By embedding sensors in mobile devices, it is possible to exploit the ubiquitous presence of these devices to construct applications for large-scale sensing and monitoring of envi...
- We demonstrate that the network flux over the sensor network provides us fingerprint information about the mobile users within the field. Such information is exoteric in the phys...
A significant and growing class of location-based mobile applications aggregate position data from individual devices at a server and compute aggregate statistics over these posi...
