Discovery and On-demand Provisioning of Real-World Web Services

The increasing usage of smart embedded devices is blurring the line between the virtual and real worlds. This creates new opportunities for applications to better integrate the real-world, providing services that are more diverse, highly dynamic and efficient. Service Oriented Architecture is on the verge of extending its applicability from the standard, corporate IT domain to the real-world devices. In such infrastructures, composed of a large number of resource-limited devices, the discovery of services and on demand provisioning of missing functionality is a challenge. This work proposes a process, its architecture and an implementation that enables developers and process designers to dynamically discover, use, and create running instances of real-world services in composite applications.
