Hi,
  I want to add an additional field to the packet sent by a node and I 
want to do these changes at the LL layer, so where do I need to apply 
these changes i.e. in which files?

refer me to any documentation on this issue I would be more than 
greatful to you.

[siad lamri]

Hi Hiba,

The file  :  ll.cc  contains the implementation of the LL layer. To apply your 
changes, you modify the code of the following function :

sendto(Packet* p, Handler* h = 0);

Best regards.

[ns] wireless simulation about neighbor list

[Jack Yang]

 Hi every user,

 I simulate the wireless environment and I want to know the node's
neighbor table information.
 Where can I find this table information in the ns2 file ? i.e. which
file define this neighbor list info ?
 And then there is a question I thought is how can the ns2 keep the
table info. for every node ?
 Is there a  two-dimension array to memory the info. ?

Help me figure out this puzzle .
Thanks a lot.

[ns] real time issue

[Shan Gao]

hi,

I am trying to implement a wireless network on NS2.
I have a question about real time issue.
For example, each node in the network will process some data and this
process may need several minutes. But each node has very limited lifetime,
i.e. 1 minutes.
Then, in NS2, can the node finish its work? Does NS2 take this process time
into account?
thanks.

[ns] help required for power control

[Rizwan Ahmad]

Hi all,
 
I am new to Ns-2. I am interested in implementing the simple power
control scheme. i.e. RTS/CTS are transmitted at highest power and the
Data/ Ack are transmitted at desired power calculated with the exchange
of RTS/CTS. 
 
I have a feeling that it is not possible to do that using scripts?
 
If so I have to change the C++ code for which I am not sure where and
what changes to make?
 
Any hints will be appreciated and if someone has done please guide me.
 
Regards,
 
Riz

[ns] adding global variables in ns2

[Anuradha Sehgal]

I am working with NS-2.31 installed in cygwin.
I want to add some global variables in NS-2 or more specifically in
packet.h/packet.cc files.
I have tried it in packet.h, by simply adding it as we normally do in
C, but it gives errors like

multiple definition of my_var
first defined here  etc

here my_var is variable that i declared globally

Is there some different way of doing this, may be i am following wrong way
any help will be appreciated

thanks,
Anuradha Sehgal
