thx for ur kindness,
i want to work on "video transfer over wireless mesh network on 802.11s" so 
i should have some changes on 802.11s protocol to improve

trace tr file

hi 

i generated tr file in ns3 but  because format of this file is different 
from ns2 I can not write AWK script for it.
how can i write AWK for this tr file? 

tnx

Hi Tracy,
I dont understand what you  mean by "it is kind of pre-set module in the 
whole 11Dots part". Sent mails for Andreev but no replies as yet. So am

WLAN Mac contention values

Sameer — 2013-05-21T07:12:07

I want to get these values in my simulation of a 802.11 based network


   1. The time a node spends in *receiving* a packet
   2. The time a node find the channel to be *occupied*
   3. The time a node spends in *backoff* coz if finds the channel to be 
   busy

I want to calculate these values during a particular time period... say T ( 
10 seconds )

Any ideas of how this can be acheived will be very welcome

with regards,

Hi Solmaz

First of all you need to get a good understanding of 802.11s in general and 
then you will want to have a look at its implementation in NS3

You can find some valuable information here.

What particularly are you planning to doin 802.11s?

SNR in MAC layer

Sheena — 2013-05-21T05:45:31

Hey everyone..
I have added the SNR tag in yans-wifi.cc.Can I read that value in 
sta-wifi-mac.cc? If yes,then how?
Please reply.

Thanks

Re: Multiple Roots in HWMP

Tracy — 2013-05-21T05:08:46

 As far as I can see, it is kind of pre-set module in the whole 11Dots 
part. And I've thought of the same as you, we may need further assistance 
from Kirill Andreev, since I'am not sure if modification of the code will 
affect the function of broadcast, multicast or something else in 
Mac48Address module.

Re: external library option specified too soon

Andrew Beussink — 2013-05-20T23:30:05

I added methods to my application to accept the keys they need, and
generate them when I create and setup the nodes in my script.  I put them
in a map so I can look them up by identifier.

Re: calculate the coverage

Konstantinos — 2013-05-20T23:03:53

I have answered that in my first post. If you assume you have a comm.range 
250m, then using the grid allocator, position 100x100 nodes every 25m.

Re: Phy Rate

Konstantinos — 2013-05-20T22:17:52

You have to first get the NetDevice, then the WifiRemoteStationManager 
object and from that call the GetMode().

e.g.

assume you have a pointer to a node
Ptr<Node> node;
Ptr<WifiNetDevice> dev = node->GetObject<WifiNetDevice>();
Prt<WifiRemoteStationManager> manager = 
dev->GetObject<WifiRemoteStationManager>();

Then you will be able to get the mode
WifiMode mode = manager->GetDefaultMode();

or with any of the following methods depending on what you want to get

WifiMode <http://www.nsnam.org/doxygen/classns3_1_1_wifi_mode.html> 
GetAckMode<http://www.nsnam.org/doxygen/classns3_1_1_wifi_remote_station_manager.html#a1ced2a0f870adf44415439f9e9f1a166>

Re: calculate the coverage

Konstantinos — 2013-05-20T20:45:39

Follow the same principle in your scenario.
You know your total area and you can divide it in the patches (basically 
iterate for every meter x,y). Are your 'active' nodes change over time? 
If not, then you can do it only once, if not you have to do it every time 
the list updates.

Somewhere (either in your script or in you protocol) you have the list of 
active nodes. From NS-3 you can get their position and calculate the 
distance for each points of your 'patches'. If the distance is less than 
the comm.range then this point is covered.

manel — 2013-05-20T18:20:37

please kanstontinos help me : 

i have find this rule used in ns2 in one publication :
To measure coverage, we divide the entire sensing region into 1m×1m 
patches. The coverage degree of a patch is approximated by measuring the 
number of active nodes that cover the center of the patch.

so i must do like this

Hi 

        Does the function Assign(NetDeiceContainer c) of the

If not what does Ipv4InterfaceContainer interfaces = address.Assign

crypto ++

Haitham — 2013-05-20T16:23:48

Hi, 

I would like to install library crypto ++ for the implementation of Diffie 
Hellman exchange and AES encryption between a UDP server and UDP Client. . 
I have two questions:

1. How to install library in NS3 
2. How to call for example AES cryptosystem function from the library to ns3

I really appreciate if any one have a tutorial describe me that issue. 
Also, i am flexible if any one has an alternative solution to use 
encryption in Ns3. Many thanks


Kind regards,

Haitham
