Cooperative coding on orthogonal information networks

The focus of this thesis is on communication over cooperative information networks. In the first half of the thesis, we consider lossy source coding problems where a relay assists in the communication of a source stream between two terminals. The following ...

A multi-band PLL based tuning circuitry for the super-regenerative IR-UWB receiver system

Catherine Dehollain, Michel Declercq

The impulse radio-ultra wide band (IR-UWB) signalling format has been an attractive mode for wireless communication in wireless sensor node system. The super-regenerative principle can be used for impulse reception for its inherent advantages. The oscillat ...

On the Fairness of Large CSMA Networks

Patrick Thiran, Olivier Dousse, Mathilde Durvy

We characterize the fairness of decentralized medium access control protocols based on CSMA/CA, such as IEEE 802.11, in large multi-hop wireless networks. In particular, we show that the widely observed unfairness of the protocol in small network topologie ...

End-to-end adaptation scheme for ubiquitous remote experimentation

Denis Gillet, Christophe Salzmann, Philippe Müllhaupt

Remote experimentation is an effective e-learning paradigm for supporting hands-on education using laboratory equipment at distance. The current trend is to enable remote experimentation in mobile and ubiquitous learning. In such a context, the remote expe ...

Ultra-low power metal oxide gas sensor on plastic foil

Nico de Rooij, Danick Briand, Jérôme Courbat

We report on the design and fabrication of ultra-low power metal-oxide (MOX) gas sensors on plastic foils envisioning their fabrication at large scale and low cost. A complete sensor solution is presented including its packaging at the foil level and the d ...

Acoustic sensor network design for position estimation

Volkan Cevher

In this paper, we develop tractable mathematical models and approximate solution algorithms for a class of integer optimization problems with probabilistic and deterministic constraints, with applications to the design of distributed sensor networks that h ...

Interference-Resilient Information Exchange

Rachid Guerraoui, Seth Gilbert

This paper presents an efficient protocol for reliably exchanging information in a single-hop, multi-channel radio network subject to unpredictable interference. We model the interference by an adversary that can simultaneously disrupt up to t of the C ava ...

A Distortion-based Metric for Location Privacy

Jean-Pierre Hubaux, Murtuza Jadliwala, Julien Freudiger, Reza Shokri

We propose a novel framework for measuring and evaluating location privacy preserving mechanisms in mobile wireless networks. Within this framework, we first present a formal model of the system, which provides an efficient representation of the network us ...

Code Construction for Multiple Sources Network Coding

Christina Fragouli, Suhas Diggavi

In several wireless applications multiple sources transmit information to one or more receivers, many times over unknown topologies. This is especially so in mobile networks where learning the topology may have prohibitive complexity. Network coding techni ...

Cooperative spectrum sensing via coherence detection

Ali H. Sayed

Efficient and reliable spectrum sensing plays a critical role in cognitive radio networks. This paper proposes a cooperative sensing scheme that detects the existence of a common signal component in the signals received by multiple geographically distribut ...
