Efficient Broadcasting Using Network Coding

Jean-Yves Le Boudec, Christina Fragouli, Jörg Widmer

We consider the problem of broadcasting in an ad-hoc wireless network, where all nodes of the network are sources that want to transmit information to all other nodes. Our figure of merit is energy efficiency, a critical design parameter for wireless netwo ...

Low-complexity Algorithms for Energy Efficient Broadcasting in Wireless Networks

Jean-Yves Le Boudec, Christina Fragouli, Jörg Widmer

We consider the problem of broadcasting in an ad hoc wireless network, where all nodes of the network are sources that want to transmit information to all other nodes. Our figure of merit is energy efficiency, a critical design parameter for wireless net- ...

Security and Cooperation in Wireless Networks

Jean-Pierre Hubaux, Levente Buttyan

According to most technology pundits, progress in wireless and sensor networks will lead us into a world of ubiquitous computing, in which myriads of tiny, untethered sensors and actuators will communicate with each other. Information technology will thus ...

Diversity Embedded Space-Time Codes

Suhas Diggavi, Sanket Dusad

Rate and diversity impose a fundamental trade-off in wireless communication. High-rate space-time codes come at a cost of lower reliability (diversity), and high reliability (diversity) implies a lower rate. However, wireless networks need to support appli ...

Hardware-efficient steering matrix computation architecture for MIMO communication systems

Carl Christian Sten Dominic Senning, Christoph Studer

Beamforming (BF) improves the error rate performance of multiple-input multiple-output (MIMO) wireless communication systems by spatial separation of the transmitted data streams. Spatial separation is achieved by multiplication of the transmit vector by a ...

Hierarchical Routing in Dynamic $\alpha$-Doubling Networks

Matthias Grossglauser, Suhas Diggavi, Dominique Florian Tschopp

In this paper we formulate the problem of routing over dynamic networks with finite doubling dimension. This is motivated by communication in mobile wireless networks, where the communication graph topology changes over time, but has some geometric propert ...

Towards Reliable Broadcasting using ACKs

Patrick Thiran, Christina Fragouli, Mathilde Durvy

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

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 ...
