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
