I would assume that rand16() returns a 16 bit random number so you will have to do some calculating to range it to 0->1. But I recommend avoiding floating point on the controller side whenever possible because there is no hardware support for it.
I don't know why you get the same number on each call as I would expect the float cast to just give you the int16 values themselves. Maybe try making your "random" variable an int and see what... Also look at the Random interface, there should be some kind of seed() call which would allow starting the pseudo sequence from a different point on each of your motes. The easiest would be to use the moteID as the seed on each device.
