An approach to efficient collaboration of embedded devices with different functions

Embedded devices which can connect to the Internet and communicate with other devices have been increased. However, most of them are totally-optimized for their specified purposes and have only limited processing capability and specialized I/O devices. In this paper, an efficient collaboration scheme for embedded devices is proposed. Communicating with other devices and utilizing their functions can create much more convenient services. We adopt CC/PP and WS-BPEL for the proposed system. CC/PP is an XML language for describing device capabilities and user preferences, which is being standardized by W3C. WS-BPEL is an XML-based programming language standardized by OASIS. In order to consider the feasibility of the proposed system, a prototype system was constructed, which is composed of a graphical authoring environment for collaboration programs and an emulation environment for confirmation. Examining a use case for collaboration between a television and a cellular phone, it was confirmed that our proposed system works as required.
