The CSMA model in network simulator is considered as the fundamental model based on the Ethernet like network. It is assistive for the carrier sense functions and permits the multiple accesses to share the medium.
Simulation Code Using CSMA
Here, we have highlighted some sample simulation codes using CDMA along with its functions in the following.
- Router configuration
multicastRouter = c.Get (2);
inputIf = nd0.Get (2);
outputDevices.Add (nd1.Get (0));
multicast.AddMulticastRoute (multicastRouter, multicastSource, multicastGroup, inputIf, outputDevices);
sender = c.Get (0);
senderIf = nd0.Get (0);
multicast.SetDefaultMulticastRoute (sender, senderIf);
- CSMA based node configuration
NS_LOG_INFO ("Build Topology.");
csma.SetChannelAttribute ("DataRate", DataRateValue (DataRate (5000000)));
csma.SetChannelAttribute ("Delay", TimeValue (MilliSeconds (2)));
NetDeviceContainer nd0 = csma.Install (c0);
NetDeviceContainer nd1 = csma.Install (c1);
- Include header file
Execute CSMA Code in Ns3
Following that, we can implement the CSMA code in ns3 type and that commands are implemented in the terminal and the results are demonstrated below.
sudo ./waf --run CSMASimulationCode --vis
Then, we have highlighted the result that is acquired through the implementation of the above mentioned commands.
We are all set to provide the appropriate research guidance for the scholars for reach us and aid more.
