Abstract—With the Internet-of-Things (IoT) technologies becoming more mature, the direction of IoT research is moving from single technology to an integration platform. The main purpose of such platform is able to quickly develop, adjust, and deploy IoT-based applications. The IoT-A project conducted by the European Union (EU) has designed an IoT reference architecture model. It contains seven longitudinal Functionality Groups (FGs) complemented by two transversal FGs. In the seven longitudinal FGs, the Business Process Management, Virtual Entity, IoT Service, and Service Organization are the four key FGs, which are basic modules for quickly and easily developing, adjusting, and deploying IoT-aware applications. The components of the Business Process Management FG include Business Process Modeling and Business Process Execution. How to establish an unambiguous IoT-aware Business Process Model is the first problem that needs to be solved. In this paper, the requirements of IoT-aware Business Process Model Notation (BPMN) extensions are first analyzed. Then the four mentioned BPMN extensions with their requirements are compared. Finally, based on the analyzed results and the IoT Domain Model and Information Model, six key concepts called IoT Task, Physical Entity, Virtual Entity, Device, Service, and Resource and its presentation of the IoT-aware Business Process Model are proposed. Hopefully, the work made can make some contributions to describing an IoT-aware Business Process clearly.
