Ultra-wideband (UWB) technology is now becoming
mature enough to play a crucial role in a large variety of
pervasive wireless sensor network applications. One of these
applications is represented by land seismic exploration for oil
and gas reservior. Seismic exploration requires a large number
(2000 nodes/sqkm) of sensors to be deployed in outdoor over
large areas (typ. 30 sqkm) to measure backscattered wave fields.
A storage/processing unit (sink node) collects the measurements
from all the sensors to obtain an image of the sub-surface in
real-time. The UWB technology is proposed in this paper for
replacing the cable connections between the sensors and the sink.
UWB is the most suitable wireless technology for this application
as it guarantees high data rate over short range links and selflocalization
with sub-meter accuracy. An UWB sensor network
based on Multi-Band OFDM is designed for the specific problem.
Amendmends to ECMA 368 specifications are also identified to
allow for energy aware beaconing and self-localization.
