Using BPMN to model Internet of Things behavior within business process

Whereas, traditionally, business processes use the Internet of Things (IoTs) as a distributed source of information, the increase of computational capabilities of IoT devices provides them with the means to also execute parts of the business logic, reducing the amount of exchanged data and central processing. Current approaches based on Business Process Model and Notation (BPMN) already support modelers to define both business processes and IoT devices behavior at the same level of abstraction. However, they are not restricted to standard BPMN elements and they generate IoT device specific low-level code. The work we present in this paper exclusivelly uses standard BPMN to define central as well as IoT behavior of business processes. In addition, the BPMN that defines the IoT behavior is translated to a neutral-platform programming code. The deployment and execution environments use Web services to support the communication between the process execution engine and IoT devices

Enabling integration and aggregation of context information into WS-BPEL processes

Previously, techniques of Context-Aware Computing were limited only to small scale monolithic applications due to the lack of standardized technologies which could support interoperability of services owned by different organizations. The advancement in Service-Oriented Computing technology allowed autonomous and heterogeneous applications to be exposed as Web Services and interconnected into service compositions exploiting well-agreed interfaces, protocols and message formats. The Web Service Business Process Execution Language (WS-BPEL) is the de-facto standard for composing reusable Web services. To enable handling of context information in applications, context information has to be made available within service compositions; hence, integrated in WS-BPEL processes. Through this means, new innovative context-enriched services can be built and provided using the convergence of context-aware computing and workflow technology. In this diploma thesis, context information provided by the C-CAST Context Management Framework and Google Maps Web services, is integrated into WS-BPEL, and business modelers are supported with the creation of context-based compositions. After surveying some of the current best practice and relevant literature in this area, this thesis presents a solution to this problem based on the Integration Process Pattern work previously done at the Institute of Architecture of Application Systems at the University of Stuttgar
