Then go through the generated trace file and lock for lines where packets are dropped because of a collision. This should look like:
d ............. COL .................... To get the packet loss rate you should count send and received packets on the MAC or AGT layer that are not broadcast. The lines look like: s .......... MAC ................... r .......... MAC ................... or s .......... AGT ................... r .......... AGT ................... For broadcast packets (destination -1) you first need to define what a lost packet is. You will find the exact format in the ns2 documentation (trace file format) Daniel.
