$ns run

Procedures to execute the Simulation

1. Save the Script:

• The above TCL script must be saved to a file, for instance, wireless simulation.tcl.

2. Run the Script:

• Direct to the file which includes the script after opening a terminal.
• By the use of NS2 command, the script should be executed.

                   ns wireless_simulation.tcl

Examine the Results:

• A NAM file (out. Nam) and a trace file (out.tr) will be generated through simulation.
• To visualize the simulation, utilize the NAM (Network Animator) tool.
