channel model for mobile multi-hop wifi networks
http://comments.gmane.org/gmane.network.simulator.ns3.user/20404
<pre>
Dear ns3users,
could anybody recommend me a channel model for the simulation of mobile
wifi ad-hoc networks? Is out there a particular example I should rely on?
Thanks in advance,
Marco

Protocol value in FiveTuple
http://comments.gmane.org/gmane.network.simulator.ns3.user/20402
<pre>I have a simple network 4 nodes with onoff application. There are 2 UDP
flows instantiated using UdpSocketfactory and 1 TCP flow instantialted
using TcpSocketfactory.
I am using flowmonitor and flowstats to print out the flow statistics (see
appended code snippet). Everything works fine except that the protocol
field
in the fivetuple is empty (See attached results) which I gather should be
17 for UDP and 6 for TCP.
When I create a flow using the UDPSocketfactory, isn't the protocol field
set to UDP?
My apologies if this has already been discussed before.
Thanks.

Disable Aacknowlegment in MAC
http://comments.gmane.org/gmane.network.simulator.ns3.user/20400
<pre>
Hi to all,
I was trying to provide a new mechanism for reliability in MAC layer,
therefore I needed to disable the ACK packets and retransmissions in MAC
layer. I could disable retransmission by using :
Config::SetDefault
("ns3::WifiRemoteStationManager::MaxSlrc",StringValue("0"));
however I could not find any easy way to disable ACK packets. is there any
easy way to do that?
Best regards

}
LENA of NS3 support only Ipv4??
why do not support other protocol ?

basic question regarding GetTypeId
http://comments.gmane.org/gmane.network.simulator.ns3.user/20398
<pre>Hello all,
I have been learning ns3 the last 1-2 months and I believe that I have
reached a level where I can solve most of my problems simply by browsing
the doxygen documentation.
But today I came up against a strange ns3 behavior, which can not be solved
solely by doxygen, so I would be glad if anybody offered some help.
What is the method "GetTypeId" supposed to return?
For example go to the first example (where you create 2 point to point
devices) of the tutorial first.cc and add the following line right
before Simulator::Run ()
std::cout << "The device is " << devices.Get (1)->GetTypeId() << std::endl;
The program will return
The device is ns3::NetDevice
instead of
The device is ns3::PointToPointNetDevice
as one might expect.
the devices are created by the PointToPointHelper, which according to its
source file (line 229) found here
http://www.nsnam.org/doxygen/point-to-point-helper_8cc_source.html#l00225
creates "point to point net device" instead of "net device".
Thus, the "GetTypeId" should return what is mentioned in
PointToPointNetDevice::GetTypeId<http://www.nsnam.org/doxygen/classns3_1_1_point_to_point_net_device.html#a045e48d24e615c82db1a9a952a9725b5>()
found in the following link
http://www.nsnam.org/doxygen/point-to-point-net-device_8cc_source.html#l00040
and more specifically at line 42 ( static TypeId<http://www.nsnam.org/doxygen/classns3_1_1_type_id.html>tid =
TypeId <http://www.nsnam.org/doxygen/classns3_1_1_type_id.html> (
"ns3::PointToPointNetDevice"))
How can this behavior be explained?
thanks in advance to anyone who will dedicate his/her time to help me

......
//function call configmovements(mobnodes, .....)
}
void configmovements(nodecontainer mobnodes, .....)

Issue in sending internal traffic in Emulation mode
http://comments.gmane.org/gmane.network.simulator.ns3.user/20392
<pre>Hi All,
I'm using following topology in emulation mode:
Laptop-1
Now the program is running in Emulation mode. In this, I can
successfully transfer the packet from Laptop-1 to Laptop-2. But if I try to
generate and send internal traffic from (say) Node N4 to node N6, then it
doesnt send any packet. It just do 'ARP' request and response from N4 to N6
and back. But no transmission is done. But if I use "Simulation" mode then
I'm able to send packets from node N4 to N6.
So, I need your guidance here. At first, could you please let me
know whether I can send internal traffic in Emulation mode or not. Second
thing is how to do it. Please let me know. I need this thing at very urgent.
Thanks & regards,
Deep Singh.

how to use "double BasicEnergySource::GetRemainingEnergy (void)" to get the remaining energy after the user defined function.
http://comments.gmane.org/gmane.network.simulator.ns3.user/20389
<pre>Hello sir
I am trying to find energy consumed in finding the shortest path(static).
Energy module used is basicEnergySource.
When generate traffic is called energy is consumed due to packet sending,
but our user defined function has no impact on battery energy.
Please help me with this problem.
Please find the attachment for the program.

<pre>adding two emu to pgw and ue node respectively, I want to transmit real
data in lte network .but now when i add an emu to pgw ,I try to receive and
send data only using the emu ,nothing else i used ,however, the question
is when i don't add l"teHelper->Attach (ueLteDevs.Get(0),
enbLteDevs.Get(0))",the emu work very well , when I add it ,I get the data
slower and don't get the data for a while,and a moment later ,I get
again,finally I can't get the data in the physical host;

<pre>Hello,
I am a EE grad student and I am trying to learn NS 3 to do some
simulations. My background on programming is bounded to C++ and somewhat
OOP. No python experience. I have read the Ns-3 tutorial however I could
not proceed in writing a whole project.I wonder how you first started to
learn and managed to accomplish writing a whole project successfully.I
would appreciate if you share your experiences.Thanks

it's pretty the same for all the other flows .
Why are my packets lost , and how can I have the throughput different from

Any idea please ?
Thanks a lot .
How can I have

error while running my program in ns-3.17
http://comments.gmane.org/gmane.network.simulator.ns3.user/20379
<pre>Hello All,
here i attached my simulation file,while running it in ns-3.16, it's
working properly but when i am running it in ns-3.17 it's giving me error
msg="UEs need to have IPv4 installed before EPS bearers can be activated".
i am not getting how to fix it. if anyone know about it please tell me
which saves my much time. Thanks..

sinr, tbs,qci stats calculations and loss models appplicable
http://comments.gmane.org/gmane.network.simulator.ns3.user/20378
<pre>Hi,
All the propagation loss models (PLM) are single frequency and only provide computation of loss at a certain distance for that frequency, on the other hand, the spectrum propagation loss models (SPLM) provide calculation of TX/Rx Power Spectral Density.
Question 1: does it implicitly follow that PLMs are strictly for use with Uplink and SPLMs for use with Downlinks???
Question 2: Given the above situation, what would be the correct way to compute Qci, Sinr, Tbs etc...just take them from MAC stats??? In fact, the more analytical way should be to use different methods when one has access to spectral density and when only to RxPower (TxPower - comptedLoss)...is this correct, if not, then please tell me which is the right way then...
With Regards,
madan

How to schedule Flow Monitor to get throughput per second?
http://comments.gmane.org/gmane.network.simulator.ns3.user/20369
<pre>Hi,
I have a network that is simulated for 20 seconds, and I want the
throughput each second so that I can plot Mbps over seconds. Below is a
snippet of the flow monitor function, and at the moment it calculates the
throughput over the whole simulation i.e. for 20 seconds. Basically, how do
I schedule the flow monitor so that it calculates for each second?
Help is appreciated!
FlowMonitorHelper flowmon;
Ptr<FlowMonitor> monitor;
monitor = flowmon.InstallAll();
// monitor = flowmon.Install(apNodes);
Simulator::Stop (Seconds (20.0));
AnimationInterface anim ("CSMA_Anim.xml");
anim.EnablePacketMetadata (true);
Simulator::Run ();
monitor->CheckForLostPackets ();
Ptr<Ipv4FlowClassifier> classifier = DynamicCast<Ipv4FlowClassifier>
(flowmon.GetClassifier ());
std::map<FlowId, FlowMonitor::FlowStats> stats = monitor->GetFlowStats ();
std::map<FlowId, FlowMonitor::FlowStats>::const_iterator i;
for (std::map<FlowId, FlowMonitor::FlowStats>::const_iterator i =
stats.begin (); i != stats.end (); ++i)
{
Ipv4FlowClassifier::FiveTuple t = classifier->FindFlow (i->first);
NS_LOG_DEBUG ("Flow " << i->first << " (" << t.sourceAddress << " ->
" << t.destinationAddress << ")");
std::cout << "Flow " << i->first << " (" << t.sourceAddress << " -> " <<
t.destinationAddress << ")\n"; std::cout << " Tx Bytes: " <<
i->second.txBytes << "\n";
std::cout << " Rx Bytes: " << i->second.rxBytes << "\n";
std::cout << " Throughput: " << i->second.rxBytes * 8.0 / 20.0 /
1024 / 1024 << " Mbps\n";
}
bool enableFlowMonitor = true;
if (enableFlowMonitor){
monitor->SerializeToXmlFile ("CSMA_AP.xml", true, true);
}
