A mobiscope is a federation of distributed mobile sensors into a taskable sensing system that achieves high-density sampling coverage over a wide area through mobility. Mobiscopes affordably extend into regions that static sensors cannot, proving especially useful for applications that only occasionally require data from each location. They represent a new type of infrastructure—virtual in that a given node can participate in forming more than one mobiscope, but physically coupled to the environment through carriers, including people and vehicles. Mobiscope applications include public-health epidemiological studies of human exposure using mobile phones and real-time, fine-grained automobile traffic characterization using sensors on fleet vehicles.

Well worth a read if you're into sensors!
