A Scalable Context-Aware Objective Function (SCAOF) of Routing Protocol for Agricultural Low-Power and Lossy Networks (RPAL)
Sensors 15 (8), 2015
abs doi web bib

In recent years, IoT (Internet of Things) technologies have seen great advances, particularly, the IPv6 Routing Protocol for Low-power and Lossy Networks (RPL), which provides a powerful and flexible routing framework that can be applied in a variety of application scenarios. In this context, as an important role of IoT, Wireless Sensor Networks (WSNs) can utilize RPL to design efficient routing protocols for a specific application to increase the ubiquity of networks with resource-constrained WSN nodes that are low-cost and easy to deploy. In this article, our work starts with the description of Agricultural Low-power and Lossy Networks (A-LLNs) complying with the LLN framework, and to clarify the requirements of this application-oriented routing solution. After a brief review of existing optimization techniques for RPL, our contribution is dedicated to a Scalable Context-Aware Objective Function (SCAOF) that can adapt RPL to the environmental monitoring of A-LLNs, through combining energy-aware, reliability-aware, robustness-aware and resource-aware contexts according to the composite routing metrics approach. The correct behavior of this enhanced RPL version (RPAL) was verified by performance evaluations on both simulation and field tests. The obtained experimental results confirm that SCAOF can deliver the desired advantages on network lifetime extension, and high reliability and efficiency in different simulation scenarios and hardware testbeds.

Energy-network performance trade-off in a slotted IEEE 802.15.4 network with acknowledged uplink transmissions
International Journal of Sensor Networks 17 (4), 2015
abs doi web bib

This paper provides an analysis of the performance of wireless sensor network (WSN) under the beacon-enabled slotted CSMA/CA of IEEE 802.15.4 Standard in non-saturation mode with acknowledged uplink and limited buffers. The performance metrics of a node considered are: Reliability, average throughput per node, average packet delay and average energy consumption. An analytical model of energy is derived and used to analyse the average consumption of node. This model takes into account energy dissipation of the radio unit and also of the processing and the sensor units. All these performance metrics are evaluated with different parameters such as medium access control (MAC) parameters, network density and offer load per node in order to observe their influence and adjust them if necessary to obtain good performance.

The Water Framework Directive requires new tools for a better water quality monitoring
E-WAter, 2012
abs web bib

Our goal is to demonstrate the need to design a new type of environmentally friendly intrumentation to face the challenges of the Water Framework Directive. Rivers are spatially and timely structured ecological systems exhibiting hot spots and hot moments that contribute to their overall health status. However, current programs for monitoring water quality (grab samples and laboratory analysis) are based on sampling strategy that do not take into account the spatial and temporal heterogeneity of a water body. To reflect their actual dynamics, a paradigm shift is essential. This requires the development of new monitoring strategies and therefore new instrumentation. This new instrumentation must be able to measure at time scales appropriate to phenomena monitored and at a cost low enough to allow a sufficiently dense deployment in water bodies. We propose to enhance developing wireless networks of autonomous micro-sensors associated with mathematical processing of the collected data. The distinctive feature of this kind of smart sensor comes from the complete monitoring network expected, associating surface- and ground- waters chemistry, electronics and energy harvesting with smart data processing aiming to represent dynamic of basic ecological functions.

Using OCL to model constraints in data warehouses
International Journal of Technology Diffusion 2 (3), 2011
abs doi web bib

Recent research works propose to use the Object-Oriented (OO) approach such as UML to model data warehouses. First, the present paper overviews these recent OO techniques. They aim to describe the facts and the different analysis dimensions of the data. Second, we will propose a tutorial of the Object Constraint Language (OCL) and we will show how this language can be used to specify constraints in OO-based models of data warehouse. Up to now, OCL has been only applied to describe constraints in software applications and transactional databases. So, we demonstrate in this paper how to use OCL to represent the different types of data warehouse constraints. Our paper is addressed to researchers working in the fields of business intelligence and decision support systems, who wish to learn about the major possibilities that OCL offer in the context of data warehouse, and to find citations that will allow them to learn about this formalism in greater detail. We also provide general information about the possible types of implementation of multi-dimensional models and their constraints.

LiveNode: LIMOS versatile embedded wireless sensor node
Journal of Harbin Institute of Technology, 2007
abs web bib

Nowadays, many wireless sensor nodes having approximately the same features are implemented to support both research and industrial deployments. However, all these wireless sensor nodes have limited capacity and are only adapted to implement simple wireless sensors: temperature sensor, tilt/vibration sensor, sound sensor The domain of wireless sensor applications are huge and many problems are still opened and unsolved. Thus to enlarge the application areas, we propose a versatile wireless sensor node named LiveNode, which enables to implement rapidly a prototype for different domains of applications such as telemedicine (wireless cardiac arrhythmias detection sensor), inter-vehicle communication, environmental data collection etc. We describe the key features of LiveNode and its platform: LivePlatform. We present an industrial project (MobiPlus) using LiveNode. Finally, the results of the application and the ongoing work will be presented.

Use of Sensor Data Warehouse for Soil Moisture Analysis

abs doi web bib

More and more data are collected via sensors. Wireless networks can be implemented to facilitate the collection of sensors data and to reduce the cost of their acquisition. In this chapter, we present a general architecture combining Wireless Sensor Network (WSN) and Spatial Data Warehouse (SDW) technologies. This innovative solution is used to collect automatically sensor’s information and to facilitate the analysis of these data. The WSN used in this application has been deployed by Irstea and tested during several years in vineyards in South of France. The novel contribution presented in this chapter is related to the use of a SDW to manage data produced by geo-referenced sensor nodes. SDW is one of the most appropriate modern technologies for analyzing large data sets at different temporal and spatial scales. This type of databases is a specific category of information system used to integrate, accumulate and analyze information from various sources. These data are usually organized according to a multidimensional schema to facilitate the calculation of indicators. In this chapter, we introduce the development of a SDW storing the data collected by this WSN. The implemented data warehouse can allow users to aggregate and explore interactively data pro-duced by sensors. With this system, it is possible to visualize on a map the results of these aggregations.

Remote continuous cardiac arrhythmias detection and monitoring
Transformation of health care with information technologies (p. 112-120), IOS Press, 2004
abs web bib

The current techniques used to diagnose cardiac arrhythmias such as Holter, Rtest and telemetry systems are partially efficient because they are limited either in time or in space. In this paper, a platform dedicated to the real‐time remote continuous cardiac arrhythmias detection and monitoring is proposed. Such a platform allows to improve the accuracy and the efficiency of the diagnostic of ventricular tachycardia among the high‐risk patients and enables the implantation of ICD to prevent sudden death. The new method allows the patient to lead a normal life while being remotely monitored in real‐time by an ambulatory wireless ECG sensor. When a cardiac arrhythmia is detected a message including a sequence of ECG signals and the patient's images (indoors only) is sent to a remote surveillance server. According to the gravity of the symptom, the cardiologist can intervene in real time or later. The system has been evaluated on some ten patients with regard to heartbeat and cardiac rhythm disturbance. The real‐time results are similar to those offered by HP telemetry systems.

Wireless sensor networks (WSN) are one of the important technologies of the 21st century. Most researchers and technical analysts believe that, in the near future, these micro-sensors will be integrated throughout anywhere of our life. In recent years, IoT and WoT gradually became a very popular and hot topic especially in the area of WSN. However, with the development of IoT, the devices that can provide information can be heterogeneous which generate different issues. In this thesis, we considered the Semantic Web associated to Ontology as a possible solution to solve some of these problems. Technologies of the Semantic Web, such as RDF language, are, for example, used to support the publication of structured data on the Web and their interoperability in the Linked (Open) Data. Besides, the 6LoWPAN (IPv6 over Low power Wireless Personal Area Networks) protocol has allowed the use of IPv6 protocol stack in the field of WSN. The use of this protocol should enable, in theory, to have all the nodes of a WSN individually "visible" from the Internet. So, relying on research works currently performed in the context of the WoT as well as the 6LoWPAN protocol, it should be possible to integrate WSN dedicated to environment and agriculture in the IoT.

Extension of the Semantic Sensor Network Ontology for Wireless Sensor Networks: The Stimulus-WSNnode-Communication Pattern

Wireless Sensor Networks (WSN) are designed to collect large amounts of heterogeneous data to monitor environmental phenomenon. Our aim is to adapt WSN nodes communication to their context, in order to optimize the lifetime of the network. Our description of context and WSN characteristics are based on ontologies. Based upon a critical analysis of existing ontologies which formalize the WSN domain, we determine that the Semantic Sensor Network (SSN) ontology is the most suitable to represent the WSN issues. However, as the communication data policy is not characterized either by SSN or by other ontologies, we propose to enrich the SSN ontology with a new pattern describing communication. In this paper, we will ﬁrst integrate the different concepts related to WSN in the SSN ontology and then we will use the resulting ontology, called Wireless Semantic Sensor Network ontology, in an agri-environmental scenario to illustrate the interest of our approach.

L’ontologie permet ainsi de définir les concepts nécessaires à la description de ces politiques. De plus, elle devra être aussi une composante d’un système d’aide à la décision capable de piloter le RCSF pour optimiser la transmission des données. Notre état de l’art fait une analyse critique des différentes ontologies existantes. Cette analyse porte sur les thèmes et sur les différents usages des ontologies dans les RCSF.

Many recent studies deal with the pesticides. According to their characteristics, good practices in their usage are then essential to avoid any kind of exposure. To answer to this problematic, the development of an application which aims at grouping into the same information system, all the most relevant existing information about this topic, has been investigated. This article presents the followed approach to reach that purpose. The first step is the establishment of a knowledge base in order to build the information system model. This base is elaborated from the different identified sources and from inquiries realized with future users. The second is the development of a module dedicated to the integration of data from several sources. A method to extract information from online databases has then been developed. The integration of other types of information sources is in progress. A configurable interface is finally associated to the information system to display the data according to the end users needs.

Wireless sensors networks (WSN) use can be very interesting in agricultural and environmental data collection. The first WSN generations operated in a continuous data stream mode which generates high energy consumption. This article presents a new WSN platform that limits data exchanges and has an increased lifetime. All of its components are designed in a resource aware mode in relation with energy, memory and processing. This platform is built on wireless sensors, implementing a hardware component-based concept, that allow them to be combined to form a more evolved wireless device. To manage this wireless sensor, a hybrid operating system, both multithreading and based on events, has been developed and is associated to a micro-file system. A WSN management tool is in charge of monitoring the wireless sensors and of the data collection. A first evaluation of this WSN platform has been realised in an agricultural context data collection.

A new management method for wireless sensor networks

The Wireless Sensor Networks (WSN) with their constant evolution, need new management methods to be monitored efficiently by taking into account the context and their constraints such as energy consumption, reliability and remote monitoring. WSN has diverse application domains: smart home, smart care, environmental data collection etc. In order to manage a large scale WSN, several Wireless sensor network Management Tools (WMTs) are developed. Some of them use SNMP protocol like because it is impossible to implement the full compliance classical SNMP standard on each wireless sensor node. Therefore, it is important to develop a new WMT with a restricted SNMP standard dedicated to WSN applications. In this paper, we present a new WMT named LiveNCM: LiveNode Non invasive Context-aware, and modular Management tool. LiveNCM is divided into two main parts: one is centralized on the fixed network structure and another one, distributed on each node. Each part introduces the concept of non-invasive context-aware to reduce data exchanges and diagnoses the wireless sensor node state with few messages. Moreover, nodes are based on a configurable modular architecture enables to adapt to an application and to a local node constraints. LiveNCM is implemented on the LiveNode platform to validate the energy consumption and on a UNIX system to validate the adopted SNMP sub-agent. Ultimately, a decreasing data exchange and an improvement in the energy consumption in the entire WSN were observed. An implementation of the proposed management method is presented.

Les évolutions technologiques des dernières années ont permis de mettre en évidence un nouveau domaine de recherche : les Réseaux de Capteurs Sans Fil (RCSFs). Les RCSFs sont basés sur des systèmes embarqués à fortes contraintes de ressources telles que l'énergie, la puissance de calcul et la mémoire. Leurs domaines d'application sont vastes allant notamment de la collecte de données environnementales à la surveillance d'infrastructures en passant par l'aide aux personnes. Nos recherches portent sur l'utilisation de cette nouvelle technologie au service de l'agriculture et de l'environnement pour collecter des données agri-environnementales et proposer des solutions d'intégration de données. Les informations ainsi récoltées sont intégrées dans un système d'information et d'aide à la décision capable d'appliquer des traitements plus complexes et d'aider l'utilisateur dans ses politiques de gestion. Les RCSFs sont encore peu déployés de manière permanente en raison de la complexité de leur fonctionnement et des nombreuses problématiques restantes (gestion énergétique, routage des informations, etc.). Dans le cadre d'applications agri- environnementales, les RCSFs sont utilisés pour couvrir de larges zones afin d'avoir une vision globale à distance. Pour répondre à cette demande, nous développons un système embarqué à faible consommation. Son but est de récolter les données et de les transmettre à distance de manière fiable. Cette plateforme a pour ambition de couvrir une saison entière de culture sans aucune intervention sur les nuds. Pour cela, sa consommation énergétique a été soigneusement étudiée pour maximiser son autonomie. Dans le cadre de nos travaux, nous utilisons les RCSFs pour pallier au manque d'infrastructure filaire. Des nuds passerelles permettent d'étendre le réseau sur plusieurs parcelles sans nécessité de lourds travaux. L'une de nos applications propose une solution de pilotage de l'irrigation à distance en fonction des relevés capteurs. L'administration de tel réseau demande de prendre en compte l'ensemble des contraintes possibles avant de le mettre en place. Par ailleurs, la mise à disposition des données récoltées à l'utilisateur reste un point sur lequel des travaux devront être menés afin d'intégrer cette nouvelle source d'information dans un système d'information central.

A new information system for tracing geolocations of bovine cattle
Atelier Systèmes d'Information et de Décision pour l'Environnement, INFORSID 2009, 26/05/2009, Toulouse, FRA (p. 11), 2009
abs pdf bib

The present paper describes the main idea of a new information system architecture dedicated to the animal geolocation acquisitions. It is applied to traceability of beefs in Brazil. In case of sanitary alerts, the system should be able to determine the animals which have been in contact with a diseased animal. This proposal is issued from studies undertaken in the project OTAG supported by the European Union. OTAG focuses on improving methods and geotechnologies for recording reliable and accurate data on beef production. OTAG develops an operational geo-decisional system to track and trace the mobility, provenance, and state of beef cattle. The presented method enables the acquisition of animal geolocations at a large scale. It minimizes the quantity of devices equipped on animals, and consequently the global economical and energetic costs of the system.

Beef cattle is a product of great importance for the economy of countries like Brazil, one of the major producer and exporter in the world. However, to maintain itself on this important economic position, Brazil needs constantly to improve its production systems as well to invest in aspects related to sanitary control, according to the requirements of the consuming market like the European Community. The goal of OTAG (Operational Management and Geodecisional Prototype to Track and Trace Agricultural Production) project is to provide conditions to know the relative risks concerning to the bovine traceability, in the context of Southern Cone Countries and the EU policies. The project is based on the existing knowledge in Europe and Canada concerning to information systems and geodecisional tools, as well to the interaction among experts and user groups from South Cone, Canada and Europe. The goal of this project was to prove the feasibility of an Information system tracing a bovine all along its live. For what, an electronic devices has been conceived for acquiring the animal geolocation in the herd. This information is associated to data about farm management, such as feeding and production systems in use. This paper presents the characteristics, tools and phases related to the development of the information system prototype for the OTAG project, which has capacity to provide support for animal geolocation data, production system data, and data analysis using business intelligence technologies.

En agriculture, les réseaux de capteurs sans fil vont voir leur rôle devenir de plus en plus prépondérant. Ils devront surveiller les parcelles agricoles et avertir les exploitants des différents besoins de celle-ci (eau, engrais, traitement). En revanche la dispersion géographique des parcelles oblige de mettre au point des moyens de collecte des données à longue distance pas forcément compatibles avec les capacités énergétiques limitées des réseaux de capteurs sans fil. Les travaux présentés, proposent une solution utilisant les engins d'intervention sur les parcelles comme passerelles entre les réseaux de capteurs et les points de collecte de l'information. Ces passerelles mobiles utilisent des antennes directives asservies afin de pouvoir communiquer sur de longues distances.

Wireless sensor performance is highly correlated with available resources use. Resource awareness is more and more a key concept in WSN (Wireless Sensor Network). The increase of available on chip memory reveals the necessity to manage it efficiently. This article presents LiveFile (LIMOS Versatile Embedded File System) an interrogative micro-file system integrated to LIMOS (LIghtweight Multi-threading Operating System). LiveFile merges a micro-file system and an interrogative data system. It applies essentially on Flash memory.

Nowadays, many wireless sensor nodes having approximately the same features are implemented to support both research and industrial deployments. However, all these wireless sensor nodes have limited capacity and are only adapted to implement simple wireless sensors: temperature sensor, tilt/vibration sensor, sound sensor The domain of wireless sensor applications are huge and many problems are still opened and unsolved. Thus to enlarge the application areas, we propose a versatile wireless sensor node named LiveNode, which enables to implement rapidly a prototype for different domains of applications such as telemedicine (wireless cardiac arrhythmias detection sensor), inter-vehicle communication, environmental data collection etc. We describe the key features of LiveNode and its platform: LivePlatform. We present an industrial project (MobiPlus) using LiveNode. Finally, the results of the application and the ongoing work will be presented.

LIMOS: a tiny real-time micro-kernel for wireless objects
2nd IEEE International Conference on Wireless Communications, Networking and Mobile Computing (WICOM), Wuhan, CHN, 22-24 September 2006 (p. 4), 2006
abs web bib

TinyOS is a natural event-driven single-task system. It fits for the single-task specific-application but not for the real-time multi-task application; while, SDREAM is a typical distributed real-time micro-kernel. It supports realtime multi-task applications but normally consumes more resources. This paper presents a novel hybrid real-time micro-kernel: LIMOS (LIghtweight Multi-threading Operating System), which combines the features of TinyOS and SDREAM. LIMOS adopts the event & thread two-level architecture and correspondingly has a two-level scheduling policy: event-driven' (high level scheduling for events) and priority-based preemptive' (low level scheduling for threads). LIMOS adopts the LINDA concept: tuple space and IN & OUT primitive-pair for system synchronization &communication.

The Operating Systems (OS) dedicated to Wireless Sensor Network (WSN) are becoming an important research topic in recent years. This kind of OS has two natures: the resource-aware design and the wireless routing capability. This paper presents a Novel Hybrid Operating System (NHOS) dedicated to WSN. It consists of two parts: a hybrid real-time micro-kernel: LIMOS (LIghtweight Multi-Threading Operating System); a dedicated hybrid wireless protocol stack: CIVIC (Cooperative Inter-Vehicle Intelligent Communication). LIMOS combines the advantages of TinyOS and SDREAM. It has tiny resource consumption and supports the distributed real-time multi-thread applications. CIVIC is a context-aware routing protocol which is implemented to support the infrastructure and ad-hoc network, the hybrid MANET protocol and the multi-support wireless access mediums. This paper demonstrates the key features of NHOS.

Les réseaux sans fil avec infrastructure, Ad Hoc ou hybride ont divers domaines d'application tels que l'agriculture, l'armée, les interventions de premier secours, la télémédecine, la communication inter-véhicules,... Les protocoles de routage sont la colonne vertébrale des réseaux sans fil mais, la plupart du temps, ceux-ci sont développés de manière générale et très théorique. OLAR est un protocole basé sur le protocole LAR et a été développé dans le cadre du projet RAHA dont l'objet est d'intégrer des technologies Ad Hoc dans un contexte agricole. Le protocole OLAR, en considérant les obstacles à la communication sans fil, diminue le nombre de paquets transmis dans le réseau. Le but recherché est d'économiser certaines ressources critiques du réseau comme la bande passante disponible. Ainsi, il est possible d'augmenter la capacité totale du réseau et la robustesse de la communication.

IVC based on MANET has attracted the interests of many automobile manufactures and researchers. The MANET in IVC is named as MANETOR(MANET On Road). In this paper, the capacity and packets delivery are investigated. Throught the theoretical analyse of MANETOR, it is clear that the capacity of MANETOR is limited, and a pipe model allowing to estimating the capacity of MANETOR is proposed. With limited capacity, packets delivery is hard in MANETOR. In fact some communication patterns in MANET, such as broadcasting and cross traffic, will impact the packets delivery in MANETOR. The probability model of packet delivery success is evaluted and three methods to improve the PDR(Packets delivery Ratio) of MANETOR are proposed. And they are proved by simulation in ns2.

A New Adaptive Zone filter to estimate rtt in Manet
ACIT 2004, Constantine, ALG , Décembre 2004 (p. 7), 2004
abs web bib

The guaranty of the Quality of Service (QoS) in the Mobile Ad hoc NETwork (MANET) is a need to generalize their deployment [1]. Indeed, the performances of wireless network are related to many parameters: the load of the network, the number of nodes, the state of the radio link, etc. It is very difficult to quantify exactly all these parameters. So, we propose to use the Round-Trip Time (RTT) as an estimator of the network exchange capacity and its available bandwidth. A fine analysis of this estimator based on the theory of EWMA filters is proposed: the Adaptive Zone filter. The purpose of the presented work is to improve the performance of existing algorithms by using a more progressive behaviour than the traditional Flip-Flop filter. The performances of the Adaptive Zone filter are analysed through simulation under OPNET®. The prospects of the RTT estimator utilization are finally clarified.

Many recent research works deal with wireless sensor networks and their various problems. One of them is the management of WSN data. Generally, the two main types of handled data are either those collected using a sensor that measures a physical quantity, or those generated and managed by the operating system. The purpose of this thesis is to propose solutions to this problem. A micro-file system has then been designed from a hybrid real-time kernel which is both a native event-driven and multithreading operating system. This kernel implements a concept that offers an abstraction level for the management and the scheduling of process and events. This concept was adapted, in the micro-file system, in order to achieve data access. The other main characteristic of this micro-file system, in comparison with existing systems, is to merge, within the same system, functionalities about memory management and data interrogation. These two elements, namely the micro-file system and the real-time kernel, associated with a multi-component wireless sensor provide an adaptive platform dedicated to environmental data collection applications. / De nombreux travaux de recherche actuels s'intéressent aux réseaux de capteurs sans fil (RCSF) et à leurs différentes problématiques. L'une d'entre elles est la gestion des données présentes au sein du RCSF.

One of them is the management of WSN data. Generally, the two main types of handled data are either those collected using a sensor that measures a physical quantity, or those generated and managed by the operating system. The purpose of this thesis is to propose solutions to this problem. A micro-file system has then been designed from a hybrid real-time kernel which is both a native event-driven and multithreading operating system. This kernel implements a concept that offers an abstraction level for the management and the scheduling of process and events. This concept was adapted, in the micro-file system, in order to achieve data access. The other main characteristic of this micro-file system, in comparison with existing systems, is to merge, within the same system, functionalities about memory management and data interrogation. These two elements, namely the micro-file system and the real-time kernel, associated with a multi-component wireless sensor provide an adaptive platform dedicated to environmental data collection applications. / De nombreux travaux de recherche actuels s'intéressent aux réseaux de capteurs sans fil (RCSF) et à leurs différentes problématiques. L'une d'entre elles est la gestion des données présentes au sein du RCSF. Généralement, les deux grands types de données manipulées sont soit celles collectées à l'aide d'un dispositif de mesure, soit celles gérées par le système d'exploitation.

OTAG information system
2008
abs web bib

Beef cattle is a product of great importance for the economy of countries like Brazil, nowadays the most important producer and exporter country of beef cattle in the world. However, to maintain itself on this important economic position, Brazil needs constantly to improve its production systems as well to invest in aspects related to sanitary control, according to the requirements of the consuming market like the European Community. The goal of OTAG project is to provide conditions to know the relative risks concerning to the bovine traceability, in the context of Southern Cone Countries and the EU policies. The project is based on the existing knowledge in Europe and Canada concerning to information systems and geo-decisional tools, as well to the interaction among experts and user groups from South Cone, Canada and Europe. OTAG prototype conceives the use of electronic devices for measuring the animal geo-localization in the herd. This information is associated to data about farm management, such as feeding and production systems in use. This paper presents the characteristics, tools and steps concerned to the development of the OTAG information system, aiming to obtain a prototype to analyse the beef cattle traceability under experimental conditions in Campo Grande, Brazil.

CARE S Computer Aided REhabilitation of Sewer networks. WP5 Socio-economic impacts of rehabilitation strategies. Task 5.1: Rehabilitation impacts on socio-economic costs
2005
abs web bib

Knowledge and assessment of social and economic external costs can be useful for assisting decision-making in sewer network rehabilitation. External impacts of both failures and rehabilitation works are relevant criteria. Understanding of public perception and tolerance towards failures or works are needed for external communication and public participation. These are the topics addressed by work package 5 socio-economic impacts of rehabilitation strategies in project CARE-S Computer Aided Rehabilitation of Sewer systems, supported by the European Commission under the 5th Framework Program. This report focuses on the definition and assessment of criteria representing social costs due to sewer network failures, to be considered in a multi-criteria procedure for rehabilitation projects ranking. / La connaissance et l'évaluation des coûts externes sociaux et économiques peuvent être utiles pour aider à la prise de décision en matière de réhabilitation des réseaux d'assainissement. Les impacts externes des défaillances d'une part, des travaux de réhabilitation d'autre part, constituent des critères pertinents à ce titre. Par ailleurs, il est nécessaire de comprendre la perception par le public et sa tolérance vis-à-vis des défaillances comme des travaux, pour permettre la communication avec le public et sa participation. Ce sont là les aspects abordés dans le « work package » 5, sur les impacts socio-économiques des stratégies de réhabilitation, du projet CARE-S Computer Aided Rehabilitation of Sewer systems, soutenu par la Commission Européenne au titre du 5ème Programme Cadre de Recherche et Développement. Ce rapport se focalise sur la définition et l'évaluation de critères représentant les coûts sociaux engendrés par les défaillances des réseaux d'assainissement, critères destinés à être utilisés dans une procédure multi-critère de classement de priorité entre projets de réhabilitation.
