A Middleware Platform Based on Multi-Agents for u-Healthcare Services with Sensor Networks

The XCREAM Framework and Collaboration Validity Tests

“…As various kinds of ubiquitous computing applications, such as u-Healthcare, u-Transportation, u-911, and u-Eco, are rapidly introduced to our day to day life, it is expected that the increase of the information sharing from variable RFID/USN data sources will stimulate the development of the composite services [8]- [10]. Several middleware researches are having conducted on the following examples: MiLAN middleware [7], developed to guarantee QoS (Quality of Service) as its top priority; event-based DSWare middleware [11], which sends desired data to USN application systems by setting events on continuous stream of sensor data obtained, similar to RFID middleware; Impala middleware [11], [12], which can dynamically change functions of sensor node middleware according to changes in USN application services and changes in the surrounding environment of sensor networks through wireless communication; TinyDB middleware [14];…”
