Design of RFID-Based Profiling Agent for Recommendation System in Smart Home

Research on ubiquitous environment has been being conducted actively until now. In particular, a user positioning system provides user location data, which is the most important context information in applications based on context information. Despite their many advantages, existing applications, which do not consider elements related to real-time data communication among remote RFID devices, cannot support connections among heterogeneous devices effectively. As different network devices are installed in applications separately and go through different query analysis processes, there happen the delays of monitoring or errors in data conversion. A personalized profile is composed of collector that contains the characteristics of the profile, aggregator that collects profile data from various collectors, and Resolver that interprets profile collectors specific to profile characteristic include contextual information. The personalized module helps the service recommendation server make regular synchronization with the personalized profile. The proposed system can easily extend the matching of services to user profiles and matching between user profiles or between services.
