I want to analyse as to how control and data transfer takes place to and from a particluar node. I want to know which are the external nodes trying to communicate with this particular node and how does this interaction take place. P.S:- I am quite beginner in ROS and have just started learning it.

Besides using rqt_graph, as suggeste by @nickw, you can also use the rosnode info command:

rosnode info /node_name
