Compression Scheme for Wireless Sensor Networks Using a Distributed Source Coding Algorithm Based on Raptor Code
Această lucrare adresează problematica compresiei datelor în re elele de In this paper, the problem of distributed source coding for data compression in wireless sensor networks (WSN) is addressed. To achieve high levels of compression, a complete solution for network architecture, data correlation model and distributed source coding (DSC) algorithm is proposed. DSC is implemented using Raptor ...
متن کاملNetworked Distributed Source Coding
The data sensed by different sensors in a sensor network is typically correlated. A natural question is whether the data correlation can be exploited in innovative ways along with network information transfer techniques to design efficient and distributed schemes for the operation of such networks. This necessarily involves a coupling between the issues of compression and networked data transmi...
متن کاملAn efficient secure channel coding scheme based on polar codes
In this paper, we propose a new framework for joint encryption encoding scheme based on polar codes, namely efficient and secure joint secret key encryption channel coding scheme. The issue of using new coding structure, i.e. polar codes in Rao-Nam (RN) like schemes is addressed. Cryptanalysis methods show that the proposed scheme has an acceptable level of security with a relatively smaller ke...
متن کاملSource-Optimized Clustering for Distributed Source Coding
Motivated by the design of low-complexity distributed quantizers and iterative decoding algorithms that leverage the correlation in the data picked up by a large-scale sensor network, we address the problem of finding correlation preserving clusters. To construct a factor graph describing the statistical dependencies between sensor measurements, we develop a hierarchical clustering algorithm th...
متن کاملRobust Distributed Source Coding with Arbitrary Number of Encoders and Practical Code Design Technique
The robustness property can be added to DSC system at the expense of reducing performance, i.e., increasing the sum-rate. The aim of designing robust DSC schemes is to trade off between system robustness and compression efficiency. In this paper, after deriving an inner bound on the rate–distortion region for the quadratic Gaussian MDC based RDSC system with two encoders, the structure of...
