Context-Aware Gateway for Ubiquitous SIP-Based Services in Smart Homes

The smart home concept brings innovation and convenience to our every day´s life style at home. Without context awareness, smart home applications cannot offer services that can adapt to users?? dynamic situations; they also fail to give preferential treatment for users?? various preferences. Such design paradigm forces human to live in the world of machines rather than a human oriented world. The use of SIP-protocol allows Smart Home devices and services to be connected compatibly and effectively. In this paper, we propose an adaptive SIP Context-Aware Gateway (SCAG) for the ubiquitous SIP-based services. With the SCAG solution, the home owner is able to use preferred devices for communication and to post his/her context information to home appliances or to people and civil society communities on an ??as needed?? basis.
