The role of the virtual channel in distributed source coding of video
In distributed video source coding side-information at the decoder is generated as a temporal prediction based on previous frames. This creates a virtual dependency channel betwee...

An Information Theoretic Analysis of Rooted-Tree Based Secure Multicast Key Distribution Schemes
Several variations of rooted tree based solutions have been recently proposed for member revocation in multicast communications [18, 19, 20, 21]. In this paper, we show that by ass...

Side-information Scalable Source Coding
Abstract—We consider the problem of side-information scalable (SI-scalable) source coding, where the encoder constructs a two-layer description, such that the receiver with high ...

Routing Explicit Side Information for Data Compression in Wireless Sensor Networks
Abstract. Two difficulties in designing data-centric routes [2–5] in wireless sensor networks are the lack of reasonably practical data aggregation models and the high computatio...
