The Fourth International Conference on Communication Theory, Reliability, and Quality of Service

CTRQ 2011

April 17-22, 2011 - Budapest, Hungary

Call for Papers

The processing and transmission speed and increasing memory capacity might be a satisfactory solution on the resources needed to deliver ubiquitous services, under guaranteed reliability and satisfying the desired quality of service. Successful deployment of communication mechanisms guarantees a decent network stability and offers a reasonable control on the quality of service expected by the end users. Recent advances on communication speed, hybrid wired/wireless, network resiliency, delay-tolerant networks and protocols, signal processing and so forth asked for revisiting some aspects of the fundamentals in communication theory. Mainly network and system reliability and quality of service are those that affect the maintenance procedures, on the one hand, and the user satisfaction on service delivery, on the other hand. Reliability assurance and guaranteed quality of services require particular mechanisms that deal with dynamics of system and network changes, as well as with changes in user profiles. The advent of content distribution, IPTV, video-on-demand and other similar services accelerate the demand for reliability and quality of service.

The Fourth International Conference on Communication Theory, Reliability, and Quality of Service, CTRQ 2011, continues a series of events focusing on the achievements on communication theory with respect to reliability and quality of service. The conference brings also onto the stage the most recent results in theory and practice on improving network and system reliability, as well as new mechanisms related to quality of service tuned to user profiles.

We welcome technical papers presenting research and practical results, position papers addressing the pros and cons of specific proposals, such as those being discussed in the standard fora or in industry consortia, survey papers addressing the key problems and solutions on any of the above topics short papers on work in progress, and panel proposals.

Industrial presentations are not subject to the format and content constraints of regular submissions. We expect short and long presentations that express industrial position and status.

Tutorials on specific related topics and panels on challenging areas are encouraged.

The topics suggested by the conference can be discussed in term of concepts, state of the art, research, standards, implementations, running experiments, applications, and industrial case studies. Authors are invited to submit complete unpublished papers, which are not under review in any other conference or journal in the following, but not limited to, topic areas.

Posters are welcome. Please submit the contributions following the instructions for the regular submissions using the "Submit a Paper" button and selecting the contribution type as poster.  Submissions are expected to be 6-8 slide deck. Posters will not be published in the Proceedings. One poster with all the slides together should be used for discussions. Presenters will be allocated a space where they can display the slides and discuss in an informal manner. The poster slide decks will be posted on the IARIA site.

For more details, see the Posters explanation page.

Work in Progress

Work-in-progress contributions are welcome. Please submit the contributions following the instructions for the regular submissions using the "Submit a Paper" button and selecting the contribution type as work in progress.  Authors should submit a four-page (maximum) text manuscript in IEEE double-column format including the authors' names, affiliations, email contacts. Contributors must follow the conference deadlines, describing early research and novel skeleton ideas in the areas of the conference topics. The work will be published in the conference proceedings.

For more details, see the Work in Progress explanation page

Technical marketing/business/positioning presentations

The conference initiates a series of business, technical marketing, and positioning presentations on the same topics. Speakers must submit a 10-12 slide deck presentations with substantial notes accompanying the slides, in the .ppt format (.pdf-ed). The slide deck will not be published in the conference’s CD Proceedings. Presentations' slide decks will be posted on the IARIA's site. Please send your presentations to

Proposals must contain the title, the summary of the content, and the biography of the presenter(s). The tutorials' slide decks will be posted on the IARIA's site. Please send your proposals to

Panel proposals:

The organizers encourage scientists and industry leaders to organize dedicated panels dealing with controversial and challenging topics and paradigms. Panel moderators are asked to identify their guests and manage that their appropriate talk supports timely reach our deadlines. Moderators must specifically submit an official proposal, indicating their background, panelist names, their affiliation, the topic of the panel, as well as short biographies.
