Questions tagged [veins]

Veins is an open source framework for running vehicular network simulations.

Veins is an open source framework for running vehicular network simulations. It is based on two well-established simulators: OMNeT++, an event-based network simulator, and SUMO, a road traffic simulator. It extends these to offer a comprehensive suite of models for IVC simulation. See the official website for further information.

Is there any DCC algorithm implemented in Veins?

I learned from the Veins website that Veins relies on IEEE 802.11p and 1609.4 which does not mandate a DCC mechanism. I am wondering if any DCC algorithm is still implemented in Veins except using 3rd party models?
