Creating nodes in NS

---

---

• Creating Nodes in NS
  • The Node class in NS is used to simulate routers

  • The node must be created through the special method node defined in the Simulator class.

    The following expression will return a Node object in NS that you use to simulate ONE router:

    set ns [new Simulator] set n0 [$ns node]

    ---

  • If you need to create a lot of routers, use a for loop.

    Example: create Nodes n(0), n(1), ..., n(9):

    for {set i 0} {$i < 10} {incr i} { set n($i) [$ns node] }
