1. There is a file source that frames data packets for the test_demo. This is part of a transmitter USRP.
2. I have another USRP as receiver that sends an ACK upon reception of data packets to the transmitter.
3. Start sign is a threshold value. If the packet information (calculated by some method) exceeds this threshold, transmission starts and upon receiving an ACK stops.
4. I change this threshold value for every new iteration and count how many packets were transmitted before receiving a success ACK.
I can do this manually for every iteration but how to automate it for say some 1000 iterations?
I hope it explains everything.

Q1: What do you mean by "participates in data transmission process"?
Does it just send out what it receives, or insert any new data?
Q2: For "upon receiving an ACK":- from where the ACK will comes from,
from upstream, downstream, or somewhere else?

If I understand you requirement correctly, you need a block that
continuously getting input from somewhere.
This input contains "start sign" and later followed by "ACK".
Upon receiving "start sign", this block will pass through all it
receives to its output port.
Upon receiving "ACK", this block will stop the pass through (means no
output), until it receive another "start sign" again.
Meanwhile, you want the block to count the number of inputs between
the "start sign" and "ACK", and use this number to plot graph.
Is this what you want? If yes then I am able to help you.
Let's clarify your requirements first.
