Can I use other version of OMNET++ and INET?

[krzycho2]

Hello. In Network Simulator OMNeT++ page (https://www.eclipse.org/mosaic/docs/simulators/network_simulator_omnetpp/) it's said that supported versions for OMNET++ and INET are 5.5 and 4.1. The current versions are 5.6.2 and 4.3.0 respectively. How can I use these versions in MOSAIC?

MOSAIC is coupled with OMNeT++ using a federate, which is basically a proxy which exchanges protobuf-messages between the OmnetppAmbassador which is integrated in MOSAIC. This federate is written in C++ and extends the official OMNeT++ code with the code to send/read those protobuf-messages, but also loads the OMNeT++ simulator, adds and configures nodes, sends V2X messages, and so on. This federate code is located in a separate repository and is only compatible with a specific version of OMNeT++ (currently 5.5).

What you need to do would be to adjust the code in this repository to get it to work with the latest version of OMNeT++, and you also might need to adjust our installation script (located here). You do not necessarily this script but you can build the federate by your own if you know what you're doing.
