Eclipse MOSAIC Essentials -
The Simulation Suite for Connected and Automated Mobility

Eclipse MOSAIC is a multi-scale simulation framework in the field of smart and connected mobility. It allows coupling simulators from various domains towards a comprehensive simulation tool. Data exchange and time management is implemented by the Runtime Infrastructure (RTI), which is the heart of MOSAIC. Simulation models are coupled to the RTI using HLA inspired interfaces; Each simulator is wrapped into a "Federate" object which is linked to an "Ambassador" which is directly coupled with the RTI. Currently, the following simulators are coupled with the MOSAIC RTI:

• MOSAIC Application (application simulation)
• Eclipse SUMO (traffic simulation)
• OMNeT++ (communication simulation)
• ns-3 (communication simulation)
• MOSAIC Cell Simulator (cellular communication simulation)
• MOSAIC Simple Network Simulator (communication simulation)
• MOSAIC Environment (environment and event simulation)
• MOSAIC Output Generator (evaluation and visualization)

The project is a Maven based multi-module project and has its child modules organized in three main categories:

• rti - MOSAIC RTI: modules providing the runtime infrastructure API and implementation
• lib - MOSAIC Libraries: mathematics, spatial, routing, utilities, communication models, and data exchange
• fed - MOSAIC Ambassadors/Federates: simulators and couplings which integrate simulation models to Eclipse MOSAIC

The Essential Edition of Eclipse MOSAIC

This repository contains the Essential edition of Eclipse MOSAIC, which includes the runtime infrastructure, the core libraries, and various implementations of simulators or couplings to existing ones. All features included in this version of Eclipse MOSAIC are sufficient for most use-cases in the field of smart and connected mobility. Additional simulators and assessment features are provided by Fraunhofer FOKUS on a commercial basis.

Related Repositories

• Eclipse SUMO is coupled directly using the TraCI interface. We recommend using the SUMO release 1.21.0.
• The coupling to ns-3 is realized by a federate implementation which can be found in our MOSAIC Addons repository. We currently support ns-3 version 3.36.1.
• The coupling to OMNeT++ is implemented in a very similar manner. The corresponding federate implementation can be found in our MOSAIC Addons repository. We currently support OMNeT++ version 5.5 in combination with the INET framework in version 4.1.
• We created the Berlin SUMO Traffic (BeST) scenario which provides 2.2 million vehicle trips in 24h for Berlin, Germany. The scenario is fully compatible with the latest release of MOSAIC.
• In our research, we currently use Eclipse MOSAIC and the BeST scenario to evaluate traffic state estimation algorithms. For that, we provide application models and tools for Traffic State Estimation compatible with MOSAIC.

Prerequisites

Important

In contrast to previous versions, Eclipse MOSAIC now requires at least Java 17 SDK.

For a successful build you need the following software to be installed:

• Maven 3.1.x or higher.
• Java 17, or 21 - We recommend using the Adoptium OpenJDK (aka Eclipse Temurin).
• SUMO 1.21.0 - Older versions > 1.2.0 are most probably supported, but not tested. The environment variable SUMO_HOME should be configured properly.

Build

Eclipse MOSAIC is a Java base project using Apache Maven for build and dependency management.

Once installed, you can build Eclipse MOSAIC using the following command:

mvn clean install

This command executes all tests as well. In order to skip test execution, the following command succeeds:

mvn install -DskipTests

After building, a MOSAIC bundle including a start script and all necessary configurations is located in the bundle\target directory.

After extracting this bundle to an arbitrary path, Eclipse MOSAIC can be executed using:

mosaic.sh -s HelloWorld
mosaic.bat -s HelloWorld 

IDE Setup

Apart from the aforementioned approach, the simulation can also be started in your IDE using the main method in org.eclipse.mosaic.starter.MosaicStarter. Please have a look at the setup page in the documentation here.
