hi i am a new user in NS-2, i'm using version NS-2.34 based on windows xp.
i try simulate routing protocol ;example for ad-hoc simulation with AODV from
this website
http://read.pudn.com/downloads93/sourcecode/windows/comm/364468/aodv/wrls-aodv.tcl__.htm
i got error when run the simulation on cygwin, in the other hand i have checked
the warning that led me to example of tcl/wireless-mitf.tcl,
runs the simulations it works well but i tried to compare with what i did it's
quite different.

when run my works on ns-2.34
the error shows :
$ns wrlsl.tcl
num_nodes is set 5
warning: please use -channel as shown in tcl/wireless-mitf.tcl
syntax error in expression "$i $val(nn) ": extra tokens at end of expression
while executing
"for {set i 0 } {$i $val(nn) } { incr i } {
set node_($i) [$ns node]
}
(file "wrlsl.tcl" line 51)
i went through to line 51 but found nothing to change there
please help to get the result. i really need your help to understand well about
AODV
thank you very much
best
