Extending Event Elements of Business Process Model for Internet of Things

For the internet of things application development, there are several projects start to use process engine to integrate sensors and actuators. But in extension of BPMN 2.0 for IoT aspect, most of projects just focused on "Activity", "Pool" and "Resource" elements. Due to many situations of IoT are more suitable modeling with "Event" element in business process model. In this paper, we analyzed the requirements of Event extension for IoT with real scenario about temperature controlling, and we proposed our extensions of Event to fulfill these requirements. At last, we modeled the IoT-aware temperature controlling process with extensions and executed it by process engine.
