This demonstration shows an integrated query processing environment where users can seamlessly query both a data stream management system and a sensor network with one query expression. By integrating the two query processing systems, the optimization goals of the sensor network (primarily power) and server network (primarily latency and quality) can be unified into one quality of service metric. The demo shows various steps of the unified optimization process for a sample query where the effects of each step that the optimizer takes can be directly viewed using a quality of service monitor. Our demo includes sensors deployed in the demo area in a tiny mockup of a factory application.
