How do you create 50 nodes in ns2?

To create 50 nodes in NS2 (Network Simulator 2), you can use the following Tcl script snippet:

<code class="language-tcl">set ns [new Simulator]
for {set i 0} {$i < 50} {incr i} { set node($i) [$ns node] }
</code>

This script initializes a new simulator instance and then creates 50 nodes in a loop, storing each node in an array called node. You can further configure these nodes as needed for your simulation.
