On the Fly Proxy Generation for Home Devices Interoperability

Different plug and play protocols coexist in home networks and each protocol defines its own profiles, data semantics and networking layers, thus interoperability between different devices cannot be applied. We take advantage of the device description annunciation to automatically generate ontologies representing the device, then we apply semi automatic alignment heuristics to find correspondences between equivalent entities. Once the alignment is validated and updated by a human, it is used with predefined code templates to automatically generate software modules "proxies" to hide the device heterogeneity. We validated our approach on a real DPWS printer.
