This work proposes and evaluates a sampling algorithm based on wavelet transforms with Coiflets basis to reduce the data sensed in wireless sensor networks applications. The Coiï...
In a user centered design process, we investigate what context information may be used to augment digital photos with additional meta information. We describe our initial findings...

Shared sensing infrastructures that allow multiple applications to share deployed sensors are emerging and Internet protocol based access for such sensors has already been prototy...
We present Obstacle-aware Virtual Circuit geographic Routing (OVCR), a novel routing mechanism for obstacle-aware wireless sensor networks that uses the obstacle-free path computed...
