Re: [ns] How can i measure the bandwidth in use?

I am not sure if there are other cleaner techniques to do this, but one of the ways can be attaching a LossMonitor agent to the other side of the link, and periodically keep recording number of bytes received during a small interval. This will give you the b/w in use. Total bandwidth of a link can

Hi, I am trying to study packet loss with AODV in the ns-2 implementation. I wanted to know how I can detect when a packet is dropped (i tried to analyze trace files but I could not decipher from them). Does anyone here know where in the implementation I can look for the details of when a pac

Hello Desai, I don't actually understand the sequence of steps you said. But in my view at the end of all the changes, some how the class definition related to "Queue/WFQ" is missing in your installation. In order to verify this run the following command inside the ns-2 directory and see if y

Re: [ns] Delaying Transmission of Sending Node

Hi all, I am fairly new to implementing protocol modifications in ns-2. Currently what I want to do is to delay transmission of packets for a transmitter for a specified period of time. I have already grabbed this period of time from the incoming packet, but I am unsure where to implement this

Hello there, I get a stupid question. If bandwidth is 10Mbps, and each flow has rate of 16Kpbs. How many flows are need for 10Mbps ? 10 M * 1000 / 16 = 625 Or 10M *1024 /16 = 640 Regards, Newbie.
