Abstract
Based on the idea of Service Oriented Architectures (SOA), Web Services paved the way for open and °exible interac- tion between heterogeneous systems with a loose coupling between service endpoints. The Device Pro¯le for Web Ser- vices (DPWS) implements a subset of WS-* speci¯cations in order to make the advantages of the Web Service archi- tecture available to a growing embedded systems market. In this paper we are proposing a service orchestration mecha- nism applied to services on top of a DPWS-based middle- ware. The approach is complementary to the rather complex and resource intensive Web Service Business Process Execu- tion Language (WS-BPEL) and focuses on service orchestra- tion on resource constrained devices deployed in hierarchi- cal network topologies. We validate our service orchestra- tion concept through its resource consumption and illustrate its seamless integration into the service development cycle based on the underlying DPWS-compliant middleware.
