[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

Re: [ns] Please help me with this error
Hi, After adding a new protocol, you should type make than you should type make install as a root. If you do so, you won't have this error.

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.

I had been doing my simulations with a simple DropTail queue (by physically changing the link rate), but now, I am trying to see if I can apply a Token Bucket implementation to support multiple flows in a simple manner. I have been searching the mailing list to I can find pointers on getting started, as well as some of the ns-2 code (using a source browser), but I have generally only found references to Diffserv. I did notice that ns-2 does have a TokenBucket class implemented though. However, as far as I can see, diffserv seems to be the only one referencing this class. I came across this discussion on the ns users mailing list at http://mailman.isi.edu/pipermail/ns-users/2005-June/050699.html and the conclusion seems to be that using Diffserv with the queue mode being specified as DropTail was what a solution. My rate limiting simply requires token bucket mechanism: once I know the flow-id, I will have to do token bucket rate limiting myself. As per my understanding, diffserv is a class based qos mechanism, not a flow based one. Is looking into diffserv a good choice, or is there a better solution, or one that might be more appropriate for my requirements? I would appreciate any pointers that you could offer on this.

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.

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. (attached by pic file). please advice me to get a clue. Thank you in advance. Best regards, BJ,
[ns] Please help me about H.264 video transmission over IEEE 802.11e.
Dear All users, I like to test H.264 video transmission over IEEE 802.11e EDCA. However, I have got some error that is segmentation dump error. I don't know what is happening. If someone know where the performing test tcl file is, please teach me about that. otherwise, one who figure out this problem help me to solve out this transmission fault. let me learn about that. Thank you eveyone in advance. Best regards, BJ,
[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 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

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 -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Amin Irandoost Sent: terça-feira, 20 de Março de 2007 22:14 To: ns-users@ISI.EDU Subject: [ns] Please help me hi all in general how to capture return value of c++ function in tcl? -- Amin Irandoost

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!! Antonella, I suppose that you put your wpan_zbr folder in ns-allinone-2.29/ns-2.29 folder (so your folder is at the same level with other folders such as mac, routing, tcp, dsdv...). Then you can follow those steps http://mailman.isi.edu/pipermail/ns-users/2006-June/055973.html Good luck, -- Hai-Nam NGUYEN Elève 3A SLR, ENST Bretagne 2 rue de la Châtaigneraie 35576 Cesson Sévigné Site web: http://www.jcisio.com

[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 me to simulate attacks on the Ad-hoc networks
Dear all , For a project I need immediate help . Actually I have to simulate some attacks(on ns-2 )possible in the Ad-hoc networks: 1) sink-hole 2) worm-hole 3) Sybil attack 4) Rushing attack 5) Denial-of-Service and Flooding 6) Black Hole What these terms mean , for this purpose I am attaching a document containing basic terms and definitions .Please , it would be very kind of you if you can send me the simulation scripts for any of these (on ns-2) and also the method to run them .Also , let me know if there is any software to run ns-2 on Windows XP I am unable to simulate these attacks because I don't know how to use ns-2(rightnow I am running out of time). 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
