Design and Implementation of Scenario-Based Collaborative Framework: XCREAM

The XCREAM (XLogic Collaborative RFID/USN-Enabled Adaptive Middleware), as a mediator between smart physical objects and collaborative cyber services, gathers massive events from a variety of event origins and distributes them to the appropriate service parties depending on the predefined business scenarios. Demand for collaboration among numerous business applications draws attention to this kind of middleware platform especially in the highly networked environment. The XCREAM platform, the scenario-based collaborative framework, integrates various kinds of RFID/USN enabled application services and provides more advanced services than the individual services. The goal of this research is to construct well-organized systematic RFID/USN prototyping framework, to which physical RFID readers or sensor devices are directly connected. Additionally, tag data and sensor signals from the devices are propagated to the proper services registered to the framework. The study encourages us to develop the XCREAM platform and build prototyping environment for presenting further comprehensive services. This approach makes it possible to integrate many heterogeneous services and to present collaborative service framework.
