Abstract: For sharing data and services among human, machine and environment in the Internet of Things(IoT),we designed a data service system, named Distributed Information Sharing Platform (DISP). This system collects and processes a variety of data streams in real time, changing with time and location; controls devices deployed in physical environment; outputs high efficient stable data stream, serving users all over the world. Every user can either share the data stream under certain rightness, or define high-level service components as his will. This paper described the implementation mechanisms of DISP, analyzed the key techniques about real-time, openness, and scalability in detail, and verified the processes and efficiency under a prototype system.
Key words: Internet of hhings, Data service, Data stream, Representational state transfer
