Hi everyone I've a topology in which some nodes can crash at run time. I'm using $ns rtproto DV to indicate that shortest path should be dynamically selected for file transfer.
To show that a node failed, i first tried to break all the incident links using $ns rtmodel-at 1.0 down $n(1) $n(2) in an appropriate loop. But when all the links to a node break, the script hangs, and the size of tracefile keeps increasing indefinitely. My guess is that NS2 keeps trying to find a path to "now isolated" node, even though none exists. Next I tried the following command $ns rtmodel-at 3.5 up $n(1) But the same problem occurs. Is there any way to break a node dynamically from topology and still use dynamic routing command in NS2?
