[ns] Simulating infrastructured wireless networks in ns2

-protocol-free access points (i.e. using typical 802.11 connection). Any help and / or example code as to how this is done would be appreciated greatly. Sincerely, Theresa Nelson Virginia Tech

[ns] ERROR: Undefined symbol when making ns2 after code patch

[ns] Alternatives to "flatgrid"

a non-zero z coordinate, but then I got unexpected results and again looked through my code. I then realized that every simulation example I had seen has "$topo load_flatgrid $opt(x) $opt(y)". Is there a way to load a 3D grid, rather than a 2D grid? If so, how is that done? Thanks in ad

[ns] Floating Point Exception when using Shadowing radio propagation model

eeSpace or TwoRay I have no problem. Has anyone else had this issue? How do you fix it? I'm attaching some code; if more code is necessary to look at, please let me know and I'll add the whole file. Thanks in advance. Theresa Nelson - [EMAIL PROTECTED] M.S. Computer Engineering Networks &am
