The XCREAM Framework and Collaboration Validity Tests

The purpose of the XCREAM (XLogic Collaborative RFID/USN-Enabled Adaptive Middleware) is to enable collaboration among many RFID/USN-enabled applications by providing them with flexible interface to the XCREAM through a web-based service scheme, called the Enterprise Manager, and XML infrastructure language, the XLogic script language. Rapidly growing demand for collaboration among numerous and heterogeneous business applications draws attention to this kind of framework, especially in the ubiquitous computing environment. The XCREAM framework gathers massive events from a variety of event sources and distributes them to the appropriate service parties depending on the predefined business scenarios. The scenarios are written in the XLogic script language and registered to the XCREAM framework. The paper includes simulation result which shows excellence in performance and validity of collaboration support of the XCREAM. Reviewing the test results, XCREAM works well, especially in the collaborative environment. This approach makes it possible to integrate many heterogeneous services with various data sources and to present a collaborative service framework.
