Reconstruction of Network Coded Sources From Incomplete Datasets

Pascal Frossard, Nikolaos Thomos, Eirina Bourtsoulatze

We investigate the problem of recovering source information from an incomplete set of network coded data with help of prior information about the sources. This problem naturally arises in wireless networks, where the number of network coded packets availab ...

Probing the network. Architecturality of Wireless Infrastructure

Selena Savic

Mobile devices and wireless networks have a prominent place in our interaction with the environment and with each other. Like every new technology, it has been a subject to inflated expectations. Scholars, writers, artists and architects have explored how ...

Topology Optimization For Energy-Efficient Communications In Consensus Wireless Networks

Martin Vetterli, Benjamin Bejar Haro

Over the past years there has been an increasing interest in developing distributed computation methods over wireless networks. A new communication paradigm has emerged where distributed algorithms such as consensus have played a key role in the developmen ...

Towards compact and frequency-tunable antenna solutions for MIMO transmission with a single RF chain

Julien Perruisseau-Carrier, Mohsen Yousefbeiki

Recently, a technique called beam-space MIMO has been demonstrated as an effective approach for transmitting multiple signals while using a single RF-chain. In this work, we present novel design considerations and a compact antenna solution to stimulate th ...

Design and Characterization of a Full-Duplex Multiantenna System for WiFi Networks

In this paper, we present an experiment-and simulation-based study to evaluate the use of full duplex (FD) as a potential mode in practical IEEE 802.11 networks. To enable the study, we designed a 20-MHz multiantenna orthogonal frequency-division-multiplex ...

Smashing WEP in A Passive Attack

Serge Vaudenay, Pouyan Sepehrdad, Martin Vuagnoux, Petr Susil

In this paper, we report extremely fast and optimised active and passive attacks against the old IEEE 802.11 wireless communication protocol WEP. This was achieved through a huge amount of theoretical and experimental analysis (capturing WiFi packets), ref ...
