Ambient assisted living devices interoperability based on OSGi and the X73 standard

The need for interoperability among devices is an issue of vital importance in current telemedicine systems. Although a completely standardized system is an ideal solution, most commercially available devices include their own software and communication protocols, which cause serious problems and hinder the application of a standard. Patients' telemonitoring at home requires a wide variety of biometric and ambient sensors and devices that usually present a set of very specific features and characteristics. The present article introduces a system based on the Open Services Gateway Initiative architecture, which offers plug-and-play connectivity of ambient assisted living devices. Using a data model inspired by the X73 standard, we describe a set of bundles that reduces the interoperability problem and allows the data stored in the platform to be independent from the connected devices.
