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.

I need to send a message only to one vehicle that i want to choose. I am reading the available TraCIDemo11p and the cars are broadcasting the message to all cars. How can change that and make it send the message to only one care for example to car…

Determining when two vehicles are in contact(Veins, Omnet++)

In Veins/Omnet++ simulation, how can I determine when two vehicles are in range to exchange data? Suppose, I have three vehicles in a simulation (v1, v2, v3). During simulations these vehicles pass each other a few times. Now suppose v1 and v2…

Veins - Unexpected behavior with lost packets in certain vehicles

I'm working with the Veins framework over the OMNeT++ simulator and I'm facing a weird situation where certain few nodes lose all received packets. To put everybody in context, I'm simulating 100 nodes (4 flows of 25 nodes), all under coverage…

Exchange messages between nodes with a new map and without accidents

I executed the Veins example with the erlangen map and I put node[*0].veinsmobility.accidentCount = 0, I noticed, during simulation, that there was no exchange of messages between nodes which is logical. I have generated my .rou.xml, .poly.xml and…
