I want to calculate the delay experienced by a packet in the downstream node at each node.
I would like to queue the arriving packets according to this delay.
I know that the delay.h file within NS2 contains the LinkDelay class which contains ,delay_ , which is the propagation delay, and the function txtime(p), which returns the transmission time of the packet.
Can I make use of this??
If so how can I calculate the delay experienced in the downstream nodes??
Also what about the time spent in the queue of the downstream node??
Well, you need to make awk script to calculate e2e delay. Follow below mention link for more information.

Thank you Arjav.
But its not the e2e delay that i require, but the delay that a packet would experience in the downstream nodes. And also i need to find this delay within C++, so that i can use it to queue packets accordingly .
As per I understand in ns2 there is no actual transmission of the packet as it happens in a real network .... the time it takes for a packet to reach a destination node .... or to calculate the round trip time .... it is all in the calculation considering the network parameters set in the simulation .... like the delay (or propagation delay) , bandwidth of the link ...and other parameters ... from there information packets are logically queued and like wise the queuing delays calculated depending on number of traffic sent .... considering or calculating the load in the downstream node and the time of transmission from the source code files and timer one may calculate the delay to be experienced in the downstream node.
