Abstract—This paper addresses the performance evaluation of Time-Hopping (TH), Direct-
Sequence (DS) and sleeping protocol in LDR-UWB (Low data rate-ultra-wideband) network
in the view of energy consumption of node. The energy lifetime is one of the most 

 Non Destructive Measuring of Root Crop Properties using UWB-RADAR
free download

C Peveling-Oberhag, PS Lammers ,cirg.ageng2012.org
Abstract Rapid assessment of plant parameters in plant breeding requires sensor-systems
working in a non-destructive way. In case of root-crops there is still a lack for fast and reliable
systems for non destructive plant-root analysis. This paper will present an approach for
