Optimization of Correlated Source Coding for Event-Based Monitoring in Sensor Networks
Motivated by the paradigm of event-based monitoring, which can potentially alleviate the inherent bandwidth and energy constraints associated with wireless sensor networks, we con...

Source-Channel Communication in Sensor Networks
Sensors acquire data, and communicate this to an interested party. The arising coding problem is often split into two parts: First, the sensors compress their respective acquired s...

Overlapped Quasi-Arithmetic Codes for Distributed Video Coding
This paper describes Slepian-Wolf codes based on overlapped quasi-arithmetic codes, where overlapping allows lossy compression of the source below its entropy. In the context of s...

Motion compensated refinement for low complexity pixel based distributed video coding
Distributed video coding (DVC) is a new coding paradigm that enables to exploit video statistics, partially or totally at the decoder. A particular case of DVC, Wyner-Ziv coding, ...

Distributed Arithmetic Coding for the Asymmetric Slepian-Wolf problem
Distributed source coding schemes are typically based on the use of channels codes as source codes. In this paper we propose a new paradigm, termed “distributed arithmetic codin...
