The NS3 project analyses mobile ad hoc networks (MANETs) by varying node count and routing protocols. Using NS3, it evaluates packet delivery rate, throughput, and packet loss. Users input node count and routing protocol (AODV, DSDV, or OLSR) for the simulation.

I went to the ‘ns-3.29/src/traffic-control/model’ directory and opened the ‘traffic-control-layer.cc’ file. I commented out lines 209-211, which then allowed me to change the existing ‘DropTail’ queue to a FIFO queue.

which lines did you comment? Can you paste them here?

U can try to uninstall the existing queue before install a root queue and it will work:

TrafficControlHelper tch;
tch.Uninstall(devices);
tch.SetRootQueueDisc("ns3::FifoQueueDisc");
tch.Install(devices);
