Problem with simulation of AODV and DSR

The scripts available from Internet (from previous projects) are used for doing trace analysis in a very generic manner for some specific/ideal scenario/case. If there will be an unusual event happening in the scenario then it will be reflected in the trace file. So the trace analysis script may fail with segmentation fault or divide by zero error or type error.
So just try to change the awk script little bit to handle such unusual situation.

The following link is discussing about another possibility.
