Online Estimation of Battery Lifetime for Wireless Sensors Network

Battery is a major hardware component of wireless sensor networks. Most of them have no power supply and are generally deployed for a long time. Researches have been done on battery physical model and their adaptation for sensors. We present an implementation on a real sensor operating system and how architectural constraints have been assumed. Experiments have been made in order to test the impact of some parameter, as the application throughput, on the battery lifetime

jYang : A YANG parser in java

The NETCONF configuration protocol of the IETF Network Work- ing Group provides mechanisms to manipulate the configuration of network devices. YANG is the language currently under consideration within the IETF to specify the data models to be used in NETCONF . This report describes the design and development of a syntax and semantics parser for YANG in java

IP Simulator User Guide

This simulator allows to construct IPv4 network topologies with routers and end hosts. The focus of the simulator is on routing table configuration. The simulator could also run user network programs written with a java.net UDP like API

Data Link Layer Protocol Simulator User Guide

The data link layer protocol simulator allows to write protocol and to see them in execution. This guide describes a step by step approach from simple information communication without any control to windows protocols. A protocol oriented java API is defined to write protocol algorithms

Des recherches ont été menées sur les modèles physique des batteries et leur adaptation pour les capteurs. Nous présentons une implantation sur un véritable système d'exploitation de capteurs et comment les contraintes d'architecture ont pu être pris en compte. Des expériences ont ensuite été menées pour tester l'influence de certains paramètres comme le débit d'application sur la durée de vie des batterie

A Java based Implementation of a Network Level Information Model for the ATM / Frame Relay Interconnection

Colloque avec actes et comité de lecture. internationale.International audienceIn this presentation, we illustrate the use of the Java technology to implement a network information model which captures the essence of the ATM and Frame Relay Interconnection. We show how the TMN concepts stay valid and how the existing and extended information models can be reused and implemented according to the TMN principles in a full Java environment

Simulation interactive du modèle de gestion d'interconnexion de commutateurs à l'aide de LOBSTERS et MODE

En raison de la complexité croissante des modèles de l'information basés sur l'approche OSI, les concepteurs de catalogues d'objets gérés expriment des besoins de mise en oeuvre de méthodes formelles pour valider les aspects liés au comportement de leurs spécifications. Dans le cadre d'une étude sur l'adéquation des méthodes formelles et outils existants pour la spécification des systèmes aux besoins des modèles de gestion de réseaux OSI, nous étudions plusieurs Techniques de Description Formelles et les outils disponibles. Ce rapport présente l'utilisation du langage LOBSTERS ainsi que les outils MODE et CRUSADE pour la validation par simulation interactive du modèle de gestion de la configuration de l'interconnexion de commutateurs. Cette approche propose une alternative à une étude sur l'utilisation du logiciel MEC que nous avions faite sur le même modèle

Managing concurrent QoS assured Multicast sessions using a Programmable Network Architecture

Colloque avec actes et comité de lecture. internationale.International audienceIn this paper we address the management of concurrent multicast sessions with security and QoS guarantees. Their main feature is a high degree of change in terms of membership, implying the necessity for fast reconfiguration and provisioning. We will approach the management problem using techniques developed in the context of virtual private networks, adapted to the high dynamicity that we are confronted with. We propose a framework for the management of such networks by integrating the management and the control plane, using the programmable and active networks paradigms developed within the research community. We apply the framework to the management of residential user TV multicast, where an ATM based access network supports the delivery of TV content to all clients having subscribed to a DVPN
