[Smac-users] Segment faultRe: smac energy

[Li Liu]

Hi All,

I replaced the following files: smac.h/cc, wireless-phy.h/cc,
energy-model.h/cc, cmu-trace.h/cc in ns-2 with those from the latest
snapshot of ns-2 and tried to test the new energy model for smac by
using the script file from the smac website, but I got a segment
fault(of course, I rebuilt the ns2). Did I miss something for the
testing? I would highly appreciate any help from you.

Best regards,
Li

BTW, The message shown on the screen:

num_nodes is set 2
warning: Please use -channel....

NOTE: SMAC is running with sleep-wakeup cycles.....

channel.cc:sendUp - Calc highestAntennaZ_ and distCST_
Segmentation fault (core dumped)
