[ns] new 80211 - Packet Loss

Hello, I know that in DCF, the MAC tries to send a packet 7 times before giving up. Using the new 80211 code from Mathieu Lacage, how can I know for sure when a packet has been lost (i.e. the sender gave up sending it) ? Thanks. Best Regards, Pedro Fortuna

Re: [ns] how to add delay factor bytes per second

Hi, Can't you use a time delay instead ? Maybe you can implement a custom queue which adds that overhead. It should not be so hard to do it if you create a subclass of Queue. Regards, Pedro Fortuna INESC Porto On 8/3/06, Muth S [EMAIL PROTECTED] wrote: Hi all, I need to add a delay

Re: [ns] VoIP traffic Simulator

Hello, I've been using Application/Traffic/Exponential as a traffic generator on top of Agent/UDP. It's not perfect, because, for instance, I specified 8Kbit data rate, but often I only see 5 or 6Kbit/s passing through... but maybe i'm doing something wrong Pedro Fortuna INESC Porto On 8/4

Re: [ns] send_time = Now or Scheduler::instance().clock();

Actually, I think it is exactly the same thing, as Now is defined as a Scheduler::instance().clock(). You may even see in some places the macro CURRENT_TIME. They are all macros for Scheduler::instance().clock(). Regards, Pedro Fortuna INESC Porto On 8/10/06, Bie New [EMAIL PROTECTED] wrote

Re: [ns] window_ TCP parameter

It's in packets, almost for sure. I believe there is another parameter named winbytes_ or something similar, which enables you to define the window size in bytes. Regards, Pedro Fortuna INESC Porto On 9/13/06, Renata Vidal [EMAIL PROTECTED] wrote: Hi, Anyone knows if window_ parameter
