Re: [ns] Problems running a simple tcl script for wireless nodes.




Dear Richa,
              You have missed two things there in your script.
    1.> $ns_ node-config - addressType hierarchical
        
	There should not any gap between the options. It should be:
      $ns_ node-config -addressType hierarchical 
   2. second one is that one option is having  
       -routertrace   OFF  instead of -routerTrace OFF
