If you have exactly the same software installed on both motes and the motes
dont rely on any "third factor" which hand out a seed for the "random"
number generator you will always get the same order of the "random" numbers
on both motes. The reason I highlight the word random is because random
number generators on computers are seldom random. They are often built on
some number generators that produce pseudo-random numbers which in turn rely
on a seed to produce different sequences of numbers.

My first question would be if you must use the same TOS_NODE_ID? Using
different ones with RandomC would give different seeds for the generator and
in the end different numbers.
