Automatic Decomposition of IoT Aware Business Processes – a Pattern Approach

The automatic decomposition of Internet of Things (IoT) aware business processes aims at transferring business logic to IoT devices, in order to reduce both the exchanged messages and the battery usage of such devices. Existing approaches are concerned with block structured processes or ignore data flow dependencies, which cannot be easily applied to processes modelled using the Business Process Model and Notation (BPMN). In this paper, we extend our previous proposal by generalizing the patterns we use to identify the parts of the BPMN processes that IoT devices can execute, and to define the decomposition transformation, assuring that decomposed models maintain the flow dependencies of their original counterparts. This generalization allows for the application of the patterns in more situations than our previous work, further reducing the number of exchanged messages and increasing battery lifespan.
