sumu on ns2

[Academic Group of NS2]

when i run the command "python /usr/local/src/sumo-src-0.32.0/sumo-0.32.0/tools/randomTrips.py -n map.net.xml -r map.rou.xml -e 50 -l" i face the error called

python: can't open file '/usr/local/src/sumo-src-0.32.0/sumo-0.32.0/tools/randomTrips.py': [Errno 2] No such file or directory. how can fix it please help me.

$ locate randomTrips.py

/usr/local/share/sumo/tools/randomTrips.py

.... Usually  /usr/local/src  is not used for anything !  !

Use another "Delay script" ....  An awk or perl script must be a match for the trace file to analyze.

And :  Be aware that  $ns use-newtrace enables the new trace format used by most scripts.

No  line with  $ns use-newtrace  in your simulation.tcl will write an "out.tr" in  `old trace format´.

hi sir based on your recommendation i tried to find the network performance like that of throughput, packet delivery ratio, delay and routing overhead for ns2 .tcl files but when i troed to find the delay and network over head on terminals using the command awk -f filename.awk filename.tr, it says that 

awk: delay.awk:82: (FILENAME=vanet.tr FNR=1473998) fatal: division by zero attempted, there fore how can fix this error? thankew very match.

Hi.

»» awk: delay.awk «« :                   Missing information →

Plenty of files with the name  delay.awk :  Please attach the file, delay.awk

** You forgot to confirm that you tried out all 25 possible files.awk, files.pl .

And that you also tried using a version of vanet.tcl with a line   $ns use-newtrace

Please attach vanet.tcl and the connected traffic / movement files.

....... Unless it's about one of my examples in Vanet-examples-10.19.tar.xz

https://drive.google.com/file/d/1FgTtKMYBmTa56I0LkDvcb7yN9f5GNxCd/view?usp=sharing

... with no modifications. Then please specify.

[lework dagne]

hello sir please donot take your help from me? and thanks for your valuable help? when i run this as you tell me..there iis a trace file but there is no any packet sent and received in olsr...at time 0 always what the problem?

end to end delay.awk also canot find the e2e delay ..because it say division by 0

$ ns235-olsr-64 4-olsr-wca.tcl 50

.......  The files oWCA.nam 208.9kb,  oWCA.tr 528.4kB are created.

$ grep "s " oWCA.tr | wc -l
384
$ grep "r " oWCA.tr | wc -l
384

...... so 384 packets are sent, and 384 packets are received, according to a simple count.

AWK example :

$ awk -f qos.awk oWCA.tr
       startTime:  0
        stopTime:  2
    receivedPkts:  1256
   avgTput[kbps]:  151.286

Do not rely on one test file = your unknown `delay.awk´.

• All possible choices of analyzing scripts must be run.
• You have ~20 scripts to run :
  

all-2.awk
Avg_Del.awk
Avg_Del_Flow.awk
Instnt_Del.awk
Instnt_Del_Flow.awk

delay_alterado_einar.awk
delay.awk
delay-e2e.awk
delay-link.awk
delay_original.awk
del-ratio.awk
insdelay_tcp-cbr-vbr.awk
measure-delay.awk
thr_drop_delay.awk

for what reason makes you to run by starting/typing ns235-olsr-64 ????rather than ns?and can i use bandwidth,mobility/jitter from hello messages and delay instead of distance,mobility and power?

[lework dagne]

what is the difference between End-to-End-Delay##.pl
Endtoenddelay-Xgr.awk ,..those two files?how we use to run owca.tr and what we got.?excuse me i didnot have knowledge about these area..i face many problems and makes you busy,,.because i am stressed. 

[knudfl]

»» for what reason makes you to run by starting/typing ns235-olsr-64 «« :

Imagine you have several ns2 installs. 32 and 64bits executable.

They cannot all have an "ns command".

..... I have ~300 different patched ns2. All the executable ns-name are in /usr/local/bin/.

See attachments, usr.local.bin-29Sep19.txt, ns2-INFO.txt

»»can i use bandwidth,mobility/jitter from hello messages and delay instead of distance,mobility and power«« :  Where and why ? Please make your own investigations, Google is your friend.

ns2 doc https://www.isi.edu/nsnam/ns/doc/index.html

... And please be aware that official ns2 support ended many years ago.

The ns2 developers are all busy with ns3, and will answer ns3 questions only.

And I only have a limited knowledge of ns2.
