NC Node Selection Game in Collaborative Streaming Systems

Pascal Frossard, Nikolaos Thomos, Eymen Kurdoglu

Network coding has been recently proposed as an efficient method to improve throughput, minimize delays and remove the need for reconciliation between network nodes in distributed streaming systems. It permits to take advantage of the path and node diversi ...

Network coding of correlated data with approximate decoding

Pascal Frossard, Nikolaos Thomos, Hyung Gon Park

We consider the problem of distributed delivery of correlated data from sensors in ad hoc network topologies. We propose to use network coding in order to exploit the path diversity in the network for efficient delivery of the sensor information. We furthe ...

Routing and search on large scale networks

Dominique Florian Tschopp

In this thesis, we address two seemingly unrelated problems, namely routing in large wireless ad hoc networks and comparison based search in image databases. However, the underlying problem is in essence similar and we can use the same strategy to attack t ...

Degraded Multicasting with Network Coding over the Combination Network

Christina Fragouli, Shirin Saeedi Bidokhti

In this paper, we give a characterization of the rate region for the degraded two message set problem, applied to a combination network with erasure channels. We also provide an algorithm that uses topological information in order to deliver the two messag ...

Function computation via subspace coding

Christina Fragouli, Nikhil Karamchandani

This paper considers function computation in a network where intermediate nodes perform randomized network coding, through appropriate choice of the subspace codebooks at the source nodes. Unlike traditional network coding for computing functions, that req ...

On the Capacity of Non-Coherent Network Coding

Mahdi Jafari, Christina Fragouli, Suhas Diggavi

The min-cut value towards a single receiver in a network with unit capacity edges can be achieved by routing a single bit. The multicast theorem in network coding shows that, the common min-cut value towards N >= 1 receivers can also be achieved using pack ...

Multiple source multiple destination topology inference using network coding

Christina Fragouli

In this paper, we combine network coding and tomographic techniques for topology inference. Our goal is to infer the topology of a network by sending probes between a given set of multiple sources and multiple receivers and by having intermediate nodes per ...

SenseCode: Network Coding for Reliable Sensor Networks

Christina Fragouli, Lorenzo Keller, Emre Atsan

Designing a communication protocol for sensor networks often involves obtaining the "right" trade-off between energy efficiency and reliability. In this paper, we show that network coding provides a means to elegantly balance these two goals. We present th ...
