Hi,
have followed your installations procedure on a fairly new ubuntu 7.10
When starting my terminal I get following warning:
“bash: LIB:/usr/local/lib: No such file or directory”
Do you have an idea what the reason for this is?
thx

Assalamualaikum Mr. Udin,
Nice website. Thanks for the knowledge shared in this site. .
me and a few of my friends are also working on NS2 simulations for Wireless sensor network and wired network . Me my self interested in simulation and network simulators. However due to workload and other constraints the progress are very slow. This kind of website help me a lot. Thank U.
Semoga cita2 saudara tercapai.

under section 8, the command “configure” does not work. It gives the error “bash: configure: command not found” . I tried running “sudo apt-get install build-essential” as well. But still does not work. Any help appreciated.
Thanks…
Udin Harun Said :
It should be work.
Read this document carefully – http://docs.tinyos.net/index.php/Getting_Started_with_TinyOS
I think you need to move to ‘tinyos-2.x/tools/tinyos’ directory, after that do ‘configure’ command.
If still not success, try several times 🙂
I try several times untill success 🙂
Good Luck
hello there. i have problems on using imote2. was wondering if you could help me? i don’t know of any application that is able to show temperature readings. many thanks.
Dear Brother, Assalamu alaikum wa rahmatullah. I was googling for some info on WSN and came to your site. I have an important presentation tomorrow, but am just moving around in your site!! Believe me, I think you are a good person and is gifted with good sense of Islam. I am just more than happy to see a young researcher with true love of Allah. May Allah help you to finish your PhD with some good publications and in shortest possible time. May Almighty give your family the right kind of sabr in your absense. From the core of my heart, I pray to Allah for your success.

i am very impressed by ur islamic style and appreciate the way u r looking at ISLAM.I am a masters student currently in my final sem and have 2 options to do my major project
1.computer networks
2.wireless communication
plz let me know which is best suitable for me as i am a communictaion student and also suggest me a title .
SHUKRAN JAZAKALLAH
Udin Harun Reply :
Waalaikumsalam brother Aziz.
Thank you for visiting my web blog 🙂
I am also still learning about Islam.
About your final project, in my opinion, if you are a communication student, I think wireless communication topic is more suitable for you. But, I am afraid I cannot suggest you a title. I think you can search papers/journals (such as IEEE, ACM) related to communication to get suitable topic based on your background for your final project. You can get more idea after read several papers/journals.
Jazakallah Khoiron.
thank you very much brother for your precious advice.

If you take the code from book site or rewrite it, it should be no problem.
I have experienced similar problem before.
If you use microsoft visual C++ or other tools, you need to make sure that you are building a Windows GUI application, and not console application in the first step you build project.

I am a newer about NS2. my interesting is to implement the P2P and star topology withe the MAC&& PHY 802.15.4 in non beacon enabled mode, I beginer for the tcl script wpan_demo2 for star and i change the $ns_ at 0.0″$node_(0) sscs startCTPANCoord 0 O O
$ns_ at 1.5″$node_(1) sscs startCTDevice 0 1 0 ” ;#;# startDevice is it true?
to study the metrique performance for the energy, pakets delivery ratio traffic load(wat means?) and delay+troughput but I found some difficulties for the comprehenssion for the tcl script for exemple:
1)Mac/802_15_4 wpanNam PlaybackRate 3ms
2)puts [format “Acknowledgement for data : %s” [Mac/802_15_4 wpanCmd ack4data]]
3)$ns_ at $appTime1 “Mac/802_15_4 wpanNam PlaybackRate 0.50ms”
4)$ns_ at [expr $appTime1 + 0.5] “Mac/802_15_4 wpanNam PlaybackRate 1.5ms”
$val(traffic)traffic 1 0 0.2 $appTime1
$val(traffic)traffic 2 0 0.2 $appTime2
$val(traffic)traffic 3 0 0.1 $appTime3
can you sir explain me, to help me to send me the tclscript for nonbeacon star or p2p and AWK.
Thank you sir

Udin Harun Reply :
Waalaikumsalam wr.wb.
I do not have TCL script for non-beacon. I research on Cluster-tree with beacon.
However, the tutorial said you can change the value of SO and BO equal to 15 for non-beacon mode.
1)Mac/802_15_4 wpanNam PlaybackRate 3ms
It is just for NAM simulation rate. you can change ‘3ms’ to modify the speed of NAM simulation.
2). puts [format “Acknowledgement for data : %s” [Mac/802_15_4 wpanCmd ack4data]]
I think it is used for ‘your simulation use ACK or not’
3). $ns_ at $appTime1 “Mac/802_15_4 wpanNam PlaybackRate 0.50ms”
Like number 1). at time1, the speed of NAM is 0.5ms
4). $ns_ at [expr $appTime1 + 0.5] “Mac/802_15_4 wpanNam PlaybackRate 1.5ms”
$val(traffic)traffic 1 0 0.2 $appTime1
$val(traffic)traffic 2 0 0.2 $appTime2
$val(traffic)traffic 3 0 0.1 $appTime3
$val(traffic)traffic 1 0 0.2 $appTime1 ==> ‘1’ is the source node, ‘0’ is the destination node, ‘0.2’ is interarrival time (packet will be generated every 0.2 second). For detail, you can read NS2 manual.
For example of AWK and metric performance, you can study first from here : http://www.ifn.et.tu-dresden.de/~marandin/ZigBee/scripts.html
Thanks,

maaf andai saya mengganggu..
saya menghadapi sedikit masalah mengenai tcl code untuk disimulasi menggunakan ns2.
saya sedang membuat kajian mengenai meningkat performance untuk mobile sensor network bagi ieee 802.15.4. masalah yang saya hadapi, apabila saya run contoh code yang terdapat dari http://www.isi.edu. banyak file yg tidak dapat dibuka.saya harap tuan dapat membantu sy..terima kasih.
Udin Harun :
Waalaikumsalam wr.wb.
untuk tcl code IEEE 802.15.4, sister Farah bisa belajar source code ns2 dari sini :

dan
http://www.ee.washington.edu/research/funlab/802_15_4/
assalamualaikum
Maaf sekiranya saya mengganggu. Saya sedang membuat kajian berkenaan IEEE 802.15.4 WPAN, iaitu performance on energy consumption dan delay apabila vary SO and BO.Saya sudah dapat reference code utk vary tersebut tapi mengalami masalah untuk execute graf drpdnya.Saya sudah cuba byk kali tapi tak boleh juga.
terima kasih
Udin Harun :
Waalaikumsalam wr.wb.
untuk mendapatkan energy consumption dan delay, brother syuhada bisa menghitungnya dari output trace file (file.tr) menggunakan file AWK. Silahkan dipelajari file awk dari link dibawah ini, selanjutnya bisa dimodifikasi sesuai dengan kebutuhan risetnya 🙂
http://www.ifn.et.tu-dresden.de/~marandin/ZigBee/scripts.html
http://www.ifn.et.tu-dresden.de/~marandin/ZigBee/avg_throughput.awk
salam,
En. Izzul graf tu mmg hanya boleh execute dari fail AWK itu sahaja ke?sebab dari contoh 802.11 yang ada bahagian execute graf, ia boleh execute dari modified tcl code aja. Saya udah try combine wpan_demo2.tcl(802.15.4) bersama certain code xgraph dari(802.11). Saya mau tau adakah boleh caranya begitu kerana saya tidak dapat juga execute graf dan vary SO BO tersebut.Terima kasih.
udin harun reply :
Saya juga pernah mencoba memakai Xgraph, tetapi tidak jadi saya gunakan karena hasilnya tidak sesuai dengan paramater yang saya inginkan. Saya lebih suka menggunakan file AWK untuk menganalisa output trace file (file.tr). Setahu saya, modifikasi file tcl dan me-running file tsb akan menghasilkan output trace file (file.tr). Dari trace file tsb kita bisa menganalisa energy dan delay.
Jika brother syuhada menggunakan Xgraph 802.11 untuk file tcl 802.15.4, saya pikir itu tidak tepat, karena format trace file 802.15.4 berbeda dengan format trace file 802.11.
assalamualaikum,
Saya ingin bertanya lagi apakah maksud bagi
1) “$node_(0) NodeLabelPan Coor”
2) “$node_(0) sscs startPANCoord 1”
3) “$node_(1) sscs startPANCoord 1 0”
4) “$node_(2) sscs startPANCoord 1 3 3”
5) “$node_(3) sscs startPANCoord 1 6 6”
Terima kasih.
Waalaikumsalam wr.wb.
SSCS interface :
$node sscs startPANCoord
This command can be used to start a new PAN, and the
corresponding node will serve as the PAN coordinator.
– If some parameters are omitted, the default values shown above
will be assumed.
Contoh :
“$node_(2) sscs startPANCoord 1 3 3″
maksudnya node_(2) berfungsi sebagai PAN Coordinator, 1 artinya PAN coordinator mengirim beacon, nilai BO = 3, nilai SO = 3.
Salam,
Saya tidak faham sangat pki AWK itu.Untuk pengetahuan En. udin saya install ns2 pki ubuntu 9.10 kt pc saya mengikut dlm blog En udin tsb tapi saya mengalami mslh run project yg mmgunakan c++ command(NS2 Simulator for IEEE 802.15.4 by Jianliang Zheng,SAIT-CUNY Joint Lab).Mula2 ia dispaly “g++ nt found pastu saya cuba wat sudo clean,sudo update dan sudo apt-get install build-essential(manual dlm internet)tapi apabila saya cuba run ia display “no such file into directory,no input file”.Saya save programnya dlm filename.cpp. Betul ke caranya itu?
Assalamualaikum,
Terlebih dahulu saya ingin berterima kasih pada En.Izzul dan En. Udin Harun kerana sudi menjawb pertanyaan2 saya.Sekarang saya udah semakin faham berkenaan command AWK tsb after refer website ni “http://www.ifn.et.tu-dresden.de/~marandin/ZigBee/scripts.html” tapi saya ada sedikit masalah didalam step analyze the program.Bolehkah terangkan bagaimana saya boleh execute macam yg diajar dalam website di atas.Terima kasih.

assmlkm pak udin harun….saya mau bertanya,, apa maksud sink pada WSN, apakah sink merupakan sebuah PAN coordinator?
Udin Harun:
waalaikumsalam.
sink itu destination node. Node akhir yang menerima paket. tidak mesti harus PAN coordinator. Tetapi secara umum PAN coordinator disetting menjadi sink node.
salam pak udin harun,
saya sedang membuat penelitian tentang multi sink tree untuk zigbee, beberapa pertanyaan dari saya,
– apa saja tugas sink?
– bagaimana mengeset node di ns untuk menjadi sink tanpa harus menjadi PAN coordinator?
terimakasih
udin harun reply::
– sink itu istilah node tujuan paket yang dikirim. biasanya disebut destination node atau sink node.
– sink node tidak mesti harus menjadi coordinator. setting device node juga bisa jadi sink.
tinggal setting disininya saja : $val(traffic)traffic 4 2 1 $appTime1. misalkan paket dikriim dari device node-4 ke device sink node-2 dengan interarrival time 1.

Mestinya hal itu bisa dilakukan di NS2 asalkan mau menguprek script NS2 🙂 .
Beberapa riset paper membahas coexistent antara 802.11 dan 802.15.4.
Tetapi saya tidak tahu apakah mereka menggunakan NS2 untuk simulasi atau menggunakan jenis simulator yg lain.
Brother Udin Assalammu alaykum
I beleive you have done work using NS2. I am a beginner I am trying to plot throughput agains time for a wireless network using cbr traffic. Could you please tell me how to extract the throughput and time using awk file from .tr file. Jazaka allahu khair. By the way I am from Falastine (Palestine). Do you use skype? if so could you email me your skype name.
Many thanks brother

Waalaikumsalam brother Hussain. I plot throughput vs. traffic load using poisson traffic. I analyze them using awk from .tr file. You can study how to extract the throughput from this link http://www.ifn.et.tu-dresden.de/~marandin/ZigBee/scripts.html, they provide the example of awk file for throughput, then you can modify it according your requirements.
Ok, I will sent my email and skype to your email.

assmlkm pak udin harun,
melakukan simulasi zigbee 802.15.4, star topologi saya mau bertanya kenapa jika kita melakukan vary bo so
mengapa saat bo=s0 yang bernilai tidak nol pada saat kanal bo=so= 1 hingga 9 ,, sedang bo=so=10 hingga 14 bernilai nol,,saya menggunakan trafik cbr
sebenarnya apa yang telah terjadi didalamnya..
terima kasih pak udin…wassalam
Waalaikumsalam.
Saya biasanya memakai traffic poisson.
Saya tidak tahu pasti ada apa, Coba dicek simulation time-nya, mungkin perlu ditambah lagi waktu simulasinya untuk so=bo yg besar.
Karena semakin besar nilai BO, jarak waktu pengiriman paket beacon lebih lama, waktu yg dibutuhkan untuk semua device node semakin lama untuk sinkronisasi dengan coordinator node.
selain itu dicek apakah device node sudah sinkronisasi dg coordinator atau belum.
hello
I’m student . I’m wondering how can I get the same results of code for “A comprehensive performance study of IEEE 802.15.4” paper. because I have that code for all scenarios which mentioned in this paper I have tried to get it. but I have failed. so, if you have the Excel file of results please send it to me.
regards
I am sorry. I don’t have excel file results of that paper.
maaf kurang lengkap pak udin harun.maksud saya adalah nilai througput

I’m a newer about NS2. I couldn’t understand the parameters that I got from trace file. wish are:
s 30.154977941 _59_ MAC — 98 exp 97 [0 1f 3b 800] ——- [71:0 74:0 29 31]
please explain to me every parameter what is meaning?
Regards
waalaikumsalam wr.wb.
s = packet send
30.154977941 = time for send packet
_59_ = node which send packet
MAC = network trace level at MAC layer
98 = ID or Event Identifier
exp = packet type
97 = Packet Size
0 = Destination node, hexadecimal.
3b = Source node, hexadecimal
You could study from here http://nsnam.isi.edu/nsnam/index.php/NS-2_Trace_Formats#Old_Wireless_Trace_Formats
السلام عليكم
thank you for reply. I’m not good about the programming. I need to calculate the packet delivery ratio VS traffic load (pkt/s)and also Delay VS traffic load.
BEGIN {
count = 0;
}
{
action = $1;
time = $2;
node_id = $3;
layer = $4;
flags = $5;
seqno = $6;
type = $7;
size = $8;
a = $9;
b = $10;
c = $11;
d = $12;
energy = $14;
for(seqno = 0; seqno < 1; seqno++) {
if((node_id = "_0_" && action == "s")) {
count++;
}
}
}
END {
printf("%d\n",count);
}
this code for AWK .I have attempted to modify this code but I have just failed. can you help me how can I modify it?.
and the following is part of the parameters from trace file:
v 20.5 eval {set sim_annotation {(at 20.5) cbr traffic from node 67 to node 45}}

Assalamu alaikum wa rahmatullah Brother in Love of Allah, . I was googling for some info on ZigBee and came to your site. It is a nice muslim website such this website and it is gifted with good sense of Islam. I’m sure you are a good muslim person . I am personally admire you and happy to see a muslim researcher whose truly works hard and just do it for love of Allah. May Allah help you to give you and your family his mercy and success in your life.

assalamualaikum bapak,, saya sangat tertari akan wilayah sensor ini..saya ingin bertanya… apakah pengaruh beacon order dan superframe order pada jaringan 802.15.4 untuk topologi cluster tree
apakah untuk cluster tree berbeda dengan single hop star,, dan dimana letak perbedaannya..?
wassalam
Udin Harun reply :
Waalaikumsalam wr.wb.
Beacon Order (BO) digunakan untuk menentukan Beacon Interval (BI) dan Superframe Order (SO) digunakan untuk menentukan ‘Active Period’ atau Contention Access Period (CAP) pada suatu superframe. perubahan nilai BO dan SO bisa berpengaruh pada hasil throughput, latency/delay time, energy efficiency dan jumlah paket yg dapat ditransmit oleh device node.
BO dan SO berpengaruh sama baik di cluster tree dan single hop star. PAN coordinator mengirim beacon ke Coordinator node, Coordinator node mengirim beacon ke device node.
asalamualaikum…
pa saya sedang mgerjakan tugas akhir..dengan judul “analisis penggunaan protokol routing AODV pada WSN”
saya baca dari literatur tentang Zigbee untuk routing zigbee ada 2 yautu HTR dan AODV…nah saya gunakan AODV..tapi masalahnya :
1.saya harus buat topologi mesh nya untuk node – node yang berfungsi jadi router…gmana caranya agar suatu node dapat memforward paket yang datang, k node tujuan.misal node 1 kirim ke 2 tapi jangkauan 1 tidak bisa ke dua jd harus multihop.
2.bagaimana membuat aliran data jadi multihop??
3.tolong beri referensi..kira2 saya bisa dpet tcl script untuk contoh mesh topologi wireless
teima kasih pak..mhon bantuannya
Udin Harun reply :
Mohon maaf. Riset saya saat ini lebih banyak fokus belajar di area MAC layer. Saya belum mendalami tentang routing di bagian network layer. Jadi maaf tidak bisa membantu solusi teknis tentang AODV.
Assalamu’alaikum wr.wb.
Pak, saya sedang melakukan penelitian mengenai Manet heterogen.
Bagaimana cara menset pada NS2, agar setiap node memiliki transmission range yang berbeda? misal jumlah node = 10 node; 4 node memiliki jangkauan transmisi 100m, 3 node 150m dan 3 node 200m. Mohon bantuannya.
Terima kasih.

sir,
May i know how to create a cluster in ns2.34 for WSN
as i m new to this area..
kindly mail me

hi sir,
My area is wireless sensor networks in home automation.im trying to implement a greedy algorithm heuristic routing protocol (GAHR) and i have to compare it with aodv.There is hardly any material i can find…kindy help…should i do it in ns2 or matlab ? Is there any code available ?
Please mail me..

what does mean beaconing coordinator ?
regards
Waalaikumsalam.
beaconing coordinator: beacon packet from coordinator. Coordinator will sent beacon to its children nodes regularly.
السلام عليكم ورحمة الله
I neend to change the percentage of coordinators beaconing in my simulation how can I do it as (0%, 25%,50%,75%,100%).

Waalaikumsalam.
There 2 kinds of CSMA/CA: beacon or beaconless.
Beacon transmission depend of the value of BO.
can I do that from this command:
$ns_ at 0.0 “$node_(0) sscs startCTPANCoord 0” ;# startCTPANCoord
Regards
السلام عليكم ورحمة الله
how can change BO ? Is there any related between BO and So?
Regards
Waalaikumsalam.
What’s kind simulator do you use ? You can change the value of BO and SO in the source code. the value of SO <= BO. You could read standard IEEE 802.15.4 first for clearly.
السلام عليكم
I have simulated multi-hope scenario to study association efficiency Vs beaconing coordinators ratio.
Regards
السلام عليكم ورحمة الله وبركاتة
I need to ask you equation about the number that located after this command :
$node_(0) sscs startCTPANCoord
$node_(0) sscs startCTPANCoord 0
$node_(0) sscs startCTPANCoord 1
$node_(0) sscs startCTPANCoord 1 2 2
pleas explain it to me
Regards
السلام عليكم
I need to create AWK file to calculate attempts per successful association vs Beacon Order. but I have confused with condition can help me please
