The Workshop on ns-3 (WNS3) will be held on June 28-29, 2023 at the Holiday Inn Arlington at Ballston. The objective of the workshop is to gather ns-3 users and developers, together with networking simulation practitioners and users, and developers of other network simulation tools, to discuss the ns-3 simulator and related activities.

WNS3 2023 is planned to be an in-person workshop. The organizers request that an author from each accepted paper plan to attend in-person. However, accommodations will be made for authors to present virtually if any hardships (such as visa issues, economic or other travel constraints) arise. Portions of WNS3 2023 will be made available either live virtually or with archived recordings. Additional events will be planned during the same week, including developer meetings and the annual ns-3 Consortium meeting, and possibly training and tutorial sessions. More information on this will follow.

The workshop has been accepted to the ACM International Conference Proceeding Series (ICPS), and accepted WNS3 papers will be published in the ACM Digital Library.

Two types of papers may be submitted:

  • Regular papers (7-9 pages)
  • (new for 2023) Short papers (4-6 pages)

In addition (also new for 2023), artifacts for reproducibility will be evaluated. Please read below for the acceptable scope for regular papers, short papers, how artifacts evaluation will be handled, and submission instructions (deadline in early February 2023).

Regular paper submission

WNS3 invites authors to submit original high quality papers presenting different aspects of developing and using ns-3. In such papers, reproducibility and methodology will be a key reviewing criteria, as explained below. Topics of interest include, but are not limited to, the following:

  • new models, devices, protocols and applications for ns-3
  • using ns-3 in modern networking research
  • comparison with other network simulators and emulators
  • speed and scalability issues for ns-3
  • multiprocessor and distributed simulation with ns-3, including use of GPUs
  • validation of ns-3 models
  • credibility and reproducibility issues for ns-3 simulations
  • user experience issues of ns-3
  • frameworks for the definition and automation of ns-3 simulations
  • post-processing, visualisation and statistical analysis tools for ns-3
  • models ported from other simulators to ns-3
  • using real code for simulation with ns-3 and using ns-3 code in network applications
  • integration of ns-3 with testbeds, emulators, and other simulators or tools
  • using ns-3 API from programming languages other than C++ or Python
  • porting ns-3 to unsupported platforms
  • network emulation with ns-3
  • using ns-3 in education and teaching

Papers submitted between 7-9 pages will be reviewed as regular papers and classified as such in the proceedings.

Short paper submission

We solicit novel short papers between 4-6 pages in length, for publishing in the proceedings in a short paper track. Short papers are intended to follow a scope similar to regular papers, but for work that may not be lengthy enough for a 7-9 papge submission. In particular, the following topics are encouraged:

  • Verification, validation, or performance of ns-3 or its models
  • Use of ns-3 in industry
  • Special applications of ns-3
  • Educational use of ns-3
  • Shorter papers that are otherwise within scope of the regular paper track

Papers about ns-3 use in industry are suggested to address these questions:

  • What specific R&D questions did you or do you want to answer by simulation?
  • Why and how did you choose ns-3 as the appropriate tool for your application?
  • What surprises did you find, in correctness/behavior? in implementation? in learning curve?
  • What are the remaining barriers to addressing fully your R&D questions?
  • What general capabilities would have made your work easier/faster?

Submission instructions

Authors should submit papers through EasyChair in PDF format, complying with ACM “sigconf” Proceedings format. Submitted papers must not have been submitted for review or published (partially or completely) elsewhere. All papers must be written in English.

Acceptance Criteria

Every paper will be peer reviewed by the technical program committee. Papers will be accepted based on the relevance, novelty, and impact of the contribution, as well as the quality of writing and presentation.

Authors presenting new ns-3 models, frameworks, integration setups, etc. are encouraged to include all traditional parts of a scientific paper: introduction, motivation, related work, assumptions, verification and validation, conclusions and references. As a general rule, papers that only document source code will be rejected.

Authors presenting networking research using ns-3 are encouraged to follow best simulation practices and focus particularly on the credibility and reproducibility of simulation results. We strongly encourage authors of all papers, demonstrations, and posters to include links to relevant source code and instructions on how to use it. This will make contributions more useful for the ns-3 community. If code has been submitted through the ns-3 merge request process, or published as a module in the ns-3 app store, please list the link(s), this will be considered a plus. Published, high-quality artificts will be a consideration in the Best Paper evaluation, and in the awarding of ACM artifacts badges (see below).

Please do not hesitate to contact the workshop chairs if you are uncertain whether your submission falls within the scope of the workshop.

Artifacts Evaluation

Accepted papers will be reviewed by an Artifacts Evaluation Committee for consideration of the awarding of ACM artifacts badges, according to the criteria listed by ACM.

For an example of a paper from WNS3 2022 that produced high-quality artifacts enabling the easy reproduction of all paper figures, please see the paper by Nicolas Rybowski and Olivier Bonaventure, Evaluating OSPF convergence with NS3-DCE. paper; video; slides

Another example of a paper from WNS3 2022 that provides full code including scripts and documentation to reproduce the plots is the paper by Hao Yin, Sumit Roy and Sian Jin, IEEE WLANs in 5 vs 6 GHz: A Comparative Study. paper; video; slides; code

Copyright Policy

Accepted papers will be published in the ACM Digital Library, which will require copyright transfer to ACM under their normal terms and conditions. In the spirit of open source, we encourage authors of published papers to exercise their right to publish author-prepared versions on their respective home page, on a publicly accessible server of their employer, or on a pre-print server. Upon request, we will provide links from the WNS3 program on the ns-3 web site to the author-prepared version.

Plagiarism Policy

We follow the ACM standards and conduct regarding plagiarism.

Reviewing Process Conflict of Interest Policy

Reviewers will follow the IEEE/ACM Transactions on Networking Conflict-of-Interest Guidelines. Authors are requested to identify potential conflicts-of-interest among the workshop’s technical program committee.

Demonstrations and Short Talks

In addition to the published paper track, we will organize an exhibition-style demonstration and short talks session. The aim is to foster interactive discussions on work-in-progress, new problem statements, ideas for future development related to ns-3, and display innovative prototypes.

A separate Call for Short Talks and Demos will be posted at a later date. Accepted short talk and demo abstracts will be published on the ns-3 web site. At least one author of each accepted demo/short talk must register and present the work at the workshop.


One Best Paper will be selected from the regular paper track by the TPC chairs and will be announced at the workshop.


Registration information will be posted at a later date. At least one author of each accepted paper must register and present the work at the workshop.
