In the smart home environment designed for many users, not only a single context, but also multi-context simultaneously exists, which continues to generate and perish with the passage of time. Therefore, this paper has designed a Service Oriented Architecture based MVC and composed a smart home scenario on the basis of the Enneagram principle, which can aware of conflict resolution between the RRC(Resource, Role, Context) and also which is able to respond effectively according to the scope of domain.
The Enneagram, which provides a theoretical idea for designing the Service Oriented Architecture demanded under a smart home context, is able to provide an excellent prototype that well describes the relationship between the entirety and rotational process of an event. It is described in the Monad(0), Triad(9-3-6), and Heptad(7-1-4-2-8-5-7). These make contribution to the whole event, and Enneagram organizes these principles into a diagram. The Service Oriented Architecture suggested in this paper has been designed by taking into consideration the UPnP, OSGi, and SOA Tool Platform for eclipse platform. A service provider manages related kinds of services on an integrative basis from various sensors, puts each service in a WSDL/SOAP message, and registers them to the UDDI server of service mediator. Under the environment of an OSGi service platform, various context-aware services are dynamically being mapped from various sensors and bundled services are available.
By applying the modified ATAM, which is the service evaluation methodology for scenario-based architecture, this paper has made a utility tree from a business objective, designed the scenario for system quality, and thus providing a systematic approach to quality element. Therefore, if transaction throughput is 546 TPS and system availability is 98% and resuability COTS is 35%, then service requester satisfaction is 85.1% in maximum value set, so and if data latency is 2000 ms and system reliability is 1 Min and modify COTS is 1 Man/Day , then service requester satisfaction is 70.1% in minimun value set from ATAM while remaining stable other condition. Also this paper provides a useful idea for plug-in architecture modeling and for an eclipse-based OHP, which has adopted the HL7 and IHE standard by domain size or by stakeholder in the U-Healthcare field. existing services are changing new services are being offered for the asking of users
