[ns] queue resume/ block, unblock, Scheduleer; Event UID not valid
Hello ns users, I have problems that if I have no enqued packets, I can not make the packet being dequed out although the output link is empty and there are some packets in the queue. Actually it does not make sense; however, I believe it's the problem as some people have discussed (I copied the link down here). http://mailman.isi.edu/pipermail/ns-users/2002-January/020180.html Some people suggests that " You can add an entry in the queue's command() function that calls resume(). Then you can resume your queue in $ns at 2.0 "$q_na_nb blocked_ false" $ns at 2.0 "$q_na_nb set blocked_ false" $ns at 2.0 "$q_na_nb resume" It seems that by debugging, the packets are dequed; however, there is an error said, "Scheduleer; Event UID not valid!". I wonder if there is anyone have this kind of problem? Problem: error queue command: Solution: make clean and make again http://mailman.isi.edu/pipermail/ns-users/2002-March/020820.html Problem: after make again, Scheduler: Event UID not valid Solutioin: don't know yet ? http://mailman.isi.edu/pipermail/ns-users/2002-January/020050.html _ Interest Rates near 39yr lows! $430,000 Mortgage for $1,399/mo - Calculate new payment http://www.lowermybills.com/lre/index.jsp?sourceid=lmb-9632-18466&moid=7581

My previous mail doesn't include error messages. I re-send mail to you. Please help for following error messages.

Re: [ns] How send only one bit?
Hi, I need send only 1 bit (not byte). Anybody knows how I can send 1 bit, 2 bits or 3 bits? The field packetSize in the class Agent set the size of the packets in bytes, mas I need only bits. I need that the ns calcule the cost to send only one bit, not one byte. Anybody can help me? Gustavo, can you? Thanks! Merci! __ Fale com seus amigos de graça com o novo Yahoo!

[ns] I neeh help for my script with MW-node patch
Hi ns-users,
I have installed in ns-2.30 patch MW-node,
http://www.q2s.ntnu.no/~paquerea/ns.html
through my script, would purely like to simulate a net wireless, where
presents of Access Point (2) and the mobile nodes(3). Access Point
communicate between them through the standard 802.11a, while the mobile
nodes only communicate cross Access Point with the standard 802.11b/gm.
Therefore Access Point need 2 interfaces with different settings (
802.11a, 802.11b/g ) using pach and the commands I have found in the
manual tried to set up all these elements in my script:
