Post #4, @nivedita sai : Welcome to LQ.
'nrlsensorsim' :
nrlsensorsim-2.29.tar.gz / um-olsr_for_nrlsensorsim-2.29.patch
I did build the above '24 Apr 2013', post #4 here
http://www.linuxquestions.org/questi...-4175459230/#4
... But not very usable as none of the available files.tcl works.
Better go for the proof version : ns-allinone-2.26 .
How to build nrlsensorsim :
You will have to tell which Linux OS it's about :
1) $ uname -m
2) $ cat /etc/*release*
