The comfort system based-on agent framework and smart lighting controlling application

— In the area of distributed systems, there is a segment gaining more importance due to recent development in hardware and software technology. This is the area of home networking. Its target is making inhabitants get more and more comfortable. Comfort system may be considered as value-added services. They can be: the remote access and automatic control of appliances, the surveillance of the house or alarming the house owner if something unexpected happens, the multimedia services e.g. video on demand and the health care. This paper presents a comfort system agent-based framework used in home automation. In our system, a service for a person is embodied by a mobile agent. When the person enters a room, his assistant agent will be sent to the corresponding context in the agent framework. At that context, this assistant agent encounters and interacts with other agents. The system provides a mechanism that follows to develop services where assistant agents can coordinate to reach an acceptable comfort level. In particular, we have constructed a smart lighting controlling service that manages and controls the light in the house. Suppose that one room may have many lighting sources, and one person has preferences and desires about lighting sources and intensity according to his humor. With this service, assistant agents coordinate and select automatically the preferred lighting sources and intensity.
