We propose Pocket Bluff; a novel pocket switched message forwarding protocol that can foil selfish/malicious nodes that deliberately drop data. Pocket Bluff hides the...

A memory model is an important component of the formal semantics of imperative programming languages: it specifies the behavior of operations over memory states, such...

We present our experiment in integrating semantic web services in the existing semantic web server architecture used by the ACACIA team to implement corporate...

In this paper, it is shown that the Gröbner basis (for any monomial ordering) of a zero-dimensional ideal may be computed within a bit complexity which is essentially...

Histograms of local appearance descriptors are a popular representation for visual recognition. They are highly discriminant and they have good resistance to local...

We study here the problem of predicting a functional valued stochastic process. We first explore the model proposed by Antoniadis et al. (2006) in the context of a...

In this work, we propose an ExpSpace tableau-based algorithm for deciding consistency of a knowledge base in the description logic SHOIQ. The construction of this...

We introduce a new class of active contour models that hold great promise for region and shape modelling, and we apply a special case of these models to the extraction...

In this report, we present an analytical model for VoIP capacity in IEEE 802.11e WLAN. We illustrate performance results relative to typical codec rates of G.711 PCM...

This paper studies a class of transport equations arising from stochastic models in congestion control. This class contains two cases of loss point process models: the...

Ad hoc networks are spontaneous wireless networks without any wired infrastructure, composed of mobile terminals. We assume that nodes must collaborate to set up an...

The increased popularity of IEEE 802.11 WLANs has led to dense deployments in urban areas. Such high density leads to sub-optimal performance unless the interfering...

Given a weighted graph $G=(V,E,w)$, we investigate the problem of constructing a sequence of $n=|V|$ subsets of vertices $M_1,...,M_n$ (called groups) with small...

In this paper, we propose a new robust receding horizon control scheme for linear input-constrained discrete-time systems with polytopic uncertainty. We provide a...

In a WDM network, routing a request consists in assigning it a route in the physical network and a wavelength. If each request uses at most $1/C$ of the bandwidth of...

Given two graphs, a fundamental task faced by matching algorithms consists of computing either the (Connected) Maximal Common Induced Subgraphs ((C)MCIS) or the...

Madeleine 4 est une nouvelle implémentation de l'interface de communication multi-protocole Madeleine. Sa particularité consiste en l'introduction d'une couche...

We consider a single TCP session traversing a wireless channel, with a constant signal to noise ratio (SINR) at the receiver. We consider the problem of determining...
