Steps to Create Ns2 Simulation

Hereby, we have highlighted the steps that have been deployed to create the simulation based on network simulator 2.

  • Initially, define the network topology which includes
  • Router queuing rules
  • Links
  • Nodes
  • Then, we have to create some TCP or UDP connections using the agents and they are attached to the nodes
  • Following that, we have to create some applications such as
  • Telnet to intermittent random packet generation
  • FTP for bulk transfer
  • Lastly, start the simulation
