The randomized number algorithm can be used to model physical structure node deploy WSNs is a probability distribution by random number using Monte Carlo methods, this is the one. Extending this model is randomized number generator are usually produced a number in the range [0, 1] is coming out by chance that the randomized distribution that are coming out, there will be one of the values in the range will have the same value. Therefore, in order to bring random numbers to apply to various two parameters of structure WSNs are total number of node and hop distance (h) must convert the number to a random number in the range of WSNs
