Congestion Control for Distributed Hash Tables

Karl Aberer, Jean-Yves Le Boudec, Fabius Klemm

Distributed Hash Tables (DHTs) provide a scalable mechanism for mapping identifiers to socket addresses. As each peer in the network can initiate lookup requests, a DHT has to process concurrently a potentially very large number of requests. In this paper, ...

Ordering Events Based on Intentionality in Cyber-Physical Systems

Jean-Yves Le Boudec, Simon Bliudze, Wajeb Saab, Maaz Mashood Mohiuddin

We consider cyber-physical systems (CPSs) comprising a central controller that might be replicated for high-reliability, and one or more process agents. The controller receives measurements from process agents, causing it to compute and issue setpoints tha ...

Optimal Channel Choice for Collaborative Ad-Hoc Dissemination

Jean-Yves Le Boudec, Milan Vojnovic

Collaborative ad-hoc dissemination of information has been proposed as an efficient means to disseminate information among devices in a wireless ad-hoc network. Devices help in forwarding the information channels to the entire network, by disseminating the ...

On Routing in Distributed Hash Tables

Karl Aberer, Jean-Yves Le Boudec, Fabius Klemm, Sarunas Girdzijauskas

There have been many proposals for constructing routing tables for Distributed Hash Tables (DHT). They can be classified into two groups: A) those that assume that the peers are uniformly randomly distributed in the identifier space, and B) those that allo ...

Online Battery Storage Management via Lyapunov Optimization in Active Distribution Grids

Jean-Yves Le Boudec, Cong Wang, Eleni Stai

We consider low run-time complexity power management in distribution grids with renewable energy sources (RESs) and batteries, where forecasts are unavailable. We propose iterative Lyapunov Real-time Control (iLypRC), a fast online algorithm, which does no ...

Optimal Generation and Storage Scheduling in the Presence of Renewable Forecast Uncertainties

Jean-Yves Le Boudec, Dan-Cristian Tomozei, Nicolas Gabriel Gast

The increase in the penetration of wind in the current energy mix is hindered by its high volatility and poor predictability. These shortcomings lead to energy loss and increased deployment of fast-ramping generators. The use of energy storage compensates ...

Security Measures for Grids Against Rank-1 Undetectable Time-Synchronization Attacks

Jean-Yves Le Boudec, Marguerite Marie Nathalie Delcourt

Time-synchronization attacks on phasor measurement units (PMUs) pose a real threat to smart grids; it was shown that they are feasible in practice and that they can have a nonnegligible negative impact on state estimation, without triggering the bad data d ...

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 ...

An Architecture for Wireless Simulation in NS-2 Applied to Impulse-Radio Ultra-Wide Band Networks

Jean-Yves Le Boudec, Ruben Merz, Jörg Widmer

We present an architecture for implementing a wireless physical layer in a packet-based network simulator. We integrate this architecture in the popular ns-2 network simulator and use it to implement an impulse-radio ultra-wide band (IR-UWB) physical layer ...

Power law and exponential decay of inter contact times between mobile devices

Jean-Yves Le Boudec, Milan Vojnovic

We examine the fundamental properties that determine the basic performance metrics for opportunistic communications. We first consider the distribution of intercontact times between mobile devices. Using a diverse set of measured mobility traces, we find a ...

A Novel Bayesian Impulse Radio Ultra-WideBand Ranging Algorithm

Jean-Yves Le Boudec

We consider the problem of ranging with Impulse Radio (IR) Ultra-WideBand (UWB) radio under weak Line Of Sight (LOS) environments and additive Gaussian noise. We use a Bayesian approach where the prior distribution of the channel follows the IEEE 802.15.4a ...

Experimental Validation of the Usability of Wi-Fi over Redundant Paths for Streaming Phasor Data

Athanasios Giannakopoulos, Jean-Yves Le Boudec, Maaz Mashood Mohiuddin, Miroslav Popovic

Applications performing streaming of phasor- measurement data require low latency and losses from the communication network. Traditionally, such requirements are realized through wired infrastructure. Recently, wireless infras- tructure has gained attentio ...

TDOA Source-Localization Technique Robust to Time-Synchronization Attacks

Jean-Yves Le Boudec, Marguerite Marie Nathalie Delcourt

In this paper, we focus on the localization of a passive source from time difference of arrival (TDOA) measurements. TDOA values are computed with respect to pairs of fixed sensors that are required to be accurately time-synchronized. This constitutes a we ...

On the Necessity of Traffic Shaping for PMU Measurement Data Streams

Jean-Yves Le Boudec, Peng Gao, Dan-Cristian Tomozei, Miroslav Popovic

We study the communication network of an on-campus active distribution network (ADN) that comprises phasor measurement units (PMUs) connected to medium-voltage transformers. Within stringent time delays and with minimal loss the PMUs periodically transfer ...

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

Jean-Yves Le Boudec, Nikodin Ristanovic

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 ...

Worst-Case Delay Analysis of Time-Sensitive Networks With Deficit Round-Robin

Jean-Yves Le Boudec, Seyed Mohammadhossein Tabatabaee

In feed-forward time-sensitive networks with Deficit Round-Robin (DRR), worst-case delay bounds were obtained by combining Total Flow Analysis (TFA) with the strict service curve characterization of DRR by Tabatabaee et al. The latter is the best-known sin ...

Selfish Response to Epidemic Propagation

Jean-Yves Le Boudec

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 ...
