Problem with simulation of AODV and DSR

Dear Sir,
I’m doing a project on performance comparison of AODV, DSR and DSDV protocols. I need awk which I can use to evaluate throughput, jitter and average delays ,and confidence interval from the simulations result traces.
but, i have segmentation fault, when i use awk file with DSR
in file dsr .tr , i obtain

SSendFailure 599.762584453 _25_ 442249 2 8:1 9:1 25->3 1 5 3 6 [10 |25 3 2 18 9 ]
