摘要
Semantic Web is an effective technology for intelligent Internet of Things (IoT), where Web Services are commonly used to describe the entity functions in the transaction process. However, as a specification of information processing, conventional Web Services cannot fully meet the needs of execution and control of the transactions on IoT. To facilitate describing entities involved in the transactions on IoT, by extending OWL-S, we propose a specification model of dynamic services for IoT entities. In our model, information of entity status is issued in real-time by the extended structure and is released to the requesters as dynamic services. In this way, the transactions on IoT can be constructed and executed intelligently as needed. Finally, the experimental results demonstrated the effectiveness of the proposed model of dynamic entity services for IoT.
