The Amigo interoperable middleware aims at enabling ambient intelligence within the networked home environment by addressing the seamless integration of networked devices and related application services within the home system (ie, devices from the Consumer Electronics (CE), home automation, mobile and PC domains). The Amigo interoperable middleware architecture is specifically designed to realize an open networked home system that dynamically integrates heterogeneous devices as they join the network (§ 2). Our demonstrator (§ 3) will show interoperability among heterogeneous networked services from the CE, home automation, mobile and PC domains, using the Amigo middleware (§ 4).
