VEINS OMNeT++ SIMULATION

VEINS OMNeT++ is a framework which runs for vehicular network simulations.VEINS utilizes TCP Conncetion and python scripts for enabling SUMO framework which acts as a model in OMNeT++ Simulation Framework.

Characteristics of veins:

• Consists of two distinct simulator OMNET++ and SUMO.
• OMNET++ used for network simulation.
• SUMO for traffic simulation.
• To perform IVC simulation, both simulators are running in parallel, connected via a TCP socket
• Standardized as the TraCl.
• Nodes can then interact with the running road traffic simulation
• This allows bi-directionality-coupled simulation of road traffic and network traffic.
