| Summary: | The number of service techniques available for digitized home appliances is rapidly increasing as a result of various advances in digital technology. Users can now easily control and monitor home appliances via sensor networks formed among home appliances in ubiquitous environments. However, home appliances generate such large amounts of metadata about their status every month that in order to provide home appliance monitoring services to users, an approach that is able to store, analyze, and process these large amounts of metadata is needed. We propose a system that uses UPnP to collect metadata from home appliances and cloud computing technology to store and process the metadata collected from ubiquitous sensor network environments. Our proposed system utilizes a home gateway and is designed and implemented using UPnP technology to search for and collect device features and service information. It also provides a function for transmitting the metadata from the home appliances to a cloud-based data server that uses Hadoop-based technology to store and process the metadata collected by a home appliance monitoring service.
