[ns] Problem with "regagent_"

a problem while I run a wireless simulation.first is the tcl

[ns] How to get an agent's trace file?
Hi everyone,I want to know how to obtain the trace file of a specific agent in ns2. I want to know what the specific agent did, but I do not know how to trace the agent. Any suggestions will be appreciated.Thanks in advance. Yutao Wei,CCMIP, Shandong University, P.R.

[ns] Distance function in mobilenode.cc
Hi all, I modify the AODV protocol, in aodv.cc I want to calculate the distance between a node and its neighbors with using the distance function in common/mobilenode.cc having as parameter "MobileNode" type how can i proceed. (In aodv index is a nsaddr_t type) thank you for your Help - Ne gardez plus qu'une seule adresse mail ! Copiez vos mails vers Yahoo! Mail
Re: [ns] urgent help with trace graphs
Hello, I am having the same issue. Did you managed to interpreter this trace file and i so, what command did you use? bageira wrote: > > hi...i'm in urgent need of help with creating a trace graph from a trace > file.i'm using ns-2 and my code is for a wimax module. i have a trace > file of this kind: > > s 0.000100840 _0_ MAC --- 0 DLMAP 24 [0 0 0] --- [0:0 0:0 0 > 0] > s 0.000100840 _0_ MAC --- 0 ULMAP 28 [0 0 0] --- [0:0 0:0 0 > 0] > s 0.000100840 _0_ MAC --- 0 DCD 116 [0 0 0] --- [0:0 0:0 0 > 0] > s 0.000100840 _0_ MAC --- 0 UCD 180 [0 0 0] --- [0:0 0:0 0 > 0] > r 0.000101598 _5_ MAC --- 0 DLMAP 24 [0 0 0] --- [0:0 0:0 0 > 0] > r 0.000101598 _5_ MAC --- 0 ULMAP 28 [0 0 0] --- [0:0 0:0 0 > 0] > r 0.000101598 _5_ MAC --- 0 DCD 116 [0 0 0] --- [0:0 0:0 0 > 0] > r 0.000101598 _5_ MAC --- 0 UCD 180 [0 0 0] --- [0:0 0:0 0 > 0] > r 0.000101638 _1_ MAC --- 0 DLMAP 24 [0 0 0] --- [0:0 0:0 0 > 0] > > but i dont know what command to type in the console to have it plotted on > a trace graph so i can analyse it. could someone pliz help me??? > thanks alot > -- View this message in context: http://www.nabble.com/urgent-help-with-trace-graphs-tf3877163.html#a11274838 Sent from the ns-users mailing list archive at Nabble.com.
[ns] how does monitor-queue works?
Dear NS users I simulated a simple network consisting of 2 sources and 3 links, using ns2.29. In this simulation I want to monitor the queue between nodes n3 and n4. I used the following command to do this: set qmon [$ns monitor-queue $n3 $n4 [open qm.out w] 0.1]; [$ns link $n3 $n4] queue-sample-timeout; At the end of simulation "qm.out" is created. The 4'Th column must be the queue size in bytes and the 5'Th column must be queue size in packets. These variables must be integer variable, whereas related columns in "qm.out" are real value numbers. I want to know is this normal or it is a bug. How can I collect the queue size correctly, if it is a bug? Or how can one interpret this (expected integer value data (queue_size) are real value data in practice). Some lines of "qm.out" are presented here. 0 3 4 0 0 0 0 0 0 0 0 0.10001 3 4 0.0 0.0 0 0 0 0 0 0 0.20001 3 4 0.0 0.0 0 0 0 0 0 0 0.30004 3 4 0.0 0.0 0 0 0 0 0 0 0.40002 3 4 0.0 0.0 0 0 0 0 0 0 0.5 3 4 0.0 0.0 0 0 0 0 0 0 0.59998 3 4 0.0319987601 0.000799969006 3 3 0 1120 1120 0 0.69996 3 4 151.42379 0.145599798 8 8 0 6320 5200 0 0.79993 3 4 650.623263 0.625599294 18 17 0 16720 9360 0 0.89991 3 4 1890.303999819 1.8175983 30 27 0 29200 10400 0 0.99989 3 4 4367.99627 4.1647 42 36 0 41680 9360 0 1.0999 3 4 6880.639998775 6.61598833 54 46 0 54160 10400 0 1.2 3 4 9383.295997056 9.02237151 66 55 0 66640 9360 0 1.3 3 4 11870.97599499 11.4143519 78 65 0 79120 10400 0 1.4001 3 4 14386.9439931 13.8335334 90 75 0 91600 10400 0
