SeDeUse: A Model for Service-Oriented Computing in Dynamic Environments

The current state-of-the-art in service-oriented computing targets mostly business-to-business interaction, as service directories store business specific instead of general, abstract, interfaces. Moreover, the established coordination models were designed to operate mainly over business processes with immutable, previously known, locations and tightly couple resource awareness and usage, inhibiting the programmer to separate the purpose of the program from its execution environment. In this paper we present SeDeUSe, a model that features novel programming abstractions sustained by a middleware layer that hides the idiosyncrasies of using service-oriented computing in highly dynamic environments.
