A Demand-Response Calculus with Perfect Batteries

Jean-Yves Le Boudec, Dan-Cristian Tomozei

We consider an electricity consumer equipped with a perfect battery, who needs to satisfy a non-elastic load, subject to external control signals. The control imposes a time-varying upper-bound on the instantaneous energy consumption (this is called ``Dema ...

On Secure and Precise IR-UWB Ranging

Jean-Pierre Hubaux, Jean-Yves Le Boudec, Manuel Flury, Marcin Poturalski, Panagiotis Papadimitratos

To provide high ranging precision in multipath environments, a ranging protocol should find the first arriving path, rather than the strongest path. We demonstrate a new attack vector that disrupts such precise Time-of-Arrival (ToA) estimation, and allows ...

Empirical Performance Evaluation of Data Dissemination Mechanisms for Spot Applications

Jean-Yves Le Boudec, Adel Aziz, Alaeddine El Fawal

We evaluate, by measurements on a real testbed, the performance of networking services required for spot applications. We call a “spot application” an application for smartphones (such as “Ad-hoc Flash Sales”) that disseminates information in a local neigh ...

IR-UWB transmitter

Jean-Yves Le Boudec, Catherine Dehollain, Edmund James Colli-Vignarelli

A generator of very short pulses where a cascade of inverters of arbitrary length characterized in that said inverters are adapted to produce pulses on their power supply line instead of their usual output. ...

Protecting Location Privacy: Optimal Strategy against Localization Attacks

Jean-Pierre Hubaux, Jean-Yves Le Boudec, Reza Shokri, Georgios Theodorakopoulos, Carmela González Troncoso

The mainstream approach to protecting the location-privacy of mobile users in location-based services (LBSs) is to alter the users' actual locations in order to reduce the location information exposed to the service provider. The location obfuscation algor ...

COMMENT ON “MIXING BELIEFS AMONG INTERACTING AGENTS”

Jean-Yves Le Boudec, Javier Gomez Serrano

We comment on the derivation of the main equation in the bounded confidence model of opinion dynamics. In the original work, the equation is derived using an ad-hoc counting method. We point that the original derivation does contain some small mistake. The ...

Traps and Pitfalls of Using Contact Traces in Performance Studies of Opportunistic Networks

Jean-Yves Le Boudec, Nikodin Ristanovic, Georgios Theodorakopoulos

Contact-based simulations are a very popular tool for the analysis of opportunistic networks. They are used for evaluation of networking metrics, for quantifying the effects of infrastructure and for the design of forwarding strategies. However, little evi ...

A Generalized Mathematical Model To Estimate T- and B-Cell Receptor Diversities Using AmpliCot

Jean-Yves Le Boudec, Irina Baltcheva

The efficiency of the adaptive immune system is dependent on the diversity of T- and B-cell receptors, which is created by random rearrangement of receptor gene segments. AmpliCot is an experimental technique that allows the measurement of the diversity of ...

On the Asymptotic Validity of the Decoupling Assumption for Analyzing 802.11 MAC Protocol

Jean-Yves Le Boudec

Performance evaluation of the 802.11 MAC protocol is classically based on the decoupling assumption, which hypothesizes that the backoff processes at different nodes are independent. This decoupling assumption results from mean field convergence and is gen ...

Quantifying Location Privacy: The Case of Sporadic Location Exposure

Jean-Pierre Hubaux, Jean-Yves Le Boudec, Reza Shokri, Georgios Theodorakopoulos

Mobile users expose their location to potentially untrusted entities by using location-based services. Based on the frequency of location exposure in these applications, we divide them into two main types: Continuous and Sporadic. These two location exposu ...

Energy Efficient Offloading of 3G Networks

Jean-Yves Le Boudec, Nikodin Ristanovic

A huge increase in the amount of data consumed by smartphone users is becoming a serious problem for mobile operators. In three years, mobile data traffic in the AT&T's network rose 5000%. The US operators invest 50 billion dollars in their data networks e ...

Demand Response Using Service Curves

Jean-Yves Le Boudec, Dan-Cristian Tomozei

We propose an alternative approach, based on ``service curves", which uses the following two ingredients. (1) The rate at which a consumer may draw power from the grid may be controlled by real time signals. Typical concerned devices would be heating syste ...

Synchronization for Impulse-Radio UWB With Energy-Detection and Multi-User Interference: Algorithms and Application to IEEE 802.15.4a

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

Energy-detection (ED) receivers can take advantage of the ranging and multipath resistance capabilities of impulse-radio ultra-wideband (IR-UWB) physical layers at a much lower complexity than coherent receivers. However, ED receivers are extremely vulnera ...

Satisfiability of Elastic Demand in the Smart Grid

Jean-Yves Le Boudec, Dan-Cristian Tomozei

We study a stochastic model of electricity production and consumption where appliances are adaptive and adjust their consumption to the available production, by delaying their demand and possibly using batteries. The model incorporates production volatilit ...

Quantifying Location Privacy

Jean-Pierre Hubaux, Jean-Yves Le Boudec, Reza Shokri, Georgios Theodorakopoulos

It is a well-known fact that the progress of personal communication devices leads to serious concerns about privacy in general, and location privacy in particular. As a response to these issues, a number of Location-Privacy Protection Mechanisms (LPPMs) ha ...

Energy Consumption Comparison Between Macro-Micro and Public Femto Deployment in a Plausible LTE Network

Jean-Yves Le Boudec, Ramin Khalili, Miroslav Popovic

We study the energy consumptions of two strategies that increase the capacity of an LTE network: (1) the deployment of redundant macro and micro base stations by the operator at locations where the traffic is high, and (2) the deployment of publicly access ...

Distance Bounding with IEEE 802.15.4a: Attacks and Countermeasures

Jean-Pierre Hubaux, Jean-Yves Le Boudec, Manuel Flury, Marcin Poturalski, Panagiotis Papadimitratos

Impulse Radio Ultra-Wideband, in particular the recent standard IEEE 802.15.4a, is a primary candidate for implementing distance bounding protocols, thanks to its ability to perform accurate indoor ranging. Distance bounding protocols allow two wireless de ...

Selfish Response to Epidemic Propagation

Jean-Yves Le Boudec, Georgios Theodorakopoulos

An epidemic spreading in a network calls for a decision on the part of the network members: They should decide whether to protect themselves or not. Their decision depends on the trade off between their perceived risk of being infected and the cost of bein ...

Tracking of Mobile Devices Through Bluetooth Contacts

Jean-Yves Le Boudec, Nikodin Ristanovic, Dang Khoa Tran

We investigate if it is possible to reconstruct a mobile phone’s mobility using its Bluetooth contacts with other mobile devices, some of which are equipped with GPS receivers. Our data mining analysis, based on two different data sets, shows that in certa ...

On the validity of the fixed point equation and decoupling assumption for analyzing the 802.11 MAC protocol

Jean-Yves Le Boudec

Performance evaluation of the 802.11 MAC protocol is classically based on the decoupling assumption, which hypothesizes that the backoff processes at different nodes are independent. A necessary condition for the validity of this approach is the existence ...
