Created attachment 1322

wimax-simple.cc with added duration and mobility

In a simple experiment based upon the wimax-simple.cc script I added mobility
to the subscriber station so that at a certain time it moves out of range, and
at a later point within range.  The simulation halts with the an assertion
failure around the point in time when I guess the subscriber is out of range.
The assertion failure is this:

assert failed. cond="!m_ss->IsRegistered ()", msg="Subscriber Station: Error
while scanning: Already registered with a BS",
file=../src/wimax/model/ss-link-manager.cc, line=143
terminate called without an active exception

Command
['/Users/mglindeb/Documents/workspace/ns-3.13/build/scratch/wimax-simple']
terminated with signal SIGIOT. Run it under a debugger to get more information
(./waf --run <program> --command-template="gdb --args %s <args>").

I am attaching the simulation script..
