[Hi Everyone] Ns3Visualizer – Qt-based PPDU Timeline & PHY/MAC Activity Visualization Tool for ns-3

[zhangkai]

Hello ns-3 community,

My name is Kevin Zhang, and I am an undergraduate student working on network simulation and visualization tools. I would like to share an open-source visualization tool I developed for ns-3 simulations: Ns3Visualizer.

Ns3Visualizer is a Qt-based GUI application designed to provide interactive, time-based visualization of PHY/MAC layer activities, especially PPDU-level events.

Key features:
• PPDU timeline visualization
• PHY/MAC transmission activity tracking
• Throughput curve plotting
• Interactive zoom and inspection
• Compatible with modern ns-3 versions

The goal of this tool is to improve post-simulation analysis and provide more intuitive insight into wireless protocol behavior at the PHY/MAC layer. It may also help users who are less familiar with the ns-3 source code better understand simulation behavior.

The project is open-source and available here:
https://github.com/z14212638-eng/Ns3-based-Visualization

Documentation and tutorials are included in the repository.

Feedback, suggestions, and potential collaboration are warmly welcome.

Best regards,
Kevin Zhang
