I recently read NS2, which is used to simulate the networks. Now I want to see how my packets are sent to the server and received from the server. Though I can make use of ping command, I want a browser specific application, that allows me to visualize it.

Where I can see how the packets are sent from one node to the other node, as NS2 NAM does.

Is there any application that is able to do this? Correct me if I am wrong.

If your application uses the HTTP protocol, then you may use the Charles Web Debugging Proxy:

Charles is an HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet. This includes requests, responses and the HTTP headers (which contain the cookies and caching information).

Not sure what you're looking for but you can maybe try Fiddler at http://www.fiddler2.com/fiddler2/ , it lets you log all the HTTP traffic between your computer and the internet.
