Smart home architecture based on event-driven DPWS～+

摘要

With the advances of electronic information technology and computer network,especially the embedded technology,smart home is no more just a vision but being practical.The interoperability of heterogeneous devices and flexibility of devices' usage are two key problems that challenge the implementation of smart home.To deal with these two issues,this paper proposes an event-driven service oriented architecture using device profile for web services(DPWS).DPWS inherits the advantages of the traditional web services in achieving interoperability without dependence on platform,while improving service discovery and security as well as being optimized for deploying on resource constrained devices.By providing a visual interface for describing a service workflow(SW),the user can easily customize the actions of devices by services composition.Devices automatically cooperate without user's intervention to complete required business logic.This is achieved by fully exploiting the eventing capabilities on DPWS enabled home devices.Finally,a home theater scenario is given to illustrate the event driven mechanism for the SW in the proposed smart home framework.
