[ns] Log Node movements (mail corrected)

[Hector Agustin Cozzetti]

Hello everybody!
I have a doubt about the log movements. I need the *coordinates* (x,y) of
nodes appear on the trace output (file .tr or file .nam). I have read in
some tutorials that I have to add the following procedure  in the tlc file:

*proc log-movement {} {

    global logtimer ns_ ns

    set ns $ns_
    source ../mobility/timer.tcl
    Class LogTimer -superclass Timer
    LogTimer instproc timeout {} {
        global opt node_;
        for {set i 0} {$i \< $opt(nn)} {incr i} {





            $node_($i) log-movement
        }
        $self sched 0.1
    }

    set logtimer [new LogTimer]
    $logtimer sched 0.1
}*

But, there's a problem, I don't know how to call it and use it. In my tlc
file i wrote that, but nothing happens. Could you help me, please? I links
where I took the information:
