2. The Main Idea
A mobile sensor computing system designed to collect, process, deliver, and visualize data from sensors located on mobile units such as automobiles.

3. The Main Achievements
A working system that has been running on six cars in a small-scale deployment for over a year.
Main contributions:
Extending the notion of continuous queries to handle intermittent connectivity.
Enabling modular upgrades to integrate new sensors and data types
CafNet: “carry-and-forward” delay-tolerant network stack

4. The Challenges Providing a simple application programming interface
Handling intermittent and variable network connectivity: mobile & opportunistic
Handling a large amount of heterogeneous data

5. Pictures

6. Innovation
A synthesis of ideas in mobile system, sensor data management and delay-tolerant networks into a single system.
