Service composition architecture for programmability and flexibility in ubiquitous communication networks

This paper addresses a new service composition method suitable for the forthcoming ubiquitous computing era. The latest developments in network computer technology have made various entities connected to the Internet, such as Web services, sensors, and home information appliances, accessible to those who want to create their own service capabilities. The architecture we have thus far proposed is a key to achieving the ubiquitous concept, but approaches that spread the use of the architecture are required. We establish the architecture more widely usable in mobile Internet environments and suggest applicable domains for two types of proxy servers to compensate for the shortage of mobile terminal capacities. Practical service examples and business models are also discussed.
