Abstract:

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, 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.  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 distributed data collection and storage, support for
XML queries, transparently routing queries to data, automatic data
partitioning and replication, efficient and protected sharing of sensor
nodes, privacy features, multi-camera calibration, image stitching,
triggering and actuation, and ease of service authorship.  IrisNet is
currently being used to monitor resource consumption on the 300+ node
PlanetLab network, and in a coastal oceanography application.  This talk
will include a videotaped demo of our IrisNet prototype running a mock
parking space finder service.

Short Bio:

Phil Gibbons received his Ph.D. in Computer Science from the University of
California at Berkeley in 1989. After a one year post-doc at Stanford
University, he joined Bell Labs (originally part of AT&T, later part of
Lucent Technologies). In November 2001, he joined the new Intel Research
lab in Pittsburgh.
