IrisNet: Building Internet-Scale Sensor-Enriched Services

Phillip B. Gibbons, Intel Research, Pittsburgh

Previous work on sensor networks has targeted ad hoc wireless networks of closely colocated, resource-constrained scalar sensor motes. Such work has overlooked richer sensor types such as webcams and microphones, which are typically attached to Internet-connected machines with significant computing power and storage. In this talk, we describe IrisNet (Internet-scale Resource-Intensive Sensor Network services), an architecture for wide-area sensor networks based on these more capable sensing nodes. IrisNet provides a common, scalable software infrastructure that enables the flexible creation of sensor-enriched Internet services. Services view an Internet-scale collection of sensors as a single queriable unit: IrisNet transparently provides distributed query processing, networking, caching, and load balancing. Key features of IrisNet include flexible data partitioning, efficient and protected sharing of sensor nodes, low-latency queries, partial match caching, and query-specified freshness tolerances. This talk will include a videotaped demo of our IrisNet prototype running a mock parking space finder service.
