Architecture of Home Gateway for Device Collaboration in Extended Home Space

Extended Home Space refers not only to home appliances but also to logical space, including a wide range of out-home personal devices such as mobile phones, PDAs, laptops, car navigators, and office PCs. Seamless networking and collaboration among these devices is essential to provide users with a ubiquitous home environment in which they call use home services whenever and wherever the v want to. In reality, however, there are certain barriers to this, such as the dynamic IP address, NAT and heterogeneous service protocols. fit this paper, we propose a Home Gateway that provides unrestricted collaboration between personal devices in the extended home space by overcoming these barriers with P2P networking technology
