Thanx again for the reply.
In the following proc, where it sets ackRcvd_, there I will set
acknowledgment nos. of the packets that it will receive. Where as, 'sntp'

Ah!, I see now - I thought you wanted thin
Yeah, I made mistake in deriving from the class. I changed it to Agent now.
The new code is here. But basically I want to change this variable in Tcl

In C++

This should give you the number of bytes transferred during the
simulation. Bandwidth would be a property of the link over which this
connection is made.

Hello everybody
Can anyone help me how to find energy consumption at MAC layer in a wireless
network ( old trace wireless format) and take results to xgraph to have a graph
with awk script ?
Thanks for help

Hi,
You can simulate a perfect MAC layer with:
$ns_ node-config -macType Mac

Hello
I am trying to calculate throughput over a TCP connection for different
upper bounds on the sender window size. The methods used are as following.
For binding the sender's window:
$tcp set maxcwnd_ 3
To calculate the bandwidth:
set bw [$sink set bytes_]
puts "[$tcp set maxcwnd_] [expr $
Hello,
I need to run multiple iterations of my simulation (in the order of
~100). I'd rather not re-run ns2 for each iteration since doing so
requires reestablishing the network and initializing ns2 each time.
Instead, at some time t, I'd like all traffic in the network to
disappear. And at ti

Thanx for the reply Abhitjeet. Here is the code in Tcl. Of course there are

Hi,
I am simulating a network layer protocol of the wireless ad hoc network, and I
would like to target on the network layer performance and assume a perfect MAC
layer in which there is no collision, packet drop or buffering delay. Can I do
this by simply making the following modifications in
regarding your questions, the answer is "yes" to all.
However, there is a much faster way to make temporary changes to the otcl
lib, especially useful when debugging and redefining a standard procedure:

Hi ns-users,

I am a newer. When I use nrlolsr as adhoc routing protocol for
