Secure and Private Proofs for Location-Based Activity Summaries in Urban Areas

Jean-Pierre Hubaux, Kévin Clément Huguenin, Igor Bilogrevic, Thi Van Anh Pham

Activity-based social networks, where people upload and share information about their location-based activities (e.g., the routes of their activities), are increasingly popular. Such systems, however, raise privacy and security issues: the service provider ...

Mobile and static sensors in a citizen-based observatory of water

Michael Lehning, Wolf Hendrik Huwald, Steven Vincent Weijs, Tristan Jonas Brauchli

Understanding and forecasting water resources and components of the water cycle require spatially and temporally resolved observations of numerous water-related variables. Such observations are often obtained from wireless networks of automated weather sta ...

A Wireless Body Sensor Network For Activity Monitoring With Low Transmission Overhead

David Atienza Alonso, Andreas Peter Burg, Ruben Braojos Lopez, Jeremy Hugues-Felix Constantin, Ivan Beretta

Activity recognition has been a research field of high interest over the last years, and it finds application in the medical domain, as well as personal healthcare monitoring during daily home- and sports-activities. With the aim of producing minimum disco ...

Secure Wireless Communications via Cooperative Transmitting

Ninoslav Marina

Information-theoretic secrecy is combined with cryptographic secrecy to create a secret-key exchange protocol for wireless networks. A network of transmitters, which already have cryptographically secured channels between them, cooperate to exchange a secr ...

On the probability of extinction of the Haiti cholera epidemic

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Flavio Finger, Marino Gatto

Nearly 3 years after its appearance in Haiti, cholera has already exacted more than 8,200 deaths and 670,000 reported cases and it is feared to become endemic. However, no clear evidence of a stable environmental reservoir of pathogenic Vibrio cholerae, th ...

Spatial Degrees of Freedom of Large Distributed MIMO Systems and Wireless Ad Hoc Networks

Olivier Lévêque

We consider a large distributed MIMO system where wireless users with single transmit and receive antenna cooperate in clusters to form distributed transmit and receive antenna arrays. We characterize how the capacity of the distributed MIMO transmission s ...

Compute-and-Forward: Multiple Bi-directional Sessions on the Line Network

Michael Christoph Gastpar, Jasper Goseling

Signal superposition and broadcast are important features of the wireless medium. Compute-and-Forward, also known as Physical Layer Network Coding, is a technique exploit- ing these features in order to improve performance of wireless networks. In this pap ...

Exchanging Pairwise Secrets Efficiently

Christina Fragouli, Suhas Diggavi, Iris Safaka

We consider the problem where a group of wireless nodes, connected to the same broadcast domain, want to create pairwise secrets, in the presence of an adversary Eve, who tries to listen in and steal these secrets. Existing solutions assume that Eve cannot ...
