Flexible Discovery of Components for Sensor Data Processing by RDF in Network Middleware for Home Environment

摘要

This paper discusses the discovery mechanism of program components based on knowledge descriptions of home sensors in network middleware. Descriptions are written in Resource Description Framework (RDF). RDF descriptions are easily appended to new information and connected to other knowledge. Developers and programs search appropriate program components based on knowledge such as sensor properties in the middleware. We prepared knowledge on sensor-embedded objects and constructed program components for an occupant's location estimation and a context-aware application. Experiments show the feasibility of flexible discovery for heterogeneous program components using RDF-based description.
