Open service architecture for heterogeneous home environment

Appliances are essential elements of all modern homes. We give an overview of a home network service architecture. It aims to define a home network system that offers desired services and privacy for end-users, and in which networked appliances can be controlled remotely. The architecture is component based. It does not impose constraints on the physical position of the software components - it leaves all possibilities open, depending on the scale of the home system. Additionally, the architecture is independent of physical media, so it supports wired and wireless communication. The business roles are introduced and a trial using extended SIP for remote controlling appliances across the Internet is briefly discussed.
