The ONE is a simulation environment that is capable of
- generating node movement using different movement models
- routing messages between nodes with various DTN routing algorithms and sender and receiver types
- visualizing both mobility and message passing in real time in its graphical user interface.
- ONE can import mobility data from real-world traces or other mobility generators. It can also produce a variety of reports from node movement to message passing and general statistics.
The ONE simulator was developed at Aalto University and is now maintained and extended in cooperation between Aalto University (Comnet) and Technische Universität München (Connected Mobility).
The ONE simulator has been developed in the SINDTN and CATDTN projects supported by Nokia Research Center (Finland), in the TEKES ICT-SHOK Future Internet and IoT-SHOK projects, Academy of Finland projects RESMAN and Picking Digital Pockets (PDP), European Community’s Seventh Framework Programme SCAMPI project, and supported by EIT ICT Labs.
The latest release:
Older versions of the ONE are available from the old ONE homepage.

For questions about the simulator you can subscribe to the ONE user community email list at our mailman.
This list is for discussion and announcements for the ONE simulator. The users of the ONE can report bugs, share experiences and code, and give hints to each other on this list. New releases of the ONE are also announced on this list.
However, we are planning to move to a new platform for Q&A in the near future. Stay tuned, the change will be announced at the mailing list.

Running (a really quick help)
Download the program. Compile it using your favourite IDE or
compile.bat (on Windows) or
compile.sh (on Linux or Mac OS X).
Start a simulation by typing in (Linux/Unix/OS X) terminal:
or (in Windows):
After a short while, the GUI should start and a simulation based on default settings should be up and running.
Every simulation run uses the settings from default_settings.txt, if one exists. You can give an additional configuration file(s) as a parameters to define new settings or override the ones defined in default settings. For example:
That would use the (included) snw_settings.txt settings configuration file and change the router for all nodes to Spray and Wait (default is “passive router”, i.e., no routing logic). See default_settings.txt for information about the different settings.
If you don’t wish to use the GUI, you can run simulations in batch mode using -b option. In batch mode you can also define the number of runs using different run indexes. For example:
./one.sh -b 22 example_settings/snw_comparison_settings.txt
That would run Spray and Wait comparison using 11 different message copy counts and with binary and normal mode. See Settings class’ javadoc for details about run indexing.
To create a local copy of the javadoc documentation, run the
create_docs.sh script in the doc folder.
See the project README for more information.
