I want to integrate 6LoWPAN with PMIPv6 in ns2 to compare my proposed protocol with other mobility management protocols in LoW Power Wireless Networks.

Can any one help in this regard?

»» ns 2.35 will this work on it «« :

ns-2.35 has a very different setup of the MAC code : ns-2.35/mac/**.

.... So usually it's not possible.

As far as I remember nobody have used 6LowPan with ns-2.35 .

And there isn't any known examples of nistmob + PMIPv6 with ns-2.35 .

»» I have ns 2.35 will this work on it «« :

You can have as many ns-allinone-2.xx as you want, installed at the same time

Not quite clear what you are doing.

Please specify your OS. Name, version, architecture please.

Like this : Ubuntu 10.04 - i386 .... Ubuntu 12.04 - amd64 .... etc. etc.

..... And please tell how you got a command "ns" which might run the simulation.

Note : "ns-new-name" is preferred when it's a new changed / patched ns2.

https://drive.google.com/file/d/1FCjn-9fkR7tKeqClUpHsleaEdnoKRZzq/view?usp=sharing

You are not supposed to run 'ns' from ns-2.29/pmip6/ ... and no default `pmip.tcl´ in ns-2.29/pmip6/.

Example :

nist-pmip6-6lowpan-ns_2.29-ubuntu12_i386.deb provides /usr/local/bin/ns229-pmip6-nist-6LoWPAN-el6

.... So the simulation command is , example :

$ cd ex-nist-2018/ ## the examples can have any location in /home/**

$ ns229-pmip6-nist-6LoWPAN-el6 pmip.tcl

Ref. nist-mob_examples-01.18.tar.gz
https://drive.google.com/file/d/1EpQ7ccUMCsZPd_woXjkJbr4jwx9yuI9o/view?usp=sharing

Your error »»invalid command name "Agent/PMIPv6"«« :

You are using a copy of the executable 'ns' with no PMIPv6.

Also important : Your simulation command is missing. Please show.

Ubuntu : Please specify version and architecture.

Like Ubuntu 12.04 - amd64.

If it's an Ubuntu version later than version 11.04, the ns2 app nist-pmip6-6lowpan-ns_2.29-ubuntu12_i386.deb ( 2.8MB ) is required for test. Provides /usr/local/bin/ns229-pmip6-nist-6LoWPAN-el6 .

Which means the "ns command" is $ ns229-pmip6-nist-6LoWPAN-el6

Download .... and install :

$ sudo gdebi Downloads/nist-pmip6-6lowpan-ns_2.29-ubuntu12_i386.deb

If the OS is 64bit, some 32bit dependencies will be installed too.

I install, nist-pmip6-6lowpan-ns_2.29-ubuntu12_i386.deb. And use "ns command" is $ ns229-pmip6-nist-6LoWPAN-el6 for simulating pmip.tcl file.

Simulation runs successfully nam and tr files are also created.but when analyze by awk code it shows packet sends 1000

Received 0

Dropped 1000

»» when analyze by awk code it shows packet sends 1000 «« :

Depends which script you are using. Please specify / upload / attach.

None of the many awk scripts I tested earlier today worked OK with the `trace.out´, so please do not expect it to be easy.

There isn't any "general" about creating an ns2 awk script. The script must be a match for the trace file !

I found one "usable" in my storage : packets.awk ... from Awk+Perl_ns2-scripts-0520.tar.gz .

$ awk -f packets.awk trace.out
GeneratedPackets = 8870
ReceivedPackets = 11472
Packet Delivery Ratio = 129.335
Total Dropped Packets = 7589
Average End-to-End Delay = 5001.53 ms

---------------------

My trace.out has 237,029 lines, is 15.8 MB. How is yours ?

All 240 scripts, Awk+Perl_ns2-scripts-0520.tar.gz

https://drive.google.com/file/d/1DoZDQ7gJzKTIdlxLXjiVO28VpK1pJjq-/view?usp=sharing

P.S.: I have all major Ubuntu versions 8.04 ... 20.04 installed, to test ns2 simulations.

So I can also do a test with your version, when you specify the version.

... Which means received (r) = 11701 packets ( 225105 - 213404 ).

@khanlo... , Hi.

Later Ubuntu Xgraph packages : No `xgraph´ package in the new Ubuntu versions.

Ubuntu 17.10 : I'd suggest the older package that we are using in 18* ... 20.04 → →

xgraph_12.1-17_amd64.deb ( It's the Ubuntu 16.04 version, I think )
