stds-802-16: RE: Published: MAC Modeling and Simulation Tools: Recommendations

Forwarded message from Matthew Sherman regarding MAC simulation tools...

Roger / Brian,

Your option if you want to echo this to the 802.16 reflector.  Just a few
comments on MAC simulation.

I know that I'm looking into SDL for 802.11 simulations.  A couple of other
people are also looking at this approach and feel there is merit.  While SDL
is really a software development tool (in my mind) there appears to be an
ability to simulate MAC performance as well.  Both 802.11 and Bluetooth
(802.15) include SDL models for the their MAC's directly in the
specifications.  One of the neat things about this approach is that their
can be direct feed back between the specifications, the simulations, and I
think the actual design process (where relevant).  SDL is available from
Telelogic (www.telelogic.com).  They will generally make the editor
available for free for standards work, although the actual simulator is
quite expensive.  Still, I know of several people going this route.

I had recently discussed MAC simulations with Nada Golmie at NIST and got
the impression (perhaps falsely) that she more favored a tool such as Opnet
or custom coding in C for MAC simulations.  Also, note that while an 802.14
model may be available in NIST's ATM simulator, I have also seen Opnet code
for 802.14, and I think NIST coded DOCSIS 1.1 in Opnet.  I believe NIST
would make their DOCSIS model available for free.  While, Opnet is not free,
it is commonly available at most large companies.

If you are serious about ns, you might also want to check out the monarch
web site and see if there is anything useful for you there.

I was looking at it for 802.11, but making all the little pieces play
together looked a bit daunting to me.

Just some friendly thoughts and comments.
