How are you Friends? My simulation software is NS2, and i am a novice in using it and i feel that it is like a big sea, i do not know its bounderies. So please help me if you can. In my simulation, when generating a new node in the simulation it should has unique IP address (that consists of 16 bits) that i could use again in the remaining simulation. Plaese, is there any one that can guides my to do this? I will be so grateful. Many thanks, M.F.

hi all in general how to capture return value of c++ function in tcl? -- Amin Irandoost
[ns] please help out
hi all I have a very urgent and desperate call for help. I am using NS2-31 and EDCA patch of TU Berlin, for 802.11e. Please guide me how to: 1. get the MAC level throughput trace file (the TCL code etc.) 2. how I can evaluate the behaviour of H.264 over NS2 for some video frames. Probably I am looking for a trace file containing the type of frames (I,P,B), thier time stamps and sizes? Any tool to do it? Thank you very much. very kind regards B
[ns] please help out
I am working on 802.11e as well. 1. For me the easiest answer was to not worry about the ns trace file, and create my own. I count throughput at the MAC level by printing bytes sent during the simulation, and use a perl script to get the statistics afterward. 2. There are some tools to help you do this. http://www.tkn.tu-berlin.de/research/evalvid/EvalVid/docevalvid.html I am using an H.264 profile, but accuracy isn't important so I just used a mostly equivalent pareto VBR source. I hope this helps! Will Spearman Clemson University > hi all > > I have a very urgent and desperate call for help. I am using NS2-31 and EDCA > patch of TU Berlin, for 802.11e.

[ns] Please help me
Dear All, I am using ns-2.34 and have written some c++ codes and added them under the ns-2.34 sub-directory. I did "make clear", but when I did "make" to re-compile, the following error (see below) occur. Can anyone help me. Thanks alot. M.A. ./common/ptypes2tcl > gen/ptypes.cc /bin/sh cannot create gen/ptypes.cc permission denied make: *** [gen/ptypes.cc] Error 2
[ns] please help in ODMRP
hi, I m working on ODMRP of ns-2.1b8. The simulation is working properly but when i m running mcast_total.pl script to get the packet information the error is like CBR Logging error. I think the problem is because of the change in the trace format ns-2.1b8and ns-2.28. But actually i m not understanding the trace format. the trace file looks like: r 18.873611979 _0_ ODM --- 12 cbr 64 [0 4 800] --- [10:32770 32770:32770 254 0] [6] 2 0 M 18.99344 45 (907.63, 361.14, 0.00), (93.13, 144.01), 1.15 s 19.152399956 _10_ AGT --- 13 cbr 64 [0 0 0 0] --- [-1:-1 32770:32770 32 0] [7] 0 0 r 19.152399956 _10_ ODM --- 13 cbr 64 [0 0 0 0] --- [-1:-1 32770:32770 32 0] [7] 0 0 s 19.155637540 _10_ ODM --- 13 cbr 64 [0 0 0 0] --- [10:32770 32770:32770 255 0] [7] 0 0 r 19.156825588 _12_ ODM --- 13 cbr 64 [0 a 800] --- [10:32770 32770:32770 255 0] [7] 1 0 r 19.156825588 _12_ AGT --- 13 cbr 44 [0 a 800] --- [10:32770 32770:32770 254 0] [7] 0 1 f 20.454737907 _12_ ODM --- 19 ODMRP 36 [0 a 800] --- [10:255 32770:255 254 0] -32770- 12 [1 1 1 0] [0 0 0 0] (0, 0) f 20.454898315 _7_ ODM --- 19 ODMRP 36 [0 a 800] --- [10:255 32770:255 254 0] -32770- 7 [1 1 1 0] [0 0 0 0] (0, 0) r 20.455961929 _10_ ODM --- 19 ODMRP 36 [0 c 800] --- [10:255 32770:255 254 0] -32770- 12 [1 1 1 0] [0 0 0 0] (0, 0) please help me if sombody knows the solution.

Re: [ns] Please help me
Normally you want to do the opposite: cal otcl in c++ and get the returned
string.
For that you should use the macros in my file ns_utils.cc
http://tagus.inesc-id.pt/~pestrela/ns2/contributed_code.html#_Toc147652229
eg:
TCL_EVALF("%s some_instproc %d", name(), MH_iaddr);
assert( *TCL_RESULT );
etimip_RO_id = atoi(TCL_RESULT);
--
for your particular problem, you should use the Command() interface that all
c++ objects have

Re: [ns] please help in ODMRP
Hi Pooja,
This is because mcast_totals... script try to parse trace outputs differently,
Change the parse format from
if($LINE =~ / --- \[(\W*)(\d*):(\W*)(\d*) (\d+):(\d+) (\d+)
(\d+)\] \[(\d+)\] (\d+) (\d+) (\S+)/o) {
to following
if($LINE =~ / --- \[(\d*):(\d*) (\d+):(\d+) (\d+) (\d+)\]
\[(\d+)\] (\d+) (\d+)/o) {

[ns] Please help me with IDE
Hello, I'm new to use ns2, so I'm using Eclipse IDE with CDT plugin in order to have a graphical support for writing the code(I have find another faq about this topic), but I'm not able to create a project because I don't know which files I have to include about ns2. I give you some details: I have to develop another Zigbee layer, so I have to include files in wpan_zbr folder which are MAC 802.15.4,and thus my question: which other files I have to include in my project in order to develop another layer in ns? Please if someone can help me I'll appreciate very much. Thanks and sorry for my bad english!!

[ns] Please help me regarding documentation
Hi users and friends, I want to know more information about NS2. Is there any material which can give more documentation about the statements used in NS2 program code ( both c++, TCL and their linkage) especially for addressing and AODV. I went through NS-Manual, Marc Greis Tutorial and NS by example, and also documentation generated by doxygen. In any of these, I am unable to find much elaboration about particular topic. So, please help me. Add more friends to your messenger and enjoy! Go to http://messenger.yahoo.com/invite/
Re: [ns] please help me | OK
Dear Mr. Wei, I think yes. This awk script for DSR routing protocol mainly. For other protocols like AODV, Tora you need to do some modification like changing ( $35 =="DSR") to the destination protocol like AODV if you simulate AODV ). To do the correct changes and modifications, I advise you to study the new trace file format, after that try to apply simple sinarios to insure everything is ok. If you face problem try do some searching in the internet, may you got a solution.

[ns] Please Help - UDP AdHoc Broadcast
Hi everyone I am very new to NS2 and ns2 manual is not user friendly at all. I need to be able to broadcast a single UDP packet at unpredictable moments(determined through the program logic). This broadcast is initiated by one of the 400 nodes present in the MANET Network and every other within-range node should be able to receive it (which I assume 802.11 protocol will itself care about which nodes should receive the packet and which don't according to their distance from the source(??)) If not forced otherwise I need to find a solution using pure OTCL script with no C++ code dealings. should I use a UDP agent and define a traffic source(?) and connect it to all other nodes? if not what? Thanks already

[ns] please help me about hierarchical routing
Hello everyone,
I am a student doing my project about routing with different address scheme.
Now I have encountered some problems when I try to implement DV routing
protocol in a network with hierarchical addresses:
1. The protocol can only be implemented on some nodes, rather than the
whole network. If implemented to all nodes, it will report the following
error info:
--- Classfier::no-slot{} default handler (tcl/lib/ns-lib
.tcl) ---
_o19: no target for slot 0
_o19 type: Classifier/Addr
content dump:
classifier _o19
0 offset
11 shift
2047 mask
1 slots
slot 0: _o20 (Classifier/Addr)
-- Finished standard no-slot{} default handler –
2. When implement the protocol on some nodes, the routing table size
of these nodes did change. However, there’s no trace of the type “rtprotoDV”
in the trace file. So I am really confused. If there’s no rtprotoDV packet,
how could the table size changes?
3.The chapter of hierarchical routing in the ns2 manual says the table
size would be smaller when hierarchical addresses are used, but the results
seem to be the same.
Since I am running out of time, it is very urgent. So I hope someone could
help me a little. Thank you all in advance.
Below is my ns2 script. Thank you very much for spending your time on my
problems.

[ns] Please help in plotting performance plot
Hi,
I am a new to NS2 and trying to simulate various routing protocols. I
followed many tutorial provided on internet.
I am using the below codes for simulating shortest path, distance vector
and link state routing and i need some help in this.
Queries:
1) Are the below code correct to perform routing.
2) If the codes are correct than how will i modify the code to change
the network load as in the code there is nothing mentioned about the network
load.
3) how shall i calculate the average delivery time of the packets for the
network using the trace files generated.
I know these are very simple queries but since i am new user and trying NS2
1st time so i am getting bit difficulties in finding the answers of these
queries. I am using ns2.34 version on red hat.
Please help me!

[ns] please help: problem with routing table ????
Hi all ,
To print the routing table I have followed this steps :
1)I went to the file aodv_rtrace.h and add this line
void print(Trace*);
2) I wet to the file aodv_rtrace.cc and add this fuction
void
aodv_rtable::print(Trace* out) {
sprintf(out->pt_->buffer(), "P\tdest\tnext");
out->pt_->dump();
for (rtable_t::iterator it =rt_ begin() ; it != rt_ e();it++) {
sprintf(out->pt_->buffer(),"P\t%d\t%d",
(*it).first,
(*it).second);
out->pt_->dump();
}
}
(print is the function which print the routing table in the trace file )
3)recompile ns2 by typing ./configure then make install in the
~ns-2.29 directory because i'm using ns2.29
so then i must see in my trace file the routing table printed
but I don't see this routing table and i don't know why ?
So please help me it's vey important
i have attached you my 2 files
aodv_rtable.cc and aodv_rtable.h
Thank u a lot in advance

[ns] Please help mo for SMCC on NS
hi to all! I am a newer about NS. my interesting is multicast congestion control. I have some problems when I run SMCC[Gu-In Kwon and John W. Byers. Smooth Multirate Multicast Congestion Control.IEEE INFOCOM 2003] I have downloaded SMCC source codes from the writer's websit: http://cs-people.bu.edu/guin/smcc.html. When I run the simulations, there are several problems, maybe the reason is the version I used is 3.2 which is differented from the writer's. Could somebody give me some advice that how to modify the codes in order to run simulations successfully in NS 3.2? The Problems is as follows: 1、If I replace "TCP-sink.h" and "TCP-sink.cc" with the website provioded, the error log in "make" procedure is : "tcp/tcp-asym-sink.o:tcp-asym-sink.cc:(.text+0x30d): undefined reference to `Acker::update_ts(int, double, int)' tcp/tcp-asym-sink.o:tcp-asym-sink.cc:(.rdata$_ZTV11TcpAsymSink[vtable for TcpAsymSink]+0x34): undefined reference to `DelAckSink::reset()' collect2: ld returned 1 exit status make: *** [ns] Error 1" So I retain the inherent codes in NS 3.2 instead of raplacing them. 2、I put "smcc.h" and "smcc.cc" in the directory "\ns-allinone-2.31\ns-2.31\mcast" When make it , there are some error information as follows: mcast/smcc.cc: In member function `void SmccAgent::warmup()': mcast/smcc.cc:123: error: ISO C++ forbids initialization in array new mcast/smcc.cc:124: error: ISO C++ forbids initialization in array new mcast/smcc.cc:125: error: ISO C++ forbids initialization in array new So I modified the codes ： 123 send_timer_ = new SmccSendTimer[Max_smcc_Layer](this); 124NoFeedbacktimer_ = new SmccNoFeedbackTimer[Max_smcc_Layer](this); 125bcl_timer_ = new BclTimer[Max_Bcl_Layer](this); to: SmccSendTimer *send_timer_[Max_smcc_Layer]; SmccNoFeedbackTimer *NoFeedbacktimer_[Max_smcc_Layer]; for(int kk=0; kk

Re: [ns] please help: problem with routing table ????
One way to print routing table in aodv in ns-2.28 would be the following..
(Assuming you have basic familiarity with C++ and any general routing
table structure)
1. Declare a function - rt_display(int node_id) as a member of class
aodv_rtable (in file aodv_rtable.h)
node_id is an argument which you can pass while calling the function and
later print it along with the routing table so that you know which node is
printing it's routing table.
2. Define the same function in aodv_rtable.cc. Inside the function
rt_display(int node_id), print the fields of rt->rt_dst, rt->rt_nexthop
and so on.. (all the fields that are of interest to you). To see how to
access individual entries of the routing table, take a look at rt_lookup
function.
3. From an "appropriate place", call this function. ( one place I would
suggest is from rt_update in aodv.cc , call rtable.rt_display(index). This
would dump the routing table whenever there is an update to the routing
table )
Then, recompile ns with make and try running your simulation.
Thanks,
Kanthi

Re: [ns] please help .. "*** NOTE: no connection pattern specified."
Dear,
This error occurs when you specify an external file to read from tcl script.
I think that either you have given the wrong path of your file or you have
done any spelling mistake.
Recheck this.
Furthurmore if "setdest" is you movement pattern file and you are using "
./setdest " then you must first ensure that both movement pattern file and
your tcl script should be in same directory
regards,
Yasir

[ns] Please help me!About sctp multihoming on wireless
Hi
I tried to simulate sctp on ns-2.28.
I have readed the paper on
http://www.lib.ncsu.edu/theses/available/etd-05162005-094333/.
According to The FAQS of the paper , I modified two parts.
1.$ns_ node-config -wiredRouting OFF
2.commented out the line
//Tcl::instance().evalf("\%s no-slot \%ld", name(), cl)
in classifier.cc
I created multihoming nodes(mobile node) in WLAN .
while i execute ... it can not work.
Then I configure the mobilenode using $ns_ node-config -multihome-core \
and
$MH addif $MH_if0
$MH addif $MH_if1
instead of
#$ns_ multihome-add-interface $MH $MH_if0
#$ns_ multihome-add-interface $MH $MH_if1
But Segmentation fault(core dump) occur.
Before I have successed ... when use mobilenode without multihoming .
But when add multihoming,the data can't be transfer.
Please help me.
Thank you very much.
My script is as following.

[ns] Please help: Energy AWARE AODV. Power-aware Routing Protocol
Hello guys, I badly needed your help. This is urgent. I have posted already some questions regarding my problem but there was no reply. http://mailman.isi.edu/pipermail/ns-users/2007-April/059757.html http://mailman.isi.edu/pipermail/ns-users/2007-April/059765.html Is there someone who did a study before about ENERGY/POWER-AWARE Routing Algorithm? Can you give me some sample codes or links where can I get an energy-aware routing algo (for my reference)? Or a detailed discussion HOW did you make the code and implement it in ns-2. PLEASE... Hoping for replies. Thank you very much. xyza
Re: [ns] please help me to install IEEE 802.11e HCCA.
Hi BJ To make the number 4 of process you should make the following: you should save the patch in a file archive for example into the /home and then you go to the terminal and executing the following command: cd /home/ns-allinone-2.29/ns-2.29 when you make this, you enter to working directory of ns-2.29, then, from this working directory you should search the patch that you saved in /home and apply it by executing the following command: gzip -dc /home/ns2hcca-2.29-060823.patch.gz | patch -Np1 then, from the working directory of ns-2.29 you should execute the following commands: ./configue make clean make best regards Jorge Bustos ByungJoon Oh wrote: > > > > Dear All NS-users, > > I try to install ns2hcca source code decribed with website: > http://info.iet.unipi.it/~cng/ns2hcca/ > However, I can't install about that. > As described this website, I have followed the precedure of installation. > But, I can't make sense of Number 4 of process.

Re: [ns] Please help me to solve my issue in ns2
Hi,
I don't think you want to classify packets in mac layer. Instead, you want
your packets to be submitted to aodv. Thus, in aodv.cc, you need to identify
your packets in AODV::recv(Packet *p). In fact, as you know, all packets first
arrive at such a recv function in any layer. So if you want to do anything
about your packets, it should be in this function.
Then how to identify your packets
you need to register your packet header in common/packet.h
then you can set hdr_cmn and use it to identify your packets and do something.
hdr_cmn *ch = HDR_CMN(p)
when you send a packet, set the packet type as yours,
when you recv it in aodv
if(ch->ptype() == PT_YOUR_TYPE) {
recvMYPACKT(p); //change to execute your code instead of recvAODV(p)
return;
}
Detailed how to register your header can be referred to
Implementing a New Manet Unicast Routing Protocol in NS2
see the "needed changes" part.
BTW, how to suppress duplicate packets I have sent. I do not want to read
aodv code if you already know.
Best,
Pei

Hello Daniel
I hope that you are fine. I need your help to resolve my problem in ns2.
Basically i am using AODV.cc and as you know that AODV has many types of
packets like HELLO, RREQ etc. I have declared my own packet header in AODV.cc
and i used it for unicasting. Now the problem is that when i send my own packet
from source to destination in AODV.cc then first this packet is received in MAC
802.11.cc file in the recv_timer() function and then in this recv_timer()
function all the packets are classified. For instance if the packet is Control
like RTS/CTS/ACK then recv_timer() call functions like recvRTS() etc etc. and
if the packet is data packet, as Hello or my own packet then it just check
whether it is data packet or not and just call the recvDATA() packet in
mac-802.11.cc and then this function send packet to upword layer to recv()
function that is present in AODV.cc file. Then further action is taken place
and packets are being dropped there.
Now my problem is that when i send my own packet from particular source to
destination then at the mac layer all the nodes that are in the communication
range will listen this packet and discard them at the mac layer (control
packets) but if the packet is data packet, in the mac layer it will not
classify the data packet, instead it will just check whether it is a data
packet or not and then forward it to upper layer.
What i want to do is that at the mac layer, in the recv_timer() function, the
mac layer should classify the data packet and if it found that at the mac layer
that this is a data packet and of type HELLO or RREQ then discard them or if it
is my own data packet type then forward it to upper layer.
I hope you understand my question.
Thanks in advance.

I shall be very obliged if you will help me out .Also , I am attaching a document regarding the way I want the output statistics , this paper contains information about the Denial of Service attacks but nowhere the scripts have been provided for simulation. Desperately awaiting your kind reply. With best regards. Ashutosh Srivstava Send instant messages to your online friends http://in.messenger.yahoo.com

Re: [ns] Please help me I want tio monitor queue size on lan
Hi all, I am trying to measure the average queue delays over all the nodes in an ethernet setup under ns. Since the ethernet setup is not a typical link to link setup but a shared medium one, how should I be measuring the queue delays ? thanks for any help, Prince
[ns] Please help me to implement Multipath Source Routing (MSR)Protocol in NS2
hello, I want to implement a new protocol Multipath Source Routing (MSR) is an extension of DSR (Dynamic Source Routing) that incorporates the multipath mechanism into DSR. MSR is an adaptive routing for ad hoc networks. It considers the two fundamental issues in its design. MSR may adapt to topology changes by retaining the route discovery and route maintenance mechanism of DSR. In addition, MSR employs a probing-based load-balancing mechanism. Kindly send me the C++ source code of MSR protocol and the procedure to add this protocol in NS2 for implementation. Thank You

[ns] Please help me: A problem when I get Instance of Routing Agent AODV????
HELLO,
I want to reach a memeber variable in aodv to modify in Mac.
For this reason I get instance of Routing Agent AODV as explain in website
Veiled how I recovered this variable:
In file mac_802-11.h I added:
#include "aodv/aodv.h"
In file mac_802-11.cc I added:
void Mac802_11::recvDATA(Packet *p)
{
.
AODV* aodvagent;
int i= index_;
char command[256];
sprintf(command, "foreach aodvagent [Agent/AODV info instances]\
{\nif { [$aodvagent id] == %d} {\nset i $aodvagent}}\nset t $i\n", i);
Tcl& tcl = Tcl::instance();
tcl.eval(command);
const char* ref = tcl.result();
aodvagent = (AODV*)tcl.lookup(ref);
.
}
but when I execute the script tcl, I found
ns: foreach aodvagent [Agent/AODV info instances]{
if { [$aodvagent id] == 5} {
set i $aodvagent}}
set t $i
: wrong # args: should be "foreach varList list ?varList list ...? command"
while executing
"foreach aodvagent [Agent/AODV info instances]{"
and the execution stopped.
Please Where is the problem.
Thank you in advance

[ns] Please, help is needed on specifying the RXThreshold when using the Ricean fading model
Dear all, Please have anybody used the Ricean fading model in wireless simulation? is so, how you have calculated both the recieve threshold and the carrier sense threshold to determine the transmit range? is it correct to use the threshold.o utility in ns-2 with TwoRayGround as the propagation option since it the long scale fading used with the Ricean? please answer me, I am waiting any hint from you. thanks alot, gaby - You rock. That's why Blockbuster's offering you one month of Blockbuster Total Access, No Cost.

[ns] Please Help - wireless nodes - packets dropping problem when more than one agent is attached
Hi,
I'm new to ns2. I've been trying to simulate a wireless scenario in which a
mobile node sends data to another mobile node. I attached two udp agents
with node0 with cbr traffic for both of them. Then i attached two null
agents to node1 to receive the data. Both the agents are started at the same
time and made to run simultaneously. While I do so most of the packets get
dropped. Is there any problem if i attach two agents to a wireless node and
make them work at the same time?
The following is my tcl code:
