On the Reduction of Atomic Broadcast to Consensus with Byzantine Faults

André Schiper, Martin Hutle, Zarko Milosevic

We investigate the reduction of atomic broadcast to consensus in systems with Byzantine faults. Among the several definitions of Byzantine consensus that differ only by their validity property, we identify those equivalent to atomic broadcast. Finally, we ...

On the Validity of the Fixed Point Equation and Decoupling Assumption for Analyzing the 802.11 MAC Protocol

Jean-Yves Le Boudec

Abstract—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 e ...

Model misspecification in peaks over threshold analysis

Anthony Christopher Davison, Mária Süveges

Classical peaks over threshold analysis is widely used for statistical modeling of sample extremes, and can be supplemented by a model for the sizes of clusters of exceedances. Under mild conditions a compound Poisson process model allows the estimation of ...

On Noise Insertion Strategies for Wireless Network Secrecy

Emre Telatar, Suhas Diggavi, Etienne Perron

We provide lower and upper bounds on the optimal rate for reliable and secret transmission of a message from one node to another in an arbitrary wireless network with deterministic signal interaction. Certain relay nodes are allowed to insert noise into th ...

Flavor effects in thermal leptogenesis

Steve Blanchet

We review recent developments in leptogenesis on flavor effects. Their account discloses an important connection between the matter-antimatter asymmetry of the Universe and CP violation at low energies. Besides, they modify the upper bound on the neutrino ...

Discrete mixture Models

Michel Bierlaire

Allowing for variations in behaviour across respondents is one of the most fundamental principles in discrete choice modelling, given that the assumption of a purely homogeneous population cannot in general be seen to be valid. Two approaches have classica ...

Identification of an Experimental Hybrid System

Giancarlo Ferrari Trecate

In this paper we present an experimental study in the identification of an industrial hybrid system. Piecewise ARX models, that consist of a number of ARX models, together with the partition of the regressor space into regions where each of the models is v ...

An insensitivity property of Lundberg's estimate for delayed claims

Pierre Bremaud

This short note shows that the Lundberg's exponential upperbound in the ruin problem of non-life insurance with compound Poisson claims is also valid for the Poisson shot noise delayed claims model, and that the optimal exponent depends only on the distrib ...
