Eclipse MOSAIC (formerly VSimRTI) is our co-simulation framework for developing and assessing mobility applications.
It's a Java based middleware and model library which is open-source and distributed under the
Eclipse Public License.
Below you find a pre-compiled bundle of the latest release version. Furthermore, you can find the
source code and contribute on our GitHub Repository.
More information about Eclipse MOSAIC, including detailed documentation and various tutorials,
can be found on the eclipse.dev/mosaic project webpage.
Further commercial downloads, e.g. of MOSAIC Extended and additional tools and simulators, can be found in the Extended Downloads section. To get access, please contact us at .

MOSAIC: Allow configuration of a connection id as departure position of a vehicle. (new)
MOSAIC: Refactored and unified matrix implementations in mosaic-utils. (bugfix)
Traffic sim: Enhanced interface to SUMO to use context subscriptions in certain situations. (new)
Traffic sim: Now supports SUMO 1.13.0 (new)
Traffic sim: Fixed wrong position problem of parked vehicles. (bugfix)
MOSAIC Extended: Introduced new physics engine in PHABMACS based on PhysX (Extended). (new)
Additional Notes
If you want to use the communication simulators ns-3 or OMNeT++, you can rely on the provided installation scripts (for native installation) or the Dockerfile (for Docker-installation), located in the bin/fed folder. Please have a look in the user manual. For native installation, it is recommended to use Linux based systems for ns-3 and OMNeT++.
In order to run MOSAIC with the traffic simulator SUMO it is necessary to add the sumo-bin-folder to your PATH variable.
