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 ...

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 ...

Indoor location for safety application using wireless networks

Phillip Tomé

This paper presents the indoor positioning research activities carried out within the scope of the Liaison project. Most of the work has been performed on WiFi location. WiFi is nowadays widely deployed in buildings such as hotels, hospitals, airports, tra ...

Network Coding Applications

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 deals with wireless and content di ...

Vulnerabilities in Epidemic Forwarding

Jean-Yves Le Boudec, Alaeddine El Fawal

We identify vulnerabilities in epidemic forwarding. We address broadcast applications over wireless ad-hoc networks. Epidemic forwarding employs several mechanisms such as inhibition and spread control, and each of them can be implemented using alternative ...

Island Hopping: Efficient Mobility-Assisted Forwarding in Partitioned Networks

Matthias Grossglauser, Natasa Sarafijanovic-Djukic

Mobile wireless ad hoc and sensor networks can be permanently partitioned in many interesting scenarios. This implies that instantaneous end-to-end routes do not exist. Nevertheless, when nodes are mobile, it is possible to forward messages to their destin ...

The scaling of the broadcast capacity of extended wireless networks with cooperative relays

Michael Christoph Gastpar

We study the scaling of the broadcast capacity for a network with a single source and f(N) cooperative relays where N is the number of destinations and f(.) is an increasing function. We consider random extended networks (the network area goes to infinity ...

A Network Coding Approach to Energy Efficient Broadcasting: from Theory to Practice

Jean-Yves Le Boudec, Christina Fragouli, Jörg Widmer

We show that network coding allows to realize energy savings in a wireless ad-hoc network, when each node of the network is a source that wants to transmit information to all other nodes. Energy efficiency directly affects battery life and thus is a critic ...

Secure Positioning in Wireless Networks

Jean-Pierre Hubaux, Srdan Capkun

So far, the problem of positioning in wireless networks has been studied mainly in a nonadversarial setting. In this paper, we analyze the resistance of positioning techniques to position and distance spoofing attacks. We propose a mechanism for secure pos ...

Game Theory in Wireless Networks: A Tutorial

Jean-Pierre Hubaux, Mark Felegyhazi

The behavior of a given wireless station may affect the communication capabilities of a neighboring one, notably because the radio communication channel is usually shared in wireless networks. In this tutorial, we carefully explain how situations of this k ...
