9.Summary of Research Results
This project aimed to develop innovative network architecture for supporting future Internet applications. The key concept of the project was utilizing location-independent naming technology so that we can access various services transparently and flexibly on the Internet.
At the first step of the project we have designed a naming-based service composition system called STONE (Service Synthesizer on the Net). Our system is built on the top of the Internet architecture, and has capabilities of seamless locating and synthesizing of various services. In our design, we utilize interface information to locate various objects. Interface information enables us to design scalable name management and name resolution algorithms in a fully distributed manner. In addition, interface information not only enables the transparent location of functional objects, but also enables the naming system to support service synthesis.
To support the STONE system, we have also developed various protocols such as session layer mobility support protocols and collaborative session management protocols. In addition, we designed and implemented real-world information processing system such as a wireless sensor network system "U-Cube" and a distributed ultrasonic positioning system "DOLPHIN". These systems were developed to enrich applications of the STONE system based on real-world information.
Finally we constructed a testbed called "STONE Room" to show the advantage of our architecture. We installed prototype of above mentioned systems to the testbed, and developed various applications.
