[ns] Rate of CBR Traffic ?
Hi aditya, when an event arrives suddenly for example the load of network is important, I will need to reduce the rate. at the beginning I do not have idea of the time of arrival of this event. thanks a lot Aditya [EMAIL PROTECTED] a écrit : Hii $ns at 1.0 $cbr set interval_ 0.05 This will change the rate at 1.0 time instance. You can change it any number of times. Bye. On 3/6/07, leticia bela wrote: yes that fix it statically. but how to dynamically change this rate during simulation (dynamiquely).

[ns] simulating new protocol under ns2
Hi,
I am a new user for Ns and i have a same problem like [EMAIL PROTECTED]
I well studied document Implementing a new MANET protocol in ns-2. I wrote
the same code in ns-2. that was compiled without error. I made all indicated
changes in ns-2 .
After wich i recompile ns-2 by typing make at ns-2.29 directory
it got compiled well. But when i try to use this protocol in my simulation
script, it produces the following errors.
