An Infrastructure Supporting Considerate Sensor Service Provisioning

The Internet of Things (IoT) aims to integrate the digital world of the Internet with our encompassing physical world. However, existing IoT lacks to provide considerate services, meaning that sensors dynamically "collaborate" to provide context-aware federated sensor data. This paper reports our on-going work developing a sensor service federation and provisioning infrastructure. A novel approach has been presented to build social sensor networks to record and study historical interaction patterns among sensors. A case study is reported to leverage in-memory database to monitor and manage real-time sensor service provisioning. A two-way publish/subscribe pattern on top of a message bus is established to assure scalability of sensor service communication. Workflow provenance is carried by a dynamic virtual device concept that we have introduced. A case study is reported to leverage in-memory database to monitor and manage real-time sensor service provisioning.
