Dear Najma, Yes, you can get the node position whenever and where ever you require in ns2. For instance, when you declare the grid in tcl script and read the nodes initial position and movement pattern from a file, all these information is stored in the variables in mobilenode.cc file.
Now lets say, you are working in a routing protocol such as AODV or DSDV, there you can access the nodes position at any time instant by accessing the node object. After that you can give any condition which nodes to discard and which to not. Hope it helps.
