CoRE Simulation Models for Real-time Networks

Version 3 (modified by buschmann, 3 years ago) (diff)



FiCo4OMNeT stands for „Fieldbus Communication For OMNeT“. At this point the model consists oft two communication technologies – CAN and FlexRay. Both of them are implemented based on the according specification with some adaptions to fit in the simulation environmnet.

Features CAN

It is possible to create networks with traffic consisting of Data-, Remote- and Error-Frames. In most cases the traffic is cyclic, hence it is possible to define a clock drift to bring some variation to the transmit and receive times.

Features FlexRay

Each node can transmit messages in the assigned slots within the static and the dynamic segment. Based on the configuration the frame is transmitted on channel A, channel B or on both. Every member of the network has an own clock. Based on the configuration each clock has an inaccuracy. The implemented synchronisation compensates theses drifts.


FiCo4OMNeT was first introduced as FlexRay simulation model at the 6th International Workshop on OMNeT++ (2013) along with the 6th International ICST Conference on Simulation Tools and Techniques (2013). You can find the publication and slides here.

To merge the simulation models of CAN and FlexRay significant changes were necessary. The result of this merging process is the FieldBus for OMNeT++ Simulation model (FiCo4OMNeT)
