An IoTService modelling approach with the capability of binding to business processes

Internet of Things (IoT) enables traditional systems to evolve into a new form of interaction and integration among people, machines, and things. Process-Aware Information Systems (PAIS), supported by Business Process Management (BPM), can provide programming paradigms for IoT's business processes. However, the heterogeneity and continuity of IoT data make it difficult for traditional PAIS to handle continuous events. One of the keys to solving this problem is to encapsulate the processing logic of heterogeneous, streaming IoT data from different sources in a unified manner, generate business events of interest to the business process, and integrate them into the business process. An event-publish/subscribe mechanism-based IoTService model can integrate IoT events into business processes and enable PAIS to respond to physical world changes. Case studies and experimental research have proven this model's effectiveness and efficiency.
