Service-Oriented Middleware for the Cooperation of Smart Objects and Web Services
- 4.2k Downloads
Many physical devices can be interconnected and cooperate by Internet of Things (IoT), providing and consuming information available on the network. These will not only provide information by monitoring the real-world, but create complex collaborations, interacting also with business processes, in order to provide sophisticated value-added services. In addition, business processes can also adapt their behavior in response to real-time context updates. Web services technology offers a promising approach to provide information and functionalities of physical objects to business processes, since it facilitates interoperability and encapsulates the heterogeneity and specificity of physical objects. To address the dynamic composition of web services in a decentralized, distributed manner, with no single point of failure, a choreography execution model can be used. This chapter describes an approach to support adaptable business processes (workflows) considering changes in the state of Things; likewise, whenever needed, the software controlling the behavior of sensors can be dynamically configured as a result of changes in the functional specifications of business processes.
