  • LSH project MOSAR (Mastering hOSpital Antimicrobial Resistance and its spread into the community) . Infections caused by antimicrobial-resistant bacteria (AMRB) account for an increasing proportion of healthcare-associated infections, particularly in high-risk units such as intensive care units and surgery; patients discharged to rehabilitation units often remain carriers of AMRB, contributing to their dissemination into longer-term care areas and within the community. The overall objective of MOSAR is to gain breakthrough knowledge in the dynamics of transmission of AMRB, and address highly controversial issues by testing strategies to combat the emergence and spread of antimicrobial resistance, focusing on the major and emerging multi-drug antimicrobial resistant microorganisms in hospitals, now spreading into the community. Microbial genomics and human response to carriage of AMRB will be integrated with health sciences research, including interventional controlled studies in diverse hospital settings, mathematical modelling of resistance dynamics, and health economics. Results from MOSAR will inform healthcare workers and decision-makers on strategies for anticipating and mastering antimicrobial resistance. To achieve these objectives, MOSAR brings together internationally recognized experts in basic laboratory sciences, hospital epidemiology, clinical medicine, behavioural sciences, quantitative analysis and modelling, and health economics. MOSAR brings together 11 institutions recognized for their leadership in these areas, from 10 EU Member or Associated States, as well as 7 SMEs to develop and validate high-throughput automated molecular tools for detection of AMRB. A high level of co-ordination will be obtained through a professionally IT-supported and rigorous management structure, to achieve optimal synergy of the components of MOSAR. We aim to develop and validate rapid testing for AMRB and initiate the clinical trials during the first 18 months of the project, and then to build on the infrastructure to execute the joint research programme.

  • ANR TLCOM project SensLAB . The purpose of the SensLAB project is to deploy a very large scale open wireless sensor network platform. SensLAB's main and most important goal is to offer an accurate and efficient scientific tool to help in the design, development, tuning, and experimentation of real large-scale sensor network applications.

  • ANR RNRT project SVP . The SVP project addresses the understanding, the conception, and the implementation of an integrated ambient architecture that would ease the optimization in the deployment of surveillance and prevention services in different types of dynamic networks. The main objective is to develop an environment which is able to accommodate a high number of dynamic entities completely dedicated to a specific service. Partners: CEA, ANACT, APHYCARE, INRIA, UPMC/LIP6, LPBEM, Thalès.

    A brochure describing the project SVP is available (in french).

  • Worldsens project

  • CNRS project RECAP . Self-adaptive and self-organized are questions of active research in a number of different research communities, ranging from hardware to applications. Many topics must be study such as topology control (addressing, localization, etc.), data communication (broadcasting, routing, gathering, etc.), architecture (hardware, system -OS-, network -communication stacks-, etc.), applications (service lookup, distributed database, etc.). The RECAP project is a CNRS national platform which aims to support research activities in this area.

  • MALISSE is an ARC (Cooperative research initiatives) from INRIA. We believe that for the sake of the credibility of wireless sensor networks and their applicability to a wide range of applications, they should be able to support reliably a number of key functionalities, even in the presence of malicious sensors. Obviously such algorithms need to be themselves adapted to sensor networks and more specifically should take into account sensors’ reduced resources. The objective of this postdoctoral research is to consider the following functionalities in such a setting : (1) collection and aggregation of data observed in the sensor network and their routing to specific nodes ; (2) generation and management of alerts when some of the observed measures reach a given threshold. Obviously, identifying the potential attacks in such a network is an important step of this research. Expected outcomes should be both theoretical (algorithm design and proofs) and practical (simulation and implementation) in order to fully validate the proposed solutions .

  • ACI SECURITE project FRAGILE . The purpose of this ACI is to model (and specify) large-scale systems as distributed systems, in order to estimate in which extend the failure tolerance can be guaranteed in various specific contexts (e.g. sensors, ad hoc, Grid, etc.). In case such a guarantee is theoretically possible, this project will propose implementations that take into account the requirements of execution context. Security of Large-scale distributed systems should not be understood only in terms of AAA (Authorization, Authentication, Accounting) but must also take into account the dependability factor.
    Large-scale systems (Sensor Networks, Grids, Peer to Peer Networks, for instance) typically include several thousands basic elements (computers, processors) endowed with communication capabilities (low power radio, dedicated fast network, Internet). Because of the large number of involved components, these systems are particularly vulnerable to occurrences of failures (permanent, transient, intermittent). One definition of fault tolerance for such Large-scale distributed systems is the ability to sustain network functionalities without any interruption due to node failures. Note that the cause of node failures may be of different nature: lack of power, physical damage, sofware or environmental interference, etc.
    In this ACI, we will consider two different kinds of Large-scale systems . On one hand
    • sensor networks, and on the other hand
    • Large-scale Grids and Peer to Peer systems.

  • IST project WASP (Wirelessly Accessible Sensor Populations). An important class of collaborating objects is represented by the myriad of wireless sensors, which will constitute the infrastructure for the ambient intelligence vision. The academic world actively investigates the technology for Wireless Sensor Networks (WSN). Industry is reluctant to use these results coming from academic research. A major cause is the magnitude of the mismatch between research at the application level and the node and network level. The WASP project aims at narrowing this mismatch by covering the whole range from basic hardware, sensors, processor, communication, over the packaging of the nodes, the organisation of the nodes, towards the information distribution and a selection of applications. The emphasis in the project lays in the self-organisation and the services, which link the application to the sensor network. Research into the nodes themselves is needed because a strong link lies between the required flexibility and the hardware design. Research into the applications is necessary because the properties of the required service will influence the configuration of both sensor network and application for optimum efficiency and functionality. All inherent design decisions cannot be handled in isolation as they depend on the hardware costs involved in making a sensor and the market size for sensors of a given type. Three business areas, road transport, elderly care, and herd control, are selected for their societal significance and large range of requirements, to validate the WASP results. The general goal of the project is the provision of a complete system view for building large populations of collaborating objects. The system incorporates networking protocols for wireless sensor nodes to hide the individual nodes from the application The tangible results of the project are: (1) A consistent chain of energy-sensitive software components, (2) Sets of cross optimised software stacks, (3) Benchmarks and a set of measurements on energy- and code- efficiency, (4) Rules for the design of configurable sensor nodes, and (5) A prototype implementation in one of the three chosen business areas The consortium consists of six industrial partners, one SME, six large research institutes and six universities. All of them have a proven experience with WSNs. The impact on European industry and research comes from the provision of an European alternative to the wireless sensor nodes originating in the US. The WASP results will be well suited for adoption by SMEs. The consortium defines an active programme to approach the appropriate SMEs and to familiarise them with the WASP results.

    A leaflet describing the project WASP is available.

  • COST 295 project DYNAMO (Dynamic Communication Networks). An important class of COST 295 is an action of the European COST program (European Cooperation in the Field of Scientific and Technical Research) inside of the Telecommunications, Information Science and Technology domain (TIST).

    The acronym of the COST295 Action, DYNAMO, stands for Dynamic Communication Networks. The Action is motivated by the need to supply a convincing theoretical framework for the analysis and control of all modern large networks. This will be induced by the interactions between decentralised and evolving computing entities, characterised by their inherently dynamic nature.

  • RNRT project SAFARI . The goal of this project is to develop and deploy hybrid network, services and their integrated architecture. Hybrid networks is the extension of WLAN/cellular networks using ad hoc connectivity, ans they offer obvious benefits. On one hand, they allow an extension of the cellular networks coverage using ad hoc connectivity and on the other hand they provide a global Internet connectivity to ad hoc nodes.

  • RNTL project GASP. Its aim is to offer a portable approach to develop ASP (Application Service Provider) in a Grid oriented context. The main idea of GASP (Grid ASP) is to port and validate real applications and to use on the shelf "portable" software.

  • GSF - PTS - PROJET 2 - Modification of Conference XP

    Here are the functionalities added by ourselves in Conference XP.

    First of all in the Conference API, we have modified the Multicast to Unicast so as to pass the routers on Internet. The Unicast is optimized and the participants do not send an object to all participants but just to the neighbours in a binary tree. Then, the neighbours transfer it to their neighbours until the entire tree have received the message. With this solution, if an error occurs between two participants, the sender has not to send the object again to everybody; it is the machine transferring which sends the object again to this participant.

    The binary tree is an identical array in UdpSender, the update of this array is done when a participant join or leave the venue. At the moment, the array (and the tree) is made in ascending order but after we can imagine an algorithm like pastry (the tree is constructed with the geographical places of the participants).

    The transfer of the packet by the neighbours can be implanted neither in the lawyer UDP nor in RTP because of SSRC, sequence number and timestamp errors. So we have implanted the transfer in RtpStream when the object is constructed and deserialized. By doing this, the recipient of the packet think that the machine which has transferred is the sender. This is working well for a presentation but there was a problem in the chat. Actually, each machine prints any message with the transferors name and not the real sender of the message. So, we have added the name of the sender in the message before sending it.

    Then, we have added several functionalities in the presentation of BarUI. Now, its possible to take notes with the keyboards. Its also possible to save and load the notes (keyboard and other) on a file, and to save the RTDocument in a file.

    We have created a viewer for loading an RTDocument and associated notes to view again a conference without launching BarUI. In this viewer, its possible to export keyboard notes in a text file so as to print it for example.

    Now, a participant can arrive later when a presentation has already started, he automatically receives the entire RTDocument. A participant can ask for the notes of somebody, and then the person chosen receives a request, if he accepts it, his notes will be sent to the other participant.

    The last thing we have implanted is the difference between a teacher and the students. Actually, the person who opens a presentation is designed to be the teacher, if he writes notes, the students see it but the teacher doesnt see students notes. Only the teacher can go on another slide or close the presentation.

    We hope that these functionalities will maybe allow the use of Conference XP in the university in an easier way that it used to be.

  • AUTONET Celtic project : The main focus of AUTONET is to address the concern of operators to lower their operational expenses (OPEX). Since networks are converging towards IP technology, AUTONET will focus on this protocol and more specifically on its latest version : IPv6. AUTONET will work on self-configuration of intelligent routers with respect to several of their key features: Address planning and routing protocols, Security and Quality of service.It is worth noticing that just in adding intelligence into the router, without any additional management device, AUTONET will make the network autonomous. Improving the management of IP networks with self-registration and self-configuration of routers shall not introduce new security weakness into the network. A major concern of the project will be the security and the safety of the solutions considered by AUTONET. Security is a recurrent task of network administration. It must be more and more distributed, pre-emptive and adaptive when detecting suspicious behaviour or events. It must survive and adapt to network configuration changes. AUTONET proposes to study embedded mechanisms to continuously improve the protection of its intelligent routers. These goals of Autonet will be achieved by the definition of new protocols for self-configuration and by improvements in the architecture of routers that will include self-configuration capabilities. Into a pragmatic approach, AUTONET will set-up a test bed to test interoperability of all proposed solutions and their co-existence with legacy systems (non self-configurable routers and TMN platforms).
  • The PROXiTV project is an IST project and aims to build a high quality video content distribution solution for TV channels and telecom operators on ADSL broadband networks. The PROXiTV technical solution addresses the need of providing real interactivity to a large public of home users connected to broadband local loops through PC or TV. The project will experiment on 3 Jet2web ADSL loops (Vienna, Linz, Steyr), a set of new services using high quality video programs from WebFreeTV, a national Austrian company aggregating TV channels for Web accesses, and Eurosport TV. The technical solution, based on multimedia proxy servers and IP transport network, will be managed by a system integrator, SYCOMORE AEROSPATIALE MATRA, with the help of INRIA's expertise in data transport optimization onto networks. use.

  • PRIAMM Project SPHID (Services et programmes pour l'Internet haut débit). Its aim was to design a global framwork for video production and broadcasting of multimedia contends on the Internet.

  • RNRT project AMARRAGE. Its aims were to define, design, implement and validate the new concept of active networks by studying two kinds of applications: multimedia application and network management and to set up national test bed.

  • Developed at INRIA, Scilab is a high-level language, and a problem-solving environment, for system control, signal processing and more generally scientific calculations. Several reasons for Scilab's success can be identified: it is user-friendly, interactive, hight-level programming language, powerful graphics, easy extensible via Scilab packages. If one wants to take advantage of multiple processors, then one must switch to other languages and then must develop expert parallel programming skills. Following the philosophy that has made Scilab successful, the aim of parallel Scilab is to provide reasonable efficiency and alow to spawn Scilab processes on multiple processors of a parallel computer or a network of workstation or PCS, but put the premium on ease of use.

  • OURAGAN is an ARC (Cooperative research initiatives) from INRIA. Its main goal was to build Problem Solving Environments on the Grid and to develop a set of tools to build computational servers. More specifically, we focus on the interaction and the developpemnt of tools suitable for scilab as the end client.

  • CoMPaS is an ARC (Cooperative research initiatives) from INRIA. It's aim was to study multicast protocols and QoS in ad hoc networks and more generally in dynamic networks.
