Interface Matching and Combining Techniques for Services Integration

The development of many highly dynamic environments, like pervasive environments, introduces the possibility to use geographically close-related services. Dynamically integrating and unintegrating these services in running applications is a key challenge for this use. In this article, we classify service integration issues according to interfaces exported by services and internal combining techniques. We also propose a contextual integration service, IntegServ, and an interface, Integrable, for developing services.
