This is multi-threaded version of INET Framework. Our implementation is able to reduce the simulation time, ensuring seamless integration with the existing scenarios of a user. Our code is based on the legacy INET Framework and it has been modified accordingly. The INET Framework is an open-source suite for wired, wireless, and mobile networks.

Two different versions of the multithreaded INET framework are provided. The first one is based on ver. 3.6.4-394571f (multithreaded_inet_3.6.4). The second one, is based on ver. 4.0-576b2dc (multithreaded_inet_4.0). Both versions provide the same functionality described above. Either one can be chosen based on the versions of OMNeT++, Veins, and SUMO that will be used.

For our research purposes, we modified the functions below:

• visitObject in the PhysicalEnvironment class.
• visit in the DielectricObstacleLoss class.

We also introduced the notion of the distanceBoundary under within the ScalarAnalogueModel class.
For further details about our modifications, please refer to our paper https://github.com/v2x-dev/multithread-inet/blob/master/ieeevnc2018.pdf and our poster https://github.com/v2x-dev/multithread-inet/blob/master/poster_ieeevnc2018.pdf.

The code is compatible with Linux (Ubuntu 16.04 LTS) and OS X 10.12 and 10.13. The version 3.6.4, is compatible with OMNeT++ 5.2.1 and Veins 4.6. The SUMO Traffic Generator (ver. 0.30.0) is required to generate the vehicle routes. The version 4.0 is compatible with OMNeT++ 5.4.1 and Veins 5 alpha 1. The SUMO ver. 1.0.1 is required for that case. All the above tools should be pre-installed. Please refer to the links below for detailed guides of how to install them.

For information about how to use Veins with INET and OMNeT++, please refer to Veins_INET sub-module (website).

1. Our Multi-threaded INET project should be imported in OMNeT++. For more information, please refer to OMNeT++ Documententation.
   • Ensure that no other version of the INET Framework is opened in OMNeT++.
2. The Multi-threaded INET project should be later compiled (Build Project in OMNeT++).
3. Veins and Veins_INET projects should be imported in OMNeT++ and compiled as well.
4. At the omnetpp.ini, please add the following lines:

Scenario.physicalEnvironment.numberOfThreads = 4
Scenario.radioMedium.analogModel.distanceBoundary = 1000

5. The Scenario is the name of the network to be simulated in OMNeT++. The numberOfThreads can be modified accordingly to the machine used (please refer to our paper for more information and the difference in the performance introduced). Finally, the distanceBoundary can be modified with regard the scenario and the granularity required from the user.
