Approximation for Problems in Multi-User Information Theory

Soheil Mohajerzefreh

The main goal in network information theory is to identify fundamental limits of communication over networks, and design solutions which perform close to such limits. After several decades of effort, many important problems still do not have a characteriza ...

On uncoordinated wireless ad-hoc networks

Alaeddine El Fawal

Emerging pervasive wireless networks, pocket switched networks, Internet of things, vehicular networks and even sensor networks present very challenging communication circumstances. They might involve up to several hundreds of wireless devices with mobilit ...

Information-theoretic secrecy for wireless networks

Etienne Perron

The aim of information-theoretic secrecy is to ensure that an eavesdropper who listens to the wireless transmission of a message can only collect an arbitrarily small number of information bits about this message. In contrast to cryptography, there are no ...

Interference Alignment at Finite SNR: General Message Sets

Michael Christoph Gastpar

Interference alignment has proven to be a powerful tool in characterizing the high SNR behavior of wireless networks. Using this technique, Cadambe and Jafar showed that the sum degrees-of-freedom for the K-user interference channel is K/2 rather than 1 as ...

A Deterministic Approach to Wireless Network Error Correction

Suhas Diggavi

In this paper we consider communication between two special nodes ("source" and "destination") in a wireless relay network, which has malfunctioning or malicious nodes (inserting errors). We develop the model for wireless network communication in the prese ...

Border effects, fairness, and phase transition in large wireless 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 ...

Secure Neighbor Discovery in Wireless Networks: Formal Investigation of Possibility

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski

Wireless communication enables a broad spectrum of applications, ranging from commodity to tactical systems. Neighbor discovery (ND), that is, determining which devices are within direct radio communication, is a building block of network protocols and app ...

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 ...

METHOD AND RECEIVER DEVICE FOR WIRELESS DATA COMMUNICATION THROUGH TEMPORALLY CODED ULTRA WIDEBAND SIGNALS

Pierre-André Farine, Cyril Botteron

The invention concerns a wireless data communication method, wherein a transmitter device (2) having a first broadband antenna (27) transmits ultra wideband coded data signals to a receiver device (3) having a second broadband antenna (37) for receiving th ...
