mtrand.cc

it is used to generate random number to simulate the conmmunication scheme, very useful

/* This is a C++-ified version of the Mersenne Twister pseudo-random number
   generator based on a recode by Shawn Cokus. I didn't touch the original 
   code, the only changes I made were related to the task of wrapping it into
   a C++ class (renaming of functions and variables, changing them to class
   members, etc.).
   Martin Hinsch ([e-mail]), April 4, 1999.
   
   5.6.99 - Changed macro names to begin with a '__MTRAND_'.
