Conference aims and topics

PDF version of the Call for Papers

RTNS is a friendly conference with a great sense of community that presents excellent opportunities for collaboration. The purpose of RTNS is to share new ideas, experiences and information among academic researchers, developers and service providers in the field of real-time systems and networks. Original unpublished papers on all aspects of real-time systems are welcome. These include, but are not limited to:

Papers will be published in edited proceedings with an ISBN and indexed by the ACM digital library.

Full papers must be submitted electronically via EasyChair in a pdf format. The material must be unpublished and not under submission elsewhere. Submissions must be in the same format as in the final published proceedings (10 pages maximum, 2 columns, 10 pt). Papers exceeding the page limit will not be reviewed. Note that this year, the submission deadline will be set as late as possible and will not be extended.

A selection of the best papers will be identified as outstanding papers, and will be highlighted as such in the conference proceedings. These papers will form the shortlist for a best paper award, which will be presented at the conference. Authors of outstanding papers of RTNS 2014 will be invited to submit extended versions to a special issue of the journal Real-Time Systems. There will also be awards for best student paper and for best presentation.

RTNS2014 > Submission

Instructions to authors

Papers are limited to 10 two-column pages in a font no smaller than 9-points.

The corresponding templates are here:

Authors submitting a paper to RTNS 2014 confirm that neither the paper, nor a version of it, is under submission elsewhere nor will be submitted elsewhere before notification by RTNS 2014, and that if the paper is accepted, at least one author will register by the special registration deadline, and present the paper at the conference.

Keynote Talk

RTNS - Industrial needs

Liliana's picture Gérard Cristau (Thales Research & Technology, France)


Thales is developing Real-Time Systems for a variety of domains, ranging from space (satellites), ground transport (railways control systems) and air transport (avionics, air traffic control). This talk will highlight some of the technical and scientific challenges emerging from cross-domain industrial needs, in terms of computing architectures and engineering of embedded systems for future products.

    How to reach the location of the conference

    Versailles is located in the south-west of Paris (17km). You can use this link to compute your itineary.

    By plane
    Versailles is linked by motorway to two international airports. To the north of Paris, ROISSY CHARLES DE GAULLE is 40 km away. To the east of Versailles, ORLY is 25 km away.
    From ROISSY CHARLES DE GAULLES, RER B to Saint Michel Notre Dame then RER C to Versailles Rive Gauche. From ORLY, take the OrlyVal to Anthony, then RER B to Massy Palaiseau, change and take RER C towards Versailles Rive Gauche.

    By train
    From Paris Gare du Nord and Gare de l'Est, RER B to Saint Michel Notre Dame then RER C to Versailles Rive Gauche (to reach Gare du Nord from Gare de l'Est you can use subway lines 4 or 5 or simply walk). From Paris Montparnasse, SNCF trains to Versailles Chantiers train station. From Paris Saint Lazare, SNCF train to Montreuil or Versailles Rive-Droite. From Paris Gare de Lyon, RER C or A to Châtelet les Halles then RER C to Versailles Rive Gauche.

    Be careful, make sure to buy "Versailles" ticket when using RER or trains. T+ tickets are not valid (they are valid only within Paris or on Versailles buses). Here is a link to a map of the RER lines from RATP.

    Below is a map showing bus lines that can be used to reach RTNS from main railway stations of Versailles.

    A link to this map can be found here.

    The public transporter of Versailles is called Phebus. A map of all Phebus lines is available here and timeschedules are available here.

    RTNS2014 > Accomodation


    The organizing committe has negogiated the rate you have to pay for a room in three hotels in Versailles, near the conference. The rate is 90 € for a single room and 45 € for a twin room. The normal rate for a room in Versailles is slightly higher than these prices.
