Hierarchical Framework for Implementation of Intelligent Space

In this paper, the problem of implementation of Intelligent Space (iSpace) is considered. iSpace is a room or area where many intelligent sensors and actuators are distributed and networked. In iSpace, the embedded sensors can monitor the whole environment by communicating with each other through the network. Based on the observed information, the actuators provide informative and physical services to users. Such a system should have flexibility and scalability so that we can easily change the configuration of embedded devices and switch applications depending on the situation. It is also important for the system to have a function that fuses the information acquired by each sensor and share it with other devices efficiently. We present a basic framework of Intelligent Space and show the current configuration developed in our laboratory. Some experimental results are also shown.
