Encrypted DNS double right arrow Privacy? A Traffic Analysis Perspective

Carmela González Troncoso, Sandra Deepthy Siby, Narseo Vallina Rodriguez

Virtually every connection to an Internet service is preceded by a DNS lookup. Lookups are performed without any traffic-level protection, thus enabling manipulation, redirection, surveillance, and censorship. To address these issues, large organizations s ...

Successive Refinement to Caching for Dynamic Requests

Michael Christoph Gastpar, Pinar Sen

In the celebrated coded caching problem studied by Maddah-Ali and Niesen, the peak-traffic network load is to be reduced by first caching some information about contents into individual memories of end users during the off-peak hours and then upon user req ...

Dynamic clustering and propagation of congestion in heterogeneously congested urban traffic networks

Nikolaos Geroliminis, Mohammadreza Saeedmanesh

The problem of clustering in urban traffic networks has been mainly studied in static framework by considering traffic conditions at a given time. Nevertheless, it is important to underline that traffic is a strongly time-variant process and it needs to be ...

Dynamic Routing for Flying Ad Hoc Networks

Dario Floreano, Bixio Rimoldi, Stefano Rosati, Grégoire Hilaire Marie Heitz, Karol Jacek Kruzelecki

This paper reports experimental results on self-organizing wireless networks carried by small flying robots. Flying ad hoc networks (FANETs) composed of small unmanned aerial vehicles (UAVs) are flexible, inexpensive and fast to deploy. This makes them a v ...

Double-diffusive interfaces in Lake Kivu reproduced by direct numerical simulations

Alfred Johny Wüest

Double diffusion transforms uniform background gradients of temperature and salinity into "staircases" of homogeneous mixed layers that are separated by high-gradient interfaces. Direct numerical simulations (DNS) and microstructure measurements are two in ...

Aggregating information from the crowd : ratings, recommendations and predictions

Florent Frédéric Garcin

With an ever-growing amount of data generated on the web, aggregating information from the crowd into meaningful knowledge has become crucial to companies in order to create a competitive edge. Not only companies, but also organizations and governments can ...

How Others Compromise Your Location Privacy: The Case of Shared Public IPs at Hotspots

Jean-Pierre Hubaux, Kévin Clément Huguenin, Nevena Vratonjic, Vincent Bindschaedler

Location privacy has been extensively studied over the last few years, especially in the context of location-based services where users purposely disclose their location to benefit from convenient context-aware services. To date, however, little attention ...

Concurrency and dynamic protocol update for group communication middleware

Olivier Rütti

The last three decades have seen computers invading our society: computers are now present at work to improve productivity and at home to enlarge the scope of our hobbies and to communicate. Furthermore, computers have been involved in many critical system ...

A Predicate-Based Approach to Dynamic Protocol Update in Group Communication

André Schiper, Olivier Rütti

In this paper we study dynamic protocol updates (DPU), which consist in replacing, without interruption, a given protocol during execution. We focus especially on group communication protocols. The paper proposes a methodology to conveniently describe whic ...

Non-cooperative behavior in wireless networks

Mark Felegyhazi

Existing cellular networks are centrally managed and require a tremendous initial investment. With the advancement of new wireless technologies, the operators of traditional networks have to face new competition. New technologies make it possible to provid ...

Structural and Algorithmic Issues of Dynamic Protocol Update

André Schiper, Olivier Rütti

In this paper, we study dynamic protocol update (DPU). Contrary to local code updates on-the-fly, DPU requires global coordination of local code replacements. We propose a novel solution to DPU. The key idea is to add a level of indirection between the ser ...

Large-eddy simulation of the lid-driven cubic cavity flow by the spectral element method

Michel Deville, Emmanuel Leriche, Roland Bouffanais, Daniel Weill

This paper presents the large-eddy simulation of the lid-driven cubic cavity flow by the spectral element method (SEM) using the dynamic model. Two spectral filtering techniques suitable for these simulations have been implemented. Numerical results for Re ...

GosSkip, an Efficient, Fault-Tolerant and Self Organizing Overlay Using Gossip-based Construction and Skip-Lists principles

Rachid Guerraoui, Anne-Marie Kermarrec, Sidath Handurukande, Kévin Clément Huguenin

This paper presents GosSkip, a self organizing and fully distributed overlay that provides a scalable support to data storage and retrieval in dynamic environments. The structure of GosSkip, while initially possibly chaotic, eventually matches a perfect se ...

Dynamic group communication

André Schiper

Group communication is the basic infrastructure for implementing fault-tolerant replicated servers. While group communication is well understood in the context of static groups (in which the membership does not change), current specifications of dynamic ...

On Correctness of Dynamic Protocol Update

Olivier Rütti

Replacing or adding network protocols at runtime is problematic – it must involve synchronization of the protocol switch with ongoing local and network communication. We define a formal mathematical model of dynamic protocol update (DPU) and use it to defi ...

Efficient, self-contained handling of identity in Peer-to-Peer systems

Karl Aberer, Manfred Hauswirth, Anwitaman Datta

Identification is an essential building block for many services in distributed information systems. The quality and purpose of identification may differ, but the basic underlying problem is always to bind a set of attributes to an identifier in a unique an ...
