The release manager is Tom Henderson. Please contact if you would like to participate in any way in preparing the ns-3.24 release, or helping to manage a future release.
- If you are interested in testing a particular feature that is planned for ns-3.24, see the section on this page for testing repos.
- If you are interested in helping with a code review of a specific feature that you'd like to see in ns-3.24, please leave your comments on the code review pertaining to the feature of interest.
- If you are interested to see that a specific bug be fixed, please email ns-developers mailing list, or the release manager. You will probably be asked to help with creating a patch or testing an existing patch for that bug, if so.

- 7 New features
1) Python 3 support for at least the basic waf and test.py operations; see the Python3 page.
2) continue the transition to a more modular build system. While a change away from the Waf build system is not planned for ns-3.24, one goal is to start to allow modules outside the core of ns-3 to be maintained in separate places, and integrated using the 'bake' tool (rather than merge everything into ns-3-dev).
- A proposal can be found at ns-3.22-build
3) finally try to implement Object Start/Stop; Vedran is working on a patch
4) Add new features as they become ready. In particular, finish inclusion of previous summer project code, including SOCIS 2013 and 2014 code (Bundle Protocol, TCP satellite extensions), Google Summer of Code (MLDv2, AQM queues FqCoDel and SfqCoDel), and 2014 mentored projects (Mobility Service Interface, and Python 3 support).
Release and development schedule
ns-3.24 is planned for August 2015; exact date TBD. ns-3 makes roughly three releases per year (Dec/Jan, Apr/May, and Aug/Sept timeframes).
This means that we ought to get most new features and major changes into the simulator by late July.
More detailed scheduling is TBD once the release date is set. In general:
- one or more release candidates will be posted in the week prior to the actual release
- new features should be merged several weeks in advance of the release date
Feature and patch review status
This table is meant to put review items for merge to ns-3-dev on a schedule. Maintainers of a module can commit changes as they see fit (i.e. without going through review for everything), but for proposals that seek or need a review, we should try to allow a default of 1 week review time before the release manager or a maintainer commits the change.

Please also have a look at two MPTCP proposals:
ns-3.24 will be packaged as a source tarball as before: ns-allinone-3.24.tar.bz2.
Other details (other formats, etc.) are for further study.
A patch from ns-3.23 to ns-3.24 will also be posted.
Whether ns-3.24 is prepared in other packaging (e.g. Debian) would require a volunteer to prepare this.
Whether ns-3.24 will be distributed also as a Docker container would require a volunteer to prepare this.
We usually try to keep pace with the latest popular versions of Linux, OS X, and FreeBSD. For the ns-3.24 release, we plan to support the following systems and compilers:
Some repositories, based on a recent copy of ns-3-dev, will be available for testing specific features.
Mobility Service Interface
Tiago Cerqueria has posted some code that uses Google Maps and Directions API to fetch waypoints for the ns-3 waypoint mobility model, corresponding to real-world routes provided by the service. There is a testing repository available for this code (the patchset in https://codereview.appspot.com/176430044/ is too large to download from Rietveld). To test, one must obtain an API key from Google, as described in the code review issue. One must also have installed GeographicLib, xerces-cpp, libcurl, and libdl.
hg clone http://code.nsnam.org/ns-3-dev cd ns-3-dev/src hg clone http://code.nsnam.org/tomh/mobility-service-interface cd mobility-service-interface mkdir conf # copy your API key to this conf directory as described here https://codereview.appspot.com/176430044/ cd ../../ ./waf configure ...
Developers are working or planning to work on the following new features for ns-3.24.
Note: there is no guarantee that the features will be finished by the end of the release cycle, so check back for progress/status.
Energy Enhancements (Cristiano Tapparello)
Cristiano plans several additions:
- New models for energy sources, converters, predictors, and sensor models (code to be posted soon)
- LithiumIonEnergySource helper
- RVBatteryModel bug fixes
- LEAR extensions https://codereview.appspot.com/96130043/
Status: Tomasz is working on addressing the review comments (no update recently)
Status: Still undergoing code review revisions.
Enhancements to data collection framework are planned to enable more flexible configuration of time series, time avearge, and asynchronous event plotting (Li Li, Felipe Perrone, Tom Henderson).
- Status: Development repo is found at http://code.nsnam.org/safe/ns-3.22-dcf; code review planned for week of June 15.
- Some of the TCP variants for satellite networks (Natale Patriciello) will be merged soon
- Note: Natale suggested that TCP Hybla and HighSpeed may be the first to be merged.
- RttEstimator improvements (Natale Patriciello)
- Resolve bug 1412 RttEstimator to network module
Software maintenance issues
- Time arithmetic consistency
- Wstrict-overflow and gcc-4.9 (Tom Henderson and Peter Barnes)
- Remove unnecessary dependency on Application module in other modules (1941) Tommaso Pecorella
- Cleanup of remaining modules unnecessarily dependent on applications (aodv, mesh, olsr, lte)
Status: No change on the above lately.
