Hello Vivek,
Maybe you're mxing up some things.
>From what you write I conclude that what you actually might want to do is
"intercept" (=prevent that it is receptioned on a higher layer) a packet,
rather than just "capture" (=get a copy of its content) it.
If so, then Wireshark is not the tool to do it.
And I doubt that there is any tool for doing this easily.
If you want a machine that stands in a transmission path and adds delay (or
other perturbations) to packets, then what you need is probably a PC with
two network interfaces, capturing from one, applying the perturbation and
then playing back onto the other.
Some comercial solutions based on this principle exist: Netdisturb, Internet
Simlulator, ...
Regards,
Lars Ruoff

Respected Sir/Madam,
I am student of Pune University, doing project on WAN
Emulator.
I have following query :
wireshark uses the libpcap library which gives the copy of
packet.
So, How to capture the original packet at data link layer or
network layer ?
We want to experiment the behavior by adding delays to those
packets, and
that is why we want the actual packet and a copy of packet
wont serve purpose.
Thanks in advance.
