Interactive Free Viewpoint Video Streaming Using Prioritized Network Coding

Pascal Frossard, Nikolaos Thomos, Laura Toni

In free viewpoint applications, the images are cap- tured by an array of cameras that acquire a scene of interest from different perspectives. Any intermediate viewpoint not included in the camera array can be virtually synthesized by the decoder, at a qua ...

Design and Energy Management Optimizations for Wireless Sensor Networks

Mitko Tanevski

Real-time monitoring of the temperature in supermarket refrigerators, testing air quality, detecting presence or position of a person indoors, monitoring the structural integrity of bridges, and measuring soil humidity for precision agriculture are only a ...

Diffusion LMS strategies for parameter estimation over fading wireless channels

Ali H. Sayed

We propose a modified diffusion strategy for parameter estimation in sensor networks where nodes exchange information over fading wireless channels. We show that the effect of fading can be mitigated by incorporating local equalization coefficients into th ...

Highly Dynamic Distributed Computing with Byzantine Failures

Rachid Guerraoui, Anne-Marie Kermarrec, Florian Huc

This paper shows for the first time that distributed computing can be both reliable and efficient in an environment that is both highly dynamic and hostile. More specifically, we show how to maintain clusters of size O(log N), each containing more than two ...

Untrusting network coding

Ghid Maatouk, Christina Fragouli, Vinod Malathidevi Prabhakaran, Yasin Buyukalp

In networks that perform linear network coding, an intermediate network node may receive a much larger number of linear equations of the source symbols than the number of messages it needs to send. For networks constructed by untrusted nodes, we propose a ...

Toward one Symbol Network Coding Vectors

Pascal Frossard, Nikolaos Thomos

In this paper, we propose a novel design for network coding vectors that limits the overhead information. Network coding vectors contain information regarding the operations the packets have undergone in the network nodes. They are used at the decoder side ...

A method and device for predicting faults in an it system

Dejan Novakovic, Dejan Kostic, Marco Canini, Vojin Jovanovic, Olivier Crameri

A method and device for predicting faults in a distributed heterogeneous IT system (100), the method comprising: creating a local checkpoint (19) in an explorer node (10) of said system (100), said local checkpoint (19) reflecting the state of said explore ...

Diffusion networks outperform consensus networks

Ali H. Sayed

Adaptive networks consist of a collection of nodes that interact with each other on a local level and diffuse information across the network to solve estimation and inference tasks in a distributed manner. In this work, we compare the performance of two di ...

On the efficiency of routing in sensor networks

Florian Huc

In sensor networks, a key efficiency measure for routing protocols is the stretch of the computed paths, where the stretch is the ratio of the path length and the Euclidean distance covered. In the literature, many protocols have been evaluated via extensi ...

PANOPTIC An Interconnected Network of Cameras

Kerem Seyid

Multi-camera systems have attracted attention in recent years due to rapidly dropping cost of digital cameras. This has enabled wide variety of new research topics and applications for Multi View Imaging (MVI) systems. Virtual view synthesis, high performa ...
