Distributed source coding is one of the key enablers for efficient cooperative communication. The potential applications range from wireless sensor networks, ad-hoc networks, and surveillance networks, to robust low-complexity video coding, stereo/Multiview video coding, HDTV, hyper-spectral and multispectral imaging, and biometrics. The book is divided into three sections: theory, algorithms, and applications. Part one covers the background of information theory with an emphasis on DSC; part two discusses designs of algorithmic solutions for DSC problems, covering the three most important DSC problems: Slepian-Wolf, Wyner-Ziv, and MT source coding; and part three is dedicated to a variety of potential DSC applications. Key features: Clear explanation of distributed source coding theory and algorithms including both lossless and lossy designs. Rich applications of distributed source coding, which covers multimedia communication and data security applications. Self-contained content for beginners from basic information theory to practical code implementation. The book provides fundamental knowledge for engineers and computer scientists to access the topic of distributed source coding. It is also suitable for senior undergraduate and first year graduate students in electrical engineering; computer engineering; signal processing; image/video processing; and information theory and communications.

"In many sensor network applications, the sensor readings are inter-node correlated. In such cases, efficient gathering of sensor readings requires distributed compression. Distributed source coding provides practical solutions for compression of these correlated readings when the appropriate rates for the marginal encoding is known at the sensor nodes. In this thesis, we present a data-gathering technique for sensor networks that exploits correlation between sensor data at different locations in the network. Contrary to distributed source coding, our method does not rely on knowledge of the source correlation model in each node although this knowledge is required at the decoder node. Similar to network coding, our proposed method (which we call Quantized Network Coding) propagates mixtures of packets through the network. The main conceptual difference between our technique and other existing methods is that Quantized Network Coding operates on the field of real numbers and not on a finite field. In this thesis, we study our quantized network coding in both lossless and lossy networks.In the study of lossless networks, we discuss the theoretical foundations for our data gathering technique. By exploiting principles borrowed from compressed sensing, we show that the proposed technique can achieve a good approximation of the sensor readings at the sink node with only a few packets received, and that this approximation gets progressively better as the number of received packets increases. Our first approach is to explain the theoretical foundations for sparse recovery from quantized network coded packets based on an analysis of the Restricted Isometry Property of the corresponding measurement matrices. Extensive simulations comparing the proposed Quantized Network Coding to classic network coding and packet forwarding scenarios demonstrate the delay/distortion advantage of quantized network coding. Furthermore, we discuss the advantages of quantized network coding in a Bayesian scenario where the prior of the sensor readings is available at the decoder node. For such Bayesian scenarios, we also discuss the adaptation of a message passing based decoding algorithm with the aid of simulations.To study the practicality of quantized network coding in lossy networks, we adapt it into the IEEE 802.15.4 standard which characterizes low rate wireless communication for sensor networks. This is done by developing a comprehensive implementation of the PHY and MAC layers of the standard and then adjusting the MAC layer settings to match with our requirements. Our computer simulations using the developed implementation show a significant decrease of the delay in many simulation scenarios. The results obtained using this implementation show more advantages for quantized network coding compared to classic routing based protocols especially for high packet drop rates." --

Wireless ad hoc sensor networks has recently become a very active research subject. Achieving efficient, fault-tolerant realizations of very large, highly dynamic, complex, unconventional networks is a real challenge for abstract modelling, algorithmic design and analysis, but a solid foundational and theoretical background seems to be lacking. This book presents high-quality contributions by leading experts worldwide on the key algorithmic and complexity-theoretic aspects of wireless sensor networks. The intended audience includes researchers and graduate students working on sensor networks, and the broader areas of wireless networking and distributed computing, as well as practitioners in the relevant application areas. The book can also serve as a text for advanced courses and seminars.
