hi everyone,
i installed ns-2.1b8-mcast on RedHat7, it seems that i installed correctly (i
run one of the ns examples)
then i try to run ADMR protocol, i try the command from README
(http://www.monarch.cs.rice.edu/ftp/multicast/README)
./ns scripts/run.tcl -x 1200 -y 800 -nn 100 -stop 900 -tr TRACES/out.tr -mg
mcast_communication_scenarios/cbr_100_4x64_3x3x20_mcast_ns_rs -sc
movement_scenarios/scen-1200x800-100-0-20-1 -rp admr > & TRACES/sim_stdoutput
after 31 minutes it gives me segmentation fault, but when i look at TRACES
folder, there are two files, (sim_stdoutput, out.tr)
i don't know where is the problem, is it from admr.tcl file? i attache both
run.tcl and admr.tcl,
please help me, i really need it for my dessertation, but no result yet.
