RDSS: A Framework for Real-time Data Stream Service Based on Distributed Sensor Networks in Observing System

Observing system have attracted strong attention in recent years and much of real-time data is generated by those systems. Real-time data stream management is an important part of observing system. Despite significant progress has been made in sensor-based observing system, there are still some challenges to provide real-time data stream for various science application scenarios. We address some of the major challenges by proposing three-layer framework named RDSS that can provide real-time data stream for major application scenarios. Our first prototype has been developed to show that the proposed framework has good performance in sensor-based observing system.
