[ns] getting error while recompiling ns-2.. help pls!!

2010-11-30 Thread chithra17 


Hi friends,

I tried attaching the 802.11e patch (from
http://www.tkn.tu-berlin.de/research/802.11e_ns2/) to ns2.34 version. after
i made the required modification I typed ./configure then make, make
clean am getting the following error.. 

Makefile:66: *** commands commence before first target.  Stop.
 
I don't know where am going wrong. Does this patch works only on ns2.28?? or
can i work with ns2.34 also??
Please help me friends..

Thanks,
Chithra

2010-11-30 Thread Hosseini Nezhad 

Dear

In wireless environment I have user DSDV as routing algorithm.
I have 2 nodes and I have set Packet Transfer at 1.0 Second of simulation.
But the packet transefer start at(almost) 2.80 second of simulation.

On the other hand when I have use AODV as routing protocol, packet
transfer start on time.

Would you help me on this problem?

Re: [ns] Counting hops

2010-11-30 Thread Dhara Buch 

Hello,
I want to do brodcasting for a packet. I am creating node objects of 
Agent/Messagepassing type. I want to keep a variable for storing the number of 
hops a packet passes i.e. I want to store hop count value for each packet. What 
is the appropriate method, where should I write the code for increment 
operation? 

   Thank you,

[ns] how to set threshold of packet amount before forwarding ?

2010-11-30 Thread shimizu-hxd 

Hi all,

  I want to make a multi-hop wireless network system, in which
  relay nodes store received packets untill size of buffering packet
  reaches fixed thresold. And when buffering size reaches thresold,
  relay nodes starts to send packets to next-hop.
  So, I want to know how to set thresold of buffering packet size
  before forwarding.
  Are there any way to set thresold like queue limit size
  (sentence like $ns queue-limit $n1 $n2 10)
  Or should I extend some modules?

  This may be rudimentary question, but please help.

Regards,
Hideyuki Shimizu
