Today?s common computing hardware?Internet-connected desktop PCs and inexpensive, commodity off-the-shelf sensors such as Webcams?is an ideal platform for a worldwide sensor web. In a worldwide sensor web, users can query, as a single unit, vast quantities of data from thousands or even millions of widely distributed, heterogeneous sensors. Users can also actuate sensors and adapt sensor-feed processing in reaction to sensed data in real time.
IrisNet is a software infrastructure that aims to provide the missing software components for realizing a worldwide sensor web. It supports many features that simplify the task of creating sensor web services that are feature-rich, widely-distributed, high performance, highly scalable, adapt well to usage patterns, and robust against failures. Three services from different application domains currently use IrisNet.
