[ns] R: Underwater acoustic channel model?
Christian, ns-2 does not support any of the models/protocols you mentioned. I think you will have to code and add to the simulator them if you want to use them within ns.

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
Re: [ns] regarding patch for ns 2.28
Hi, You can always try to compile ns-2.28 on an FC5 and see what kind of errors you can get. I did the same for the bare ns-2.29.2 on FC5. I only got some really easy to fix errors like removing class names prefixes on class member variables declaration (this should affect a couple of .h files) and some forward declared functions that should be moved to the beginning of the .cc module to get the compiler to reference them. For the 4.0.2 patch, you can just try it out on a fresh install of ns-2.28 on FC5. If it works then that would be fine. If it's not the case, you can always edit the patch file to see where it went wrong and try to apply the difference manually by editing the affected source file. There is always a solution.

Anyways thanks so much. Himanshu Hi! There is already ns-2.29.2 on sf.net. Why are you trying to install ns-2.28? I don't think that the patch for GCC 4.0.2 will work on the 2.28. Generally speaking, a patch is very tied to the original source code it was built from. To get ns-2.29.2 installed on FC5 you'll have to apply the patch provided by Tom Henderson and Qihe Wang. Check this link http://mailman.isi.edu/pipermail/ns-users/2006-May/055811.html . Hope it helps, Ilyes Gouta. hdwivedi wrote: Hi ilyes, I have a simple query. I am trying to install ns 2.28 allinone on fedora5 which has gcc 4.1 in it.Could please let me know if the patch for ns 2.28 gcc 4.0.2 would work for gcc 4.1 as well. i will very much appreciate if you can find time to answer this question. regards, Himanshu dwivedi
