Service discovery in a DOM-based middleware architecture

Heterogeneity and uncertainty are two main characteristics of pervasive computing environment and CSCW. CSCW can be viewed as a special case of pervasive computing. Middleware is a good approach to accommodate heterogeneous and dynamically changing devices for CSCW and pervasive computing. In this paper, we propose the service discovery method adopted in our DOM-based middleware architecture, which aims to support as many types of pervasive environments as possible. Services in our middleware architecture are dynamically structured and can be adapted to the environments´ changes or users´ requirements. Our middleware architecture can also be used to support service collaboration in CSCW.
