Thunder: Towards practical, zero cost acoustic localization for outdoor wireless sensor networks
- ACM Mobile Computing and Communications Review (MC2R), Special Issue on Localization Technologies and Algorithms
, 2006
"... Abstract--Localization for outdoor wireless sensor networks has been a challenge for real applications. Although many solutions have been proposed, few of them can be used in real applications because of their high cost, low accuracy or infeasibility due to practical issues. In this paper, we propos ..."

sacrificing efficiency in the presence of a high percentage of large ranging errors. To validate and evaluate Thunder, we built an experimental localization system based on the Mica2 platform, which achieved localization errors of about 1 meter in medium scale localization experiments. Localization
Efficient cross-correlation via sparse representation in sensor networks
- In Proceedings of the 11th International Conference on Information Processing in Sensor Networks, IPSN ’12
, 2012
"... Cross-correlation is a popular signal processing technique used in numerous localization and tracking systems for ob-taining reliable range information. However, a practical efficient implementation has not yet been achieved on re-source constrained wireless sensor network platforms. We propose cros ..."

1Sub-Nyquist Sampling: Bridging Theory and Practice
"... [ A review of past and recent strategies for sub-Nyquist sampling] Signal processing methods have changed substantially over the last several decades. In modern applications, an increasing number of functions is being pushed forward to sophisticated software algorithms, leaving only delicate finely- ..."

statement which has had one of the most profound impacts on industrial development of digital signal processing (DSP) systems. Over the years, theory and practice in the field of sampling have developed in parallel routes. Contributions by many research groups suggest a multitude of methods, other than
RICE UNIVERSITY Regime Change: Sampling Rate vs. Bit-Depth in Compressive Sensing
, 2011
"... The compressive sensing (CS) framework aims to ease the burden on analog-to-digital converters (ADCs) by exploiting inherent structure in natural and man-made signals. It has been demon-strated that structured signals can be acquired with just a small number of linear measurements, on the order of t ..."
