Hi,

Where i can obtain source code (preferably MATLAB or C) for modeling an ad hoc or wireless mesh network?

I'd want to monitor the performance of a wireless mesh network under different methods of beamforming. Hence, it'll be helpful to have a basic wireless mesh network model for me to improvise on.

I've googled extensively in search of a basic source code for a ad hoc or wireless mesh, which can help me get started, but failed.

Any help would be greatly appreciated.
 

Hi I need some suggestion I am doing a project on RF-ID industry disaster basically the programing has on micro-controller but i want to run this project in MATLAB it possible.

hi freind's . i write this code's and run in nam(((---->cygwin in window 7 ))) ( code is copy here :C:\cygwin-ori\usr\local\ns-allinone-2.29\ns-2.29\aodv))
code's download from here :

and code hsoft_project.tcl fronm this forum

but all of code's display one error :((why and how solution :)))
$ ns wireless4_1node.tcl
invalid command name "i>>?set"
while executing
"i>>?set val(prop) propagation/TwoRayGround "
(file "wireless4_1node.tcl" line1)

please help me for solution error .!!!!!!
thx
