What's this

OMNeT++ is an extensible, modular, component-based C++ simulation library and framework, primarily for building network simulators.

However OMNeT++ does not include simulation model to simulate automotive control networks. 

Here, we have distributed source code of a simulation model for Controller Area Network (CAN) for OMNeT++ as an open-source.

Anyone can download the source code at Github and simulate the CAN network. However, the distributed source code is a beta version which may include some bugs.

We have also distributed a CAN-Ethernet GW model as an experimental version. It can be found Github.

Features

• A simulation model for CAN (Controller Area Network) for OMNeT++. This is the only one found in the world so far.

• A simulation model for CAN message router is included. By using this model, CAN-CAN gateway can be simulated easily.

• Error frame of the CAN protocol is not supported in the current version. It may be supported if there are any requests.

Environment

• OMNeT++ 4.4.1 or later (We confirmed on 4.4.1 and 4.6. Unfortunately, 5.x are not supported.)

• INET-Framework 2.3.0 or 2.5 (We found some errors when compiling with INET 2.6 or 3.x.) 

Installation Instructions

1. Download and Install OMNeT++ and INET-Framework in your computer (usually ~/program/). If you install them for the first time, please refer to their install guides.

 2. Extract the downloaded zip file and copy all source files into your inet directory (usually ~/program/omnetpp-4.4.1/inet/) as follows.

• 0.1.0/src/* -> ~/program/omnetpp-4.4.1/inet/src/

• 0.1.0/example/* -> ~/program/omnetpp-4.4.1/inet/example/

$ cp -r 0.1.0/src/* ~/program/omnetpp-4.4.1/inet/src

$ cp -r 0.1.0/example/* ~/program/omnetpp-4.4.1/inet/example/

3. Change to the root directory(e.g. ~/program/omnetpp-4.4.1) of OMNeT++.

$ cd ~/program/omnetpp-4.4.1

$ . setenv

4. This should generate the makefiles for you automatically.

$ ./configure

5. Type "make" to build the CAN executable.

$ cd inet

$ make clean

$ make makefiles

$ make

6. We implemented the following examples for CAN. These examples are located in omnetpp-4.4.1/inet/examples/can/. You can run specific examples by changing into the example's directory and executing "./run". If the run file has not permission of execution, type "chmod +x run".
