A simple four-node point-to-point network can be created using the NS-3 network simulator. For this experiment, it is assumed that Node 1, Node 2, Node 3 and Node 4 are connected in a linear topology. Thus, Node 1 is connected to Node 2, Node 2 to Node 3, and Node 3 to Node 4. Each connection is a separate Point-to-Point (P2P) link. The IP address ranges 10.1.1.0/24, 10.1.2.0/24 and 10.1.3.0/24 are assigned to the three links respectively. The following NS-3 program can be used: ```cpp #include "ns3/core-module.h" #include "ns3/network-module.h" #include "ns3/internet-module.h" #include "ns3/point-to-point-module.h" #include "ns3/applications-module.h" using namespace ns3; int main() { NodeContainer nodes; nodes.Create(4); PointToPointHelper p2p; p2p.SetDeviceAttribute("DataRate", StringValue("5Mbps")); p2p.SetChannelAttribute("Delay", StringValue("2ms")); NetDeviceContainer d1 = p2p.Install(nodes.Get(0), nodes.Get(1)); NetDeviceContainer d2 = p2p.Install(nodes.Get(1), nodes.Get(2)); NetDeviceContainer d3
