Re: [ns] how to get used-bandwidth of a wireless node in ns

2007-08-26 Thread Arturo Servin
I do not know if carrying a bandwidth value inside the flow is the best solution. Bandwidth as I see is data_transmitted/time. And time is relative, are you going to measure the bandwidth in the last second, the last minute, the last hour? So that why I think is not the best way. I would

Hi Joe, What u got is perfect. The ns doesn't just run the animation unless you use some code to do so as in exec nam wireless1-out.nam inside your tcl script or you can run nam wireless1-out.nam in the command terminal to run the the nam. http://crg.ee.uct.ac.za/~kamil/ Kamil On Sun,

Hi everybody I am running a wired-cum-wireless simulation. I am using rayleigh fading model. I observed that most of the TCP ACK packets are dropped. Is there any way to prevent these drops? Thanks in advance. Bhaskar Sardar

[ns] rayleigh fading model

2007-08-26 Thread bhaskar sardar
In a wireless simulation, wireless links are modelled using rayleigh fading model (fdT=.01). Do I need to insert an error module (e.g. drop packets at .1% rate) in the wireless link? How can I control the error process? I want to drop packets at 10%, 1% and .1% rate. Bhaskar Sardar
