LENA supported only IPv4?

YW — 2013-06-19T13:19:03

Hi guys!

line 200 in [ns-3-dev\src\lte\model\Lte-ue-net-device.cc] 
LteUeNetDevice::Send (Ptr<Packet> packet, const Address& dest, uint16_t 
protocolNumber)
{
  NS_LOG_FUNCTION (this << dest << protocolNumber);
  NS_ASSERT_MSG (protocolNumber == Ipv4L3Protocol::PROT_NUMBER, 
"unsupported protocol " << protocolNumber << ", *only IPv4 is supported*");
  
  return m_nas->Send (packet);
}

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

basic question regarding GetTypeId

Foivos Michelinakis — 2013-06-19T12:52:39

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

Starting from the tutorials and the example codes you build step by step 
and modify the parts you need (add more nodes, different traffic). It 
requires hands on experience and a lot of try-n-error. For example try to 
solve these "lab 
assignments" http://www.nsnam.org/wiki/index.php/Lab_Assignments_using_ns-3
The code that you are going to use is mainly included in the tutorials.

is it wrong to pass a node container object as argument to a function:

nodecontainer mobnodes;
......
//function call configmovements(mobnodes, .....)

}

void configmovements(nodecontainer mobnodes, .....)

Re: How to compute propagation delay using ns-3??

Konstantinos — 2013-06-19T12:18:46

In NS-3 the *propagation* delay (at least for wifi) is either constant or 
random 
(http://www.nsnam.org/doxygen/classns3_1_1_propagation_delay_model.html)

If you mean the end-to-end delay between two nodes, you have to create a 
scenario to generate the traffic and measure the metrics you need.
there are examples in /examples/wireless folder on how to set up such a 
scenario and you can use Ns2MobilityHelper in order to make your nodes move 
according to the SUMO files (but I guess that you know how to do that since 
you said you have visualized them in NetAnim).

Hi rishu,

Did you get the answer for this question?? I am also in the same stage, but 
dont know how to proceed. Using ns2-mobility-trace.cc, but it just gives 
the positions of the nodes. How to make the moving nodes communicate??

Issue in sending internal traffic in Emulation mode

Deep Singh — 2013-06-19T10:20:09

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.

Narges,

            I am not sure what exact doubt you have about usage of 
TraceFadingLossModel and observe the fading fluctuation (c.f. Marco's 
remarks).

2. For what it concerns, I attach an execution trace of lena-fading.cc 
taken with fading loss model set to TraceFadingLossModel and PathLossModel 
set to FriisSpectrumPropagationLossModel...you can the fluctuation of the 
fading component in the execution trace file attached...

I hope it helps...

Re: How to use AMC model in a LTE/EPC configuration

Marco Miozzo — 2013-06-19T07:24:43

have you tried to move the nodes a bit?!?
They are concentrated in the origin with the eNB and therefore the fading
losses might be too low for producing any alterations.
Please consider to use a PositionAllocator (Disc, Box or Rectangle) in
order to have nodes with a reasonable distance from the eNB:
http://www.nsnam.org/doxygen/classns3_1_1_random_box_position_allocator.html

Lena-dual-stripe example is currently using the Box one.

marco.

Re: OnOffAplication error !

Junling Bu — 2013-06-19T02:29:45

hi, if you write " LogComponentEnable ("PacketSink", LOG_LEVEL_INFO);" , it 
means the output is  error message, warn message and info message.
But if you read code of PacketSink, this class only logs info message and 
function message.
so you could only get messages from PacketLink 
NS_LOG_INFO ("At time " << Simulator::Now ().GetSeconds ()
                       << "s packet sink received "
                       <<  packet->GetSize () << " bytes from "
                       << InetSocketAddress::ConvertFrom(from).GetIpv4 ()
                       << " port " << InetSocketAddress::ConvertFrom 
(from).GetPort ()
                       << " total Rx " << m_totalRx << " bytes");
or           NS_LOG_INFO ("At time " << Simulator::Now ().GetSeconds ()
                       << "s packet sink received "
                       <<  packet->GetSize () << " bytes from "
                       << Inet6SocketAddress::ConvertFrom(from).GetIpv6 ()
                       << " port " << Inet6SocketAddress::ConvertFrom 
(from).GetPort ()
                       << " total Rx " << m_totalRx << " bytes");
and maybe you treate these message as from OnOffApplication.

so if you want to see whole message from PacketLink, you can use 
LOG_LEVEL_ALL to replace LOG_LEVEL_INFO and then you will get what you want.

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

Any idea please ? 

Thanks a lot .

How can I have

Hi,

The Attach() method of LTEHelper installs a defause EPSBearer now and in 
order to do that you have to have an IPv4 stack installed.
So just move the attach part after the installation of the IP stack. See 
the examples of the lte module in the ns-3 version you are interested 
(ns-3.17).

Regards,
Konstantinos

Hi Marco,
 
Thanks for your quick reply. As you said, I introduced a fading model based 
on lena-fading.cc. However, still I cannot see any fluctuations!
I would appreciate it if you could have a look at my program attached to 
this email?
I am pretty sure that you can find the source of problem easily!
 
Thanks in advance,
Narges

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..
