Transmission techniques for relay-interference networks

Christina Fragouli, Suhas Diggavi

In this paper we study the relay-interference wireless network, in which relay (helper) nodes are to facilitate competing information ﬂows over a wireless network. We examine this in the context of a deterministic wireless interaction model, which eliminat ...

Network Coding Fundamentals

Christina Fragouli, Emina Soljanin

Network coding is an elegant and novel technique introduced at the turn of the millennium to improve network throughput and performance. It is expected to be a critical technology for networks of the future. This tutorial addresses the first most natural q ...

Wireless Network Coding: Opportunities and Challenges

Christina Fragouli

Wireless networks suffer from a variety of unique problems such as low throughput, dead spots, and inadequate support for mobility. However, their characteristics such as the broadcast nature of the medium, spatial diversity, and significant data redundanc ...

Bottleneck Discovery and Overlay Management in Network Coded Peer-to-Peer Systems

Christina Fragouli, Suhas Diggavi, Mahdi Jafari Siavoshani

The performance of peer-to-peer (P2P) networks depends critically on the good connectivity of the overlay topology. In this paper we study P2P networks for content distribution (such as Avalanche) that use randomized network coding techniques. The basic id ...

On feedback for network coding

Christina Fragouli

In this paper we examine possible ways that feedback can be used, in the context of systems with network coding capabilities. We illustrate, through a number of simple examples, that use of feedback can be employed for parameter adaptation to satisfy QoS r ...

On capacity of line networks

Christina Fragouli, Daniela Tuninetti, Urs Niesen

We consider communication through a cascade of discrete memoryless channels (DMCs). The source and destination node of this cascade are allowed to use coding schemes of arbi- trary complexity, but the intermediate relay nodes are restricted to process only ...

Towards reliable broadcastingusing ACKs

Christina Fragouli, Mathilde Durvy

We propose a mechanism for reliable broadcasting in wireless networks, that consists of two components: a method for bandwidth efficient acknowledgrnent collection, and a coding scheme that uses acknowledgments. Our approach combines ideas from network cod ...
