The project coordinates a few summer coding programs in which student developers are paired with mentors to produce code over the summer.

Google Summer of Code 2025

The ns-3 project is a mentoring organization for GSoC 2025. If you are interested to get started, the best way is to read the project contributing guide and start to interact with the mentors listed on the project ideas page. The 'GSoC 2025' thread on ns-3's Zulip chat is also a good place to ask questions. You can also interact with maintainers in the issue/merge request trackers or on Zulip chat.

Google Summer of Code 2024

The organizational admins were Tommaso Pecorella, Mohit Tahiliani, and Tom Henderson.

We had three successful student projects, summarized on the pages linked below:

Google Summer of Code 2023

The organizational admins were Tommaso Pecorella, Mohit Tahiliani, and Tom Henderson.

We had three successful student projects for 2023; you can read their final reports below:

Google Summer of Code 2022

The organizational admins were Tommaso Pecorella, Mohit Tahiliani, and Tom Henderson.

Two contributors completed projects with ns-3 in the 2022 Google Summer of Code.

One additional project was started but did not progress past the midterm evaluation:

• Akash Mondal, TCP maximum segment size (MSS) improvements, mentored by Mohit Tahiliani, Bhaskar Kataria, and Vivek Jain

We received seven proposals, which were evaluated by a committee that includes most of the mentors listed on the Project Ideas page. For future reference, below is our ideas page and contributor's guide.

ns-3 Summer of Code 2022

ns-3 Summer of Code (NSoC) is a program that runs in parallel to Google Summer of Code. Unlike GSoC, it is not funded, but we aim to operate it similarly to GSoC.

• Chandrakant Jena, Ping and Ping6 Enhancements for ns-3: project wiki page mentored by Tommaso Pecorella and Tom Henderson

The project by Chandrakant was completed successfully in December 2022, with six commits made to ns-3-dev starting with commit da107e04. The project added a new Ping application, helper class, example program, unit test, and documentation.

Google Summer of Code 2021

Three students successfully completed projects in Google Summer of Code 2021.

• Parth Pratim Chatterjee, Direct Code Execution Modernization: project wiki page -- Final report
• Ameya Deshpande, IPv6 Nix-Vector Routing: project wiki page -- Final report
• Akshit Patel, Add logging support to Simulation Execution Manager (SEM): project wiki page -- Final report

For reference, below were the 2021 project ideas and the 2021 student guide:

ns-3 Summer of Code 2021

ns-3 Summer of Code (NSoC) is a program that runs in parallel to Google Summer of Code. Unlike GSoC, it is not funded, but we aim to operate it similarly to GSoC. The commitments are similar; students and mentors are expected to define and work towards a mergeable project goal by the end of the summer. The program is offered to 'honorable mention' GSoC proposals (i.e., proposals that we would have selected had we received more student slots from Google) and for other reasons such as a contributor's ineligibility for GSoC.

• Nitya Chandra, Enable IPv6 support for ad-hoc routing protocols in ns-3: project wiki page Note: project did not complete

Google Summer of Code 2020

Four students successfully completed Google Summer of Code 2020 projects:

• Shivamani Patil, App Store Improvements: final report, project wiki page
• Ananthakrishan S, NetDevice up/down consistency and event chain: final report, project wiki page
• Bhaskar Kataria, SCE AQMs and TCP along with CNQ-CodelAF and LFQ final report, project wiki page
• Deepak K, TCP Prague model for ns-3, final report, project wiki page

For reference, below were the 2020 project ideas and the 2020 student guide:

• Project Ideas Page

ns-3 Summer of Code 2020

These projects are unfunded but are mentored in a manner similar to GSoC, at a lesser pace than the 12-week GSoC program.

• Muhammad Iqbal Rochman, Wi-Fi PHY Restructure Note: This project successfully completed.
• Harsha Sharma, L4S evaluation framework Note: This project continued through fall 2020 but did not yet merge.
• Rahul Bothra, Routing for community wireless networks Note: Project discontinued in August 2020.
