Re: Problem : Running NS

[Padmaparna Haldar <haldar@ISI.EDU>]

Hi,
  you need to create an instance of the class Simulator. At the ns prompt
say,

% set ns [new Simulator] 
% set n1 [$ns node] /* then setting up a node */
and so on..

take a look at the example files under ns/tcl/ex
you may want to start off with simple.tcl in that same directory.

Padma.
