Healthcare Home Service System Based on Distributed Object Group Framework

This paper suggests a healthcare home service system based on the Distributed Object Group Framework (DOGF) for ubiquitous healthcare in home environment. This system consists of 3 layers. The lower layer includes the physical sensors and devices for healthcare, as a physical layer. The middle layer is the DOGF layer. This framework supports the object grouping service and the real-time service to execute the healthcare application. Here, object group means the unit of logical grouped objects or healthcare sensors/devices for a healthcare service. We define these grouped objects as an application group, also sensors/devices as a sensor group. And this layer includes interfaces between application group at the upper layer and sensor group at the physical layer. The upper layer implements healthcare applications based on lower layers. With healthcare applications, we implemented the location tracking service, the health information service, and the titrating environment service. Our system can provide healthcare application services using the healthcare information from the physical healthcare sensors/devices, and also can be monitored and controlled the execution results of these services via remote desktops or PDAs.
