Re: [ns] general question about delay

Hi,

I dont know about DSR protocol. I think delay can be add to your simulation by 
using this formula. delay = number of bits / link bitrate . For example, if you 
can find out the number of bits that you want to transmit and the link bitrate. 
You can simulate the transmission delay. Then, the delay value can be use to 
schedule the event to send the next packet. 

I might be wrong. Hope others who are knowledgeable can clear this up.

Thank you.

Ben.

hi,

 i want to add a delay to or something that packet wait some time in a quequ 
before they recive can you help that how i will add delay in DSR or any 
protocol?

Please help me in new in real problem

Regards,

Hussain

[ns] general question about delay

2007-01-19 Thread ben

Hi,

I have two CBR traffic generator and receiver in my
simulation. Packets are generated at 32 kbps and on
ideal condition with a droptail queue. The receiver
should receive the packets at 32kbps.

I'm trying out the WRR packet scheduler. The
parameters are buffer size, the link bit rate
(bandwidth), scheduler delay and  a variable that
stores the sequence of which queue to be serve. The
parameters would simulate the queueing and the
transmission delay. In order to get 32kbps at the
receiver, I would adjust these parameters. Then, I
would repeat the simulation with different data rates.


Am I doing it right? Any suggestion on literature or
reference that should I refer on this matter.

Thank you very much.
