Since 1994, IWQoS has been a very successful series of workshops providing an international forum for the presentation and discussion of new research and ideas on Quality of Service (QoS). Building on the successes of previous workshops, the objective of the workshop is to bring together researchers, developers, and practitioners working in this area to discuss recent and innovative results, and identify future directions and challenges in developing practical systems where predictable and controlled performance is a central requirement. In particular, we look to reconsider and expand the scope of the workshop to include all work related to QoS --- in networking (wired, wireless and sensor networks), operating systems, servers, advanced middleware services (such as grid computing and peer-to-peer systems), and to address relevant technical issues such as availibity, reliability, security, pricing, incentives as well as performance.

Therefore, in addition to traditional IWQoS topics such as service guarantees and resource management, papers offering research contributions related to robustness, resilience, dependability, predictability, security, and incentive engineering in both networking and distributed environments are particularly solicited. Topics of interest include (but not limited to):

We particularly solicit papers in these aspects:

• QoS in peer-to-peer, grid and application-layer overlay networks
• QoS and security in distributed computing environments
• Dependability, availability, resilience and robustness
• Rationality, incentives, microeconomics and self-interests
• QoS in infrastructure-based and ad hoc wireless networks
• QoS in mobile environments
• QoS in wireless sensor networks
• Adaptations and evolutions of QoS
• Measurement-based QoS estimation and verification
• QoS in Intranets and VoIP systems
• Service Level Agreements and QoS
• Server-side QoS and its roles in end-to-end QoS provisioning

We also solicit papers in the following aspects:

• QoS architectures and protocols
• QoS analysis and modeling
• Resource management and admission control
• QoS routing
• QoS pricing and billing
• Measurements, evaluation and experiences with QoS metrics
• Content delivery networks with performance and service guarantees
• QoS in web systems and storage systems
• Programmability and language aspects supporting QoS
• QoS in multimedia systems
• QoS-aware middleware frameworks and services
• Integrated and differentiated services in wide-area networks

IWQoS aims to allow rapid dissemination of research results and to provide fast turnaround. The deadline for papers is therefore as close to the conference as the publishers allow. In the past the workshop has been cross-disciplinary, well focused, with the emphasis on innovation. As a result, a considerable amount of time is devoted to informal discussions. The workshop is a single-track forum spanning two and a half days. It values both theoretical contributions and practical experiences.

Best Student Paper Award

Award will be given at the conference to the best student paper, whose first author is a current student.

Paper Submission

Click here to submit a paper

IWQoS invites submission of manuscripts that present original research results, and that have not been previously published or currently under review by another conference or journal. Any previous or simultaneous publication of related material should be explicitly noted in the submission. Submissions should be full-length papers that are no longer than 20 double-spaced single-column pages with font sizes of 11 or larger, including all figures and references, and must include an abstract of 100 -- 150 words. All papers must be submitted in either Postscript or the Adobe PDF format, and no other formats are accepted by the paper submission web site. Submissions will be judged on originality, significance, interest, clarity, relevance, and correctness. At least one of the authors of each accepted paper must present the paper at IWQoS 2004.

Hot Topics Session

IWQoS 2004 introduces a new Hot Topics Session that serves as a forum to present opinions, views and ongoing work that reflect emerging research directions within the scope of the workshop. The objective of the session is to promote community-wide discussions of ideas that will influence and foster continued research in the field. The session will provide a venue for researchers to present new ideas that have the potential to significantly impact the community in the long term, especially those that are architectural or design-oriented in nature. To organize this session, we solicit short papers describing such an idea; the paper could, for example, expose a new problem, advocate a new solution (that may be work-in-progress in nature), or discuss existing work with an original viewpoint. The short papers are limited to five double-column, single-spaced pages. Accepted papers will be presented in a 15-minute time period, and will be included in the conference proceedings.
