Mainly, network simulator 3 is designed for the integration of testbeds and virtual machine environments based on networking through the utilization of ns3::RealTimeSimulatorImpl.
Consequently, we have to configure the real time simulator based on network simulator 3 through the execution of the below mentioned commands in the terminal.
cd /home/research/ns-allinone-3.37/ns-3.37
sudo ./ns3 configure

Following that, we have to execute the real time simulator main file in network simulator 3 through the implementation of the below mentioned commands in the terminal.
cd /home/research/ns-allinone-3.37/ns-3.37
sudo ./ns3 --run realtime-udp-echo
