Figure 4‑6: List of scenarios for the example of Vehicles and RSUs
NetSim VANETs module supports V2V and V2I communication. RSU's are now part of the GUI environment and can be dropped in addition to importing Vehicles from a SUMO configuration. Traffic can be configured between vehicles (V2V) and between vehicles and RSU’s (V2I).
This scenario involves a simple road traffic network scenario as shown below:
Figure 4‑7: Network topology in Sumo
An equivalent network is created in NetSim by importing the SUMO configuration file as shown below:
Figure 4‑8: Network set up for scenario involving vehicles and RSUs for v2v and v2i communication
After importing the SUMO configuration file in NetSim, RSU’s were added at junctions. In NetSim the TCP/IP stack parameters of the devices are configured along with network traffic between vehicles and between vehicles and RSU’s.
After running the simulation, NetSim Animation can be used to visualize packet flow and vehicle mobility along with packet information. Time varying throughput plot can be opened from the Results window.

Simulation results dashboard provides the performance metrics of protocols running in different layers of the network stack of the devices.
