Query-driven data collection and data forwarding in intermittently connected mobile sensor networks
In sparse and intermittently connected Mobile Sensor Networks (MSNs), the base station cannot easily get the data objects acquired by the mobile sensors in the field. When users q...

A Lattice Model for Data Display
We will try to address the need for a formal foundation for visualization by taking an analytic approach to defining D. Since an arbitrary function D: U V will not produce display...
