[Ns-developers] Underwater acoustic module for NS-3

[Leonard Tracy]

Hi Everybody (again),

I've done some more work on the NS3 Underwater Acoustic Networking model I'd
like to submit for design review.  My basic goal has been to develop a model
suitable for the simulation of Layer 2 and Layer 3 protocols in underwater
networks.  As modeling of the underwater acoustic channel is complex, I've
attempted to provide support for variety of propagation models as well as a
PHY model that can be tailored to represent a variety of modulations.  I'd
appreciate input on the design and implementation.  The repository has been
moved to:  http://code.nsnam.org/ltracy/ns-3-dev-uan

A couple of known open issues:  1. I plan on reworking UanPropModelBh
(possibly to store information in a SQL DB).  2.  I'm guessing that
UanTxMode can likely be combined with WifiMode.
