Unidirectional graph-based wavelet transforms for efficient data gathering in sensor networks

13 years 6 months ago

Download biron.usc.edu

We design lifting-based wavelet transforms for any arbitrary communication graph in a wireless sensor network (WSN). Since transmitting raw data bits along the routing trees in WS...

On optimal communication cost for gathering correlated data through wireless sensor networks

14 years 1 months ago

Download web.sau.edu

In many energy-constrained wireless sensor networks, nodes cooperatively forward correlated sensed data to data sinks. In order to reduce the communication cost (e.g. overall ener...
