Currently the research and development of various types of middleware for the ubiquitous computing environment are in demand, and many application services are therefore being provided. The practical ubiquitous computing environment is world in which a variety of services based on RFID/USN devices are integrated, creating synergy effects. From perspective of the end user, there should be a middleware platform and a business logic framework that join various services together to satisfy a range of user requirements. In addition, the platform should provide the user with a description of a scenario based on various events to maximize the collaboration. In this paper, we propose a business logic framework that supports collaboration between heterogeneous service systems based on user scenarios. We also attempt to show the efficiency and scalability of the proposed framework by providing the result of several tests.

Keywords: ubiquitous computing environment, middleware platform, business logic framework, scenario-based, RFID/USN
