Re: [ns] I have a problem in simulation .... while the compilation is okay
I reckon a new event ID is assigned every time you schedule an event. You
can create a new packet and have it sent down in Mac.

As you see in my code; that i create new packet in [void

after debugging: the problem is stopped inside sendDown():
if(!abstract_)
s.schedule(hRes_, intr_, txt);
when I tracked the code inside the scheduler.cc; the progressing stops
in:
Scheduler::schedule(Handler* h, Event* e, double delay)

if (e-uid_ 0) {
printf(Scheduler: Event UID not valid!\n\n);
abort();
}

Thus, can you tell me how can I create new packet inside MAC layer with
new
valid Event UID.
your help is highly appreciated

One possible reason to the Event UID not valid! problem is that the
event has been scheduled twice. You can print the relevant event in the
scheduler.cc, and see if that helps.
