Efficient distributed storage strategy based on compressed sensing for space information network

open access: yesInternational Journal of Distributed Sensor Networks, 2016
This article investigates the distributed data storage problem with compressed sensing in the space information network. Since there exists a performance-energy trade-off, most existing strategies focus only on improving the compressed sensing ...

Finding needles in noisy haystacks [PDF]

open access: yes, 2008
The theory of compressed sensing shows that samples in the form of random projections are optimal for recovering sparse signals in high-dimensional spaces (i.e., finding needles in haystacks), provided the measurements are noiseless.

Distributed Compressive Sensing: A Deep Learning Approach [PDF]

open access: yesIEEE Transactions on Signal Processing, 2016
Various studies that address the compressed sensing problem with Multiple Measurement Vectors (MMVs) have been recently carried. These studies assume the vectors of the different channels to be jointly sparse. In this paper, we relax this condition. Instead we assume that these sparse vectors depend on each other but that this dependency is unknown. We

Low-power distributed sparse recovery testbed on wireless sensor networks [PDF]

open access: yes, 2016
Recently, distributed algorithms have been proposed for the recovery of sparse signals in networked systems, e.g. wire- less sensor networks. Such algorithms allow large networks to operate autonomously without the need of a fusion center, and are ...

Distributed Basis Pursuit [PDF]

open access: yes, 2012
We propose a distributed algorithm for solving the optimization problem Basis Pursuit (BP). BP finds the least L1-norm solution of the underdetermined linear system Ax = b and is used, for example, in compressed sensing for reconstruction.

Real Acceleration of Communication Process in Distributed Algorithms with Compression [PDF]

open access: yes, 2023
Modern applied optimization problems become more and more complex every day. Due to this fact, distributed algorithms that can speed up the process of solving an optimization problem through parallelization are of great importance. The main bottleneck of distributed algorithms is communications, which can slow down the method dramatically.

Energy-Efficient Distributed Compressed Sensing Data Aggregation for Cluster-Based Underwater Acoustic Sensor Networks

open access: yesInternational Journal of Distributed Sensor Networks, 2016
Energy-efficient data aggregation is important for underwater acoustic sensor networks due to its energy constrained character. In this paper, we propose a kind of energy-efficient data aggregation scheme to reduce communication cost and to prolong ...

Distributed Compressed Hyperspectral Sensing Imaging Incorporated Spectral Unmixing and Learning

open access: yesJournal of Spectroscopy, 2022
Compressed hyperspectral imaging is a powerful technique for satellite-borne and airborne sensors that can effectively shift the complex computational burden from the resource-constrained encoding side to a presumably more capable base-station decoder ...

Variational Bayesian algorithm for distributed compressive sensing [PDF]

open access: yes2015 IEEE International Conference on Communications (ICC), 2015
Distributed compressive sensing (DCS) concerns the reconstruction of multiple sensor signals with reduced numbers of measurements, which exploits both intra- and inter-signal correlations. In this paper, we propose a novel Bayesian DCS algorithm based on variational Bayesian inference.
