DESCRIPTION:Data acquisition via compressive sensing in wireless sensor ne
 tworks\, Wei Chen\n\nCompressive sensing (CS)\, also called compressed sen
 sing and Sub-Nyquist sampling\, has a surprising property that one can rec
 over sparse signals from far fewer samples than is predicted by the Nyquis
 t-Shannon sampling theorem. Wireless sensor networks (WSN) provide the abi
 lity to monitor various physical characteristics of the real world\, such 
 as sound\, temperature\, humidity\, etc.\, by distributing a large number 
 of inexpensive small devices in the detected environment. We apply CS in W
 SN for the benefit of saving energy\, computing quantity and transmission.
  I will introduce my first year's work on this topic.\n
