Lattice codes for many-to-one cognitive interference networks

Michael Christoph Gastpar, Jingge Zhu

In this work we consider the cognitive many-to-one interference network. We first extend existing coding schemes from the two-user case to this network scenario. Then we present a novel coding scheme using compute-and-forward and show it can enlarge the ac ...

Function computation via subspace coding

Christina Fragouli, Lorenzo Keller, Nikhil Karamchandani

This paper considers function computation in a network where intermediate nodes perform randomized network coding, through appropriate choice of the subspace codebooks at the source nodes. Unlike traditional network coding for comput- ing functions, that r ...

A Bayesian Approach to Detect Pedestrian Destination-Sequences from WiFi Signatures

Michel Bierlaire, Bilal Farooq, Antonin Danalet

In recent years, interest in crowd dynamics and pedestrian modeling is reviving due to urban growth and its pressure on urban infrastructure. Crowd and pedestrian simulation is emerging as a tool for designing new infrastructures and optimizing the use of ...

Non-Cooperative Location Privacy

Jean-Pierre Hubaux, Julien Freudiger, David C. Parkes

In mobile networks, authentication is a required primitive for most security protocols. Unfortunately, an adversary can monitor pseudonyms used for authentication to track the location of mobile nodes. A frequently proposed solution to protect location pri ...

Game Theory Meets Network Security and Privacy

Jean-Pierre Hubaux

This survey provides a structured and comprehensive overview of research on security and privacy in computer and communication networks that use game-theoretic approaches. We present a selected set of works to highlight the application of game theory in ad ...

Correlation-aware Resource Allocation in Multi-Cell Networks

Pascal Frossard, Dorna Bandari

We propose a cross-layer strategy for resource allocation between spatially correlated sources in the uplink of multi-cell FDMA networks. Our objective is to find the optimum power and channel allocation to the different sources, in order to minimize the m ...

Extracting Mobile Behavioral Patterns with the Distant N-Gram Topic Model

Daniel Gatica-Perez, Katayoun Farrahi

Mining patterns of human behavior from large-scale mobile phone data has potential to understand certain phenomena in society. The study of such human-centric massive datasets requires new mathematical models. In this paper, we propose a probabilistic topi ...

Estimation of Sparse MIMO Channels with Common Support

Martin Vetterli, Ali Hormati, Yann Barbotin

We consider the problem of estimating sparse communication channels in the MIMO context. In small to medium bandwidth communications, as in the current standards for OFDM and CDMA communication systems (with bandwidth up to 20 MHz), such channels are indiv ...
