architecture for efficient home automation. HOMI(Home network Middleware for Interoperability) architecture proposed in this dissertation provides interfaces that assist users with designing and modifying desirable scenarios using a script language called HOMIL(HOMI Language). Different from existing integrated middleware architectures, HOMI improves efficiency and convenience of interoperation between heterogeneous appliances for home automation allowing users to construct and organize scenarios through these interfaces. HOMI classifies interoperation services into time context, synchronization context, and a synchronization context and helps to execute next services considering contexts when a specific event occurs. Applying modified scenarios immediately to home network environment, HOMI assists users with receiving seamless services without installing new applications, updating the server, or rebooting in order to adapt new scenarios. Lastly, distributing agents into multiple devices, we reduce the overhead occurred in a centralized the integrated middleware architecture.
