Summary & Outlook
eHome model supports the specification, configuration, and deployment of eHome services
Outlook» Dynamic reconfiguration based on more aspects than only
required functionalities, e.g. QoS» Composition verification, e.g. by parametric contracts» Migration of service functionality (support of multiple
environments)• Separation of user profiles from context information• Detection and resolution of service interaction conflicts• Privacy & security
