Hi guys, I'm very new to ns, and I'm trying to figure out whether or not I'll need to develop some new models for what I need to do. If found no documentation on what I'm looking for. Can anyone tell me if ns has support for any of the following?
- Underwater acoustic channels in which the noise level isn't uniformly dispersed? (I.e., where there are point-sources of acoustic noise that interfere with communication.) - Underwater acoustic channels where certain propagation paths simply don't exist? (The varied sound speed of water in a given environment can lead to some really wacky propagation paths.) - Directionally-transmitting modems. (The beam pattern can be somewhat complex, because the directionality can be accomplished using a multi-transducer array. This leads to a main lobe of sound in the intended direction, and some weaker lobes of sound in directions adjacent to the intended direction of transmission.) - MAC protocols for any commercially available underwater acoustic modems (such as WHOI MicroModems). I'm very grateful for any suggestions. Thanks, Christian
