LSNS is an open-source network simulator based on ONE simulator, it is designed to better support simulations under large-scale satellite networks and provide friendly interactive GUI.


LSNS is developed and maintained by Infonet, USTC.

Since the program is sponsored, LSNS will not be updated very often on Github, some functions will only be avaiable in our group. If you have further questions, you are welcome to send your questions to the following e-mail: [email protected] and [email protected].

We develop LSNS simulator based on ONE simulator, you can use the architecture built by LSNS and develop your own function by using IDE such as Eclipse or Intellij idea (preferred). You can find the main function in "ONE-Extended-Simulator/core/DTNSim.java". Currently, we offer two GUI options:

1. To enable default 2D GUI (developed by ONE simulator), setting "userSetting.GUI = false" in "default_settings.txt"

2. To 3D GUI which can display the orbit of satellites, setting "userSetting.GUI = true" in "default_settings.txt"

You can download our code and import it as a new Java project in Eclipse or Intellij idea:

For Eclipse: Please refer to website

For Intellij idea: Please refer to website (choose "Create project from existing sources" and add library in "ONE-Extended-Simulator/lib" folder)

LSNS will read "ONE-Extended-Simulator/default_settings.txt" file as its simulation setting, you can change "default_settings.txt" to realize your own simulation. Original setting file in ONE simulator is located in "ONE-Extended-Simulator/default_settings_ONE_backup.txt", you can compare these two files and find the difference of settings between ONE and LSNS.

We are trying to improve our code and make a stable version, but you can still build the program and have your own executable Jar file based on our current version.

If you have more questions about the mechanism of the simulator, you can also refer to Q&A of ONE simulator and other specific blogs like Spark & Shine.
