Hi, I'm simulating a simple wireless (802.11b Basic Mode) experiment. At the end of the simulation, I get this error:
"Scheduler: Event UID not valid!" I understand that the message is being initiated from /ns/common/scheduler.cc file line 93 only because the UID of an event is positive. In other words, an event with positive UID cannot be scheduled again. Now, I'm using a timer to introduce a fixed delay for each packet -either control or data packet- passing through the interface layer. When I introduce 1 to 39us of delay to my system, the simulation works perfectly and as expected (i.e. there is a fixed delay for the transmission of each packet reflected into my trace file). However, when I increase this delay to 40us and above, then run the simulation I get the above error. I have adjusted the timeouts in the ns/mac/mac-802_11.cc as well so that my packets are not all dropped. Please let me know if you have any ideas or thoughts about this. Where do you think I should look at first? What could the problem be? Thanks, Bahman _________________________________________________________________ Txt a lot?
