[Click] nsclick wireless traces etc

[David Bath]

Hey List, 

Sorry, me again.  I've done a bit of ns debugging, and in cmu-trace.cc
(which seems to handle the tracing) there's a function CMUTrace::command
which is responsible for setting the newtrace variable.

CMUTrace::command(int argc, const char*const* argv) {

        if(argc == 3) {
                if(strcmp(argv[1], "node") == 0) {
                        node_ = (MobileNode*)
TclObject::lookup(argv[2]);
                        if(node_ == 0)
                                return TCL_ERROR;
                        return TCL_OK;
                }
		if (strcmp(argv[1], "newtrace") == 0) {
			newtrace_ = atoi(argv[2]);
		        return TCL_OK;
		}
        }
	return Trace::command(argc, argv);
}

However, although it's being called, argv[1] is always "namattach" or
"attach" or "target", so the newtrace_ variable is never set.

Any thoughts would be much appreciated!

Best Regards,

Dave

Hi List,

A small update on this.  I've been working today to try and find a more
precise set of conditions.  It seems I can't produce a new trace format
if I use the a mobile node of type Click.

As suggested in the nsclick papers, I am using 

Simulator set node_factory_ Node/MobileNode/ClickNode

As soon as I do that, the use-newtrace directive appears to be being
ignored.

I can't really find out a sensible combination of options to get more
precise than this - purely that something about using a ClickNode
prohibits traces in the new format.

Any thoughts very gratefully received!

Best Regards,

Dave

Hi List,

This may be the wrong place, but the nsclick lists appear to have moved
and I haven't managed to track them down.  Please feel free to redirect
me if this is best answered somewhere else.

I've been working with ns(2.3) and latest[checked out a few days ago]
click(cvs).

As far as I can tell, basic features are working fine.  However, I'm
having some problems with the trace format.  

I've tried the well documented: 

set tracefd [open "<filename>" w]
$ns_ use-newtrace
$ns_ trace-all $tracefd

But the trace file comes out in the old format still.

I also don't quite understand how the ClickNode factory works.  Is the
standard mobilenode creation process triggered?  

i.e. is $ns_ node-config .... etc valid syntax? (I ask because setting
movementTrace ON like this seems to make no difference).

Any help would be gratefully received.  I seem to have run dry on web
resources on this issue (at least, I am supposing it's an nsclick thing
as the standard instructions for ns don't seem to work).

Cheers,
