Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

QUILT: A Decode/Quantize-Interleave-Transmit Approach to Cooperative Relaying

Christina Fragouli, Suhas Diggavi, Siddhartha Brahma, Ayan Sengupta, I-Hsiang Wang

Physical layer cooperation of a source with a relay can significantly boost the performance of a wireless connection. However, the best practical relaying scheme can vary depending on the relative strengths of the channels that connect the source, relay an ...

On Modeling Terrorist Frauds

Serge Vaudenay

Quite recently, distance-bounding protocols received a lot of attention as they offer a good solution to thwart relay attacks. Their security models at still unstable, especially when considering terrorist fraud. This considers the case where a malicious p ...

Creating Shared Secrets out of Thin Air

Christina Fragouli, Suhas Diggavi, Iris Safaka

Current security systems typically rely on the adversary's computational limitations (e.g., the fact that it cannot invert a hash function or perform large-integer factorization). Wireless networks offer the opportunity for a different, complementary kind ...

Network Coding

Mahdi Jafari Siavoshani

The demand for higher throughput and better efficiency are two important challenges for future communication networks. During the past decades, a lot of research studies have been devoted to investigating and proposing near optimal and efficient schemes an ...

Building Wireless Network Coding Protocols

Lorenzo Keller

This work studies how to build wireless network protocols that achieve better reliability, lower delay and higher throughput than existing alternatives by using network coding and by exploiting the broadcast nature of the wireless channel. In the first par ...

Evaluation of classification algorithms for intrusion detection in MANETs

Aikaterini Mitrokotsa

Mobile Ad hoc Networks (MANETs) are wireless networks without fixed infrastructure based on the cooperation of independent mobile nodes. The proliferation of these networks and their use in critical scenarios (like battlefield communications or vehicular n ...

Network Coding with Computation Alignment

Michael Christoph Gastpar, Naveen Goela

Determining the capacity of multi-receiver networks with arbitrary message demands is an open problem in the network coding literature. In this paper, we consider a multi-source, multi-receiver symmetric deterministic network model parameterized by channel ...

Subspace properties of network coding and their applications

Christina Fragouli, Suhas Diggavi, Mahdi Jafari Siavoshani

Systems that employ network coding for content distribution convey to the receivers linear combinations of the source packets. If we assume randomized network coding, during this process the network nodes collect random subspaces of the space spanned by th ...

Toward one Symbol Network Coding Vectors

Pascal Frossard, Nikolaos Thomos

In this paper, we propose a novel design for network coding vectors that limits the overhead information. Network coding vectors contain information regarding the operations the packets have undergone in the network nodes. They are used at the decoder side ...

Reliable Physical Layer Network Coding

Michael Christoph Gastpar

When two or more users in a wireless network transmit simultaneously, their electromagnetic signals are linearly superimposed on the channel. As a result, a receiver that is interested in one of these signals sees the others as unwanted interference. This ...
