The Research on IoT System Construction Method to Support Collaborative Awareness Service

The current IoT (Internet of Things) systems lack the ability of collaborative awareness. Therefore, an IoT system architecture supporting collaborative awareness service is presented. First, in order to hide the heterogeneous factors of IoT, a SOA (Service-Oriented Architecture) based IoT middleware infrastructure is accepted and applied. Then, the components in different levels of middleware platform are designed and described to support dynamic service composition, and provide an event-driven service collaboration mechanism. Finally, the capabilities of the presented architecture to support collaborative awareness service are analyzed and evaluated from three aspects: activity awareness, policy awareness and process awareness. By the presented IoT system infrastructure, the system developers and service process designers can dynamically search, select, and use the real-world services running on physical devices.
