This page is an entry point to the ns-3 documentation maintained by the project (other tutorials exist on external blogs and on YouTube but are not typically listed here).
Documentation is available for the current release, older releases, and also our development tree.
- Tutorial: The tutorial for our latest release is available in HTML and PDF versions.
- Installation: We recently added a new installation guide, in HTML and PDF versions.
- Videos: The ns-3 Consortium has offered training and tutorial sessions at its annual meeting, and recorded videos from prior sessions can be found from this training page. Note that due to the pandemic, in-person training sessions have not been offered since 2019. For some additional recorded sessions, please see also the videos page.
- Mailing lists: We have several mailing lists, but in particular, the ns-3-users Google Group forum, answers many questions from people trying to get started.
- Chat: ns-3 discussions also take place in a Zulip chatroom.
Most users will need to write new simulation scripts and possibly modify or extend the ns-3 libraries to conduct their work. The three main resources for this are our reference manual, model library documentation, and our Doxygen.
- We maintain a reference manual on the ns-3 core, and a separate model library documentation set, also in several formats for our latest release.
- All of our APIs are documented using Doxygen
- The ns-3 coding style documentation is maintained on this site.
Some technical reports about the ns-3 models are listed below.
- Technical report on ns-3 IEEE 802.11ax models Note: ns-3 802.11ax code discussed in this report is in preparation for future public release.
- Validation of Wi-Fi DCF in saturation
- Validation of Wi-Fi 802.11n error model
- Validation of Wi-Fi OFDM error model
- Validation of Wi-Fi 802.11b error model
- Direct Code Execution: Documentation on the ns-3 Direct Code Execution environment is also linked from this site.
- Netanim: A network animator for ns-3.
- Bake: The package management tool for advanced ns-3 builds.
