21st International Conference on Real-Time Networks and Systems

Sophia Antipolis, France, October 16-18, 2013

RTNS is a friendly conference with a great sense of community that presents excellent opportunities for collaboration.

The purpose of the conference is to share ideas, experiences and informations among academic researchers, developers and service providers in the field of real-time systems and networks.

RTNS 2013 will be in Sophia Antipolis which is located on the French Riviera, close to Nice (28km), Cannes (12km) and Antibes (8km).

RTNS 2013 is the 21st edition of the conference formerly known as RTS (Real-Time Systems, Paris). The first 12 editions of RTS were french-speaking events held in Paris in conjunction with the RTS Embedded System exhibition. Since its 13th edition, the conference language of RTNS has been english.

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 Original unpublished papers on all aspects of real-time systems are welcome.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 The material must be unpublished and not under submission elsewhere.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 (28th June 2013) has been 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 2013 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.

RTNS2013 > Submission

Instructions to authors

Papers are limited to 10 two-column pages in a font no smaller than 9-points. Style guides and templates for LaTeX and Word are available below.

The guidelines for preparing your manuscript are given here. The corresponding templates are here:

Authors submitting a paper to RTNS 2013 confirm that neither the paper, nor a version of it, is under submission elsewhere nor will be submitted elsewhere before notification by RTNS 2013, 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

Probabilistic Real-Time Systems

Liliana's picture Liliana Cucu-Grosjean (INRIA Nancy-Grand Est / INRIA Paris-Rocquencourt, France)

The slides of the keynote are available.

Abstract

Since the early work of Lehoczky on real-time queuing theory, probabilistic approaches have addressed many aspects of real-time systems. This presentation concentrates on the migration of probabilistic methods from modelling soft real-time systems to analysing hard real-time systems. The history of this migration is outlined over the last two decades, advancing under different banners including stochastic, probabilistic and statistical analysis. Here, the shift from the deterministic analysis of single upper bound values to more expressive forms using probability distributions has undermined or modified many classical real-time results, such as the optimality of Rate Monotonic assignment. Two common misconceptions concerning probabilistic real-time systems are discussed: independence and the identical distribution. These properties are less restrictive than is widely appreciated and together with probabilistic worst-case reasoning form the basis of the main results currently proposed for hard real-time systems. The presentation summarises recent state-of-the-art research into probabilistic real-time systems, and concludes with the main open challenges in this area.

Biography

Liliana Cucu-Grosjean is an INRIA researcher, and leader of the TRIO team at the INRIA Nancy-Grand Est joint laboratory with LORIA. She has a degree in Mathematics, an MSc in Physics, and a PhD in Computer Science awarded in 2004 by the University of Paris Sud. Since then she has been active in three major European real-time and embedded systems research groups, in Portugal, Belgium, and France. Starting from September 2013 she will join the AOSTE team at INRIA Paris-Rocquencourt. Liliana has been involved in, and led, numerous national and European projects focused on real-time scheduling, timing analysis and the use of probabilistic and statistical methods. She is at the centre of the recent renaissance in using probabilistic and statistical approaches to analyse hard real-time systems.

Nice to know

Opening/closing hours, public holidays, currency, areas codes for France, Emergency phone numbers, advice for a trouble-free stay...

Climate
The French Riviera benefits from a Mediterranean-type climate, characterised by exceptional sunshine almost 300 days a year and mild temperatures for most of the year.
It rains heavily but infrequently mostly in March/April and October/November. In winter, freezing temperatures are rare, but sweaters are advised.

Opening hours
Shops are usually open from 9 am to 7 pm from Monday to Saturday. Department stores may stay open until 9 pm. Banks are open from 8.30 to 12 noon and 2 to 4.30 pm, Monday to Friday, with some branches opening on Saturday mornings and during lunch time.

On legal holidays, banks, government offices, shops, the majority of businesses and also many museums and tourist attractions are closed.

Money/currency
Credit cards are accepted in many shops, hotels and restaurants (there is usually a minimum amount of between €7 and €15). For cash, you will find cash-points on just about every street corner (24 hours a day).
Bank branches, exchange bureaux and some post offices handle currency exchange transactions and traveller's cheques. Whatever you are buying, prices are net.

Emergency phone numbers

A few tips for a pleasant trouble-free holiday
- You are strongly recommended to respect smoking/no smoking signs in public places.
- It is always useful to have a little cash on you at all times for little out-of-pocket expenses like taxi fares to the airport, drinks, etc.
- A service charge is included in the price of each item on the menu in any cafe or restaurant as required by French law. In theory, no further tipping is expected.
However, it is pretty common to leave something after a bite to eat or drink. But it’s never expected and is only given for good or attentive service, or at a place you habituate frequently. Extra generosity will never hurt.
- If you are driving, park only where authorised and respect speed limits on highways and motorways.
