[ns] LossMoniitor: npkts
Hi, I use the command: set RCVD [$sink set npkts_] to know how many packets have been received by ALL node. I'd like to know how many packet EVERY node or a group node send. Should I modify the implementation of Agent? Thanks _ Tutto il mondo MSN a portata di clic! http://toolbar.msn.com/overview.aspx?loc=it-it
[ns] Res: LossMoniitor: npkts
Hi Mrs. Franco, look into ns manual for trace file format. each field into file represents an information about the traffic. an other source is file ns simulator for beginners, which i am sending attach. A other doubt about this matter, ask us again. regards Breno Caetano da Silva Bacharel em Ciências da Computação - UFPI Mestrando em Engenharia Elétrica Escola de Engenharia de São Carlos - EESC Universidade de São Paulo Email: [EMAIL PROTECTED] [EMAIL PROTECTED] Fone: (+5516) 81449079 (+5516) 33738149 - Mensagem original De: Pasquale Franco [EMAIL PROTECTED] Para: ns-users@ISI.EDU Enviadas: Sexta-feira, 3 de Outubro de 2008 7:04:09 Assunto: [ns] LossMoniitor: npkts Hi, I use the command: set RCVD [$sink set npkts_] to know how many packets have been received by ALL node.

Re: [ns] TCP ACKs - change route
Hi Tatiana, I am also looking for the answer to the same question. In my simulation I need to send TCP ACKs on a different route as compared to the TCP data packets. Since I am using wireless MAC the concept of link does not apply there. Hence, the routing related command does not apply to my scenario. Which means I will have to hack in the code to force the ACK packets to take a specific path. As of now I am not sure how to do that. However, I read in the manual that all the route specific commands use link concept. The link concept is applicable to wired scenarios. I believe if you are using wired links then it should be possible to use rtproto manual or rtproto static or something similar to achieve the forced routing of the ACKs. I hope this helps.

I'm trying to send the ACKs for the TCP packets using specific routes. In the tcp-sink.cc module there is a function ack() which sends ACK packets using send(P, 0) method. Does anybody know where the function is defined and there the destination for the packed is specified? Please, help.
[ns] how to find where a variable is initialized
Hi, everyone, How to find where a variable is initialized ? I add a new mac same as mac-802_11, but it puts warning MAC_RMAC: accessing MAC cache_ array out of range (src 0, dst 1, size 0)! I found out that it is due to cache_node_count_ = 0. It must be set somewhere in MAC/802_11, but I do not know where to find it. I think it might be in a .tcl file. Any help is appreciated!

No, it is Zone Routing Protocol. this problem is fixed. but there is core dumped. How can i solve this segmentation fault.

[ns] segmentation fault (core dumped) using ZRP in ns-2.27
Dear ns-users,
I installed Zone Routing Protocol (ZRP) on ns-2.27. However, when i use ZRP
to run below example, I got the segmentation fault (Core Dumped).
I don't know why this kind of error is occured. if anyone knows, please help
me.
thank you very much in advance

[ns] prob with NAM
Hi, When i try to run any existing tcl file esp for wireless 802.11 simulations - the NAM is not working fine with ns-2.31 aand ns 2.33 . The error is *node 0 not found.. node 1 not found.. etc..* These errors , as i understand, come when the nodes are not in the range of NAM.. (??) Ialso came across the 'playing backwards' technique- But it worked only to an extent and it doesnt make any sense. why doesnt even the example codes for wireless work on NAM ? Could anybody help me.. Thank you Sivasankari
