Introduction

The global internet of vehicles market is growing rapidly, it is estimated to significantly increase its value by the next few years. Vehicular Ad hoc Networks (VANETs) have a central role in the development of Intelligent Transportation systems since vehicles can communicate with each other.

The vehicular communication architecture in NetSim is based on a combination of the IEEE 1609 standard and IEEE 802.11p standard. 802.11p standard defines PHY and MAC layers while upper layers are defined by IEEE1609.

The 5G library is based on Rel 15 / 3GPP 38. xxx series. 5G provides low latency communication and offers high data rate improving V2I (Vehicle to Infrastructure) connections

This article proposes a model integrating 5G for vehicular ad-hoc network management in NetSim.

Infographic:

Combination of VANET and 5G,

NetSim Scenario:

In this example, we are creating a scenario that is equivalent to the topology shown below. The flow of traffic is Vehicle-> RSU->Router->UPF->gNB->UE.

Network Configuration:

Application Configuration:

Static Route Configuration:

Static routes were configured from vehicle to Router since RSU doesn’t have any routing protocol to communicate with the router.

 Configuration File Structure:

Device Configuration: This section of the configuration file contains all the device properties used for this example

Connection Configuration: This section of the configuration file contains all the connection properties from one device to another as shown in the scenario.

Application Configuration: This section of the configuration file contains information about the application properties. i.e., in this example its CBR Application from Vehicle to UE.

Performing Simulation via command-line interface:

NetSim GUI does not allow combining the VANET and 5G toolboxes. Therefore, this combining is done via the configuration file. Once the configuration file is set up correctly, the simulation is then run via CLI.

Explanation on How to Run NetSim via CLI is explained in NetSim User Manual – Chapter 7 Running Simulation via Command Line Interface Section – 7.1.

Firstly, import the configuration file (attached) to NetSim. Explanation on how to import configuration files is given in User Manual Chapter 4 Workspace and Experiment section 4.10. 

Once you import the experiment you can perform the simulation via CLI.

Analyzing results and viewing NetSim animation:

Both Results Dashboard and Animation Window (if enabled in the configuration file) can be opened via NetSim UI after simulating the scenario via CLI.

All the files related to Results and Animation will be generated in the folder where configuration.netsim was simulated.

For opening Result Dashboard open command prompt in NetSim Installation directory and run command that given below,

NetSimMetrics.exe %appdata%\NetSim\std_13.1

After opening Result Dashboard, open Animation window by running command that given below,

NetSimAnimation.exe %appdata%\NetSim\std_13.1
