Just finished a meeting with some visitors from Nokia. It looks like they are launching a very ambitious program called Sensor Planet, leverage mobile phones as a large scale sensor platform. I have to say it looks pretty exciting!
SensorPlanet is a Nokia-initiated cooperation, a global research framework, on mobile device-centric large-scale Wireless Sensor Networks.
The results of SensorPlanet are 1) a test platform that enables the collection of sensor data on a never seen scale, and 2) a central repository for sharing the collected sensor data for research purposes.
