How do I create a node in ns2?

Creating wireless nodes is also achieved using the ns_ node command: set ns_ [new Simulator] ;# Create a NS simulator object set n1 [ns_ node] ;# Create a WIRELESS node !!! However: BEFORE creating a wireless node you MUST first select (configure) the node configuration parameters to "become" a wireless node.
