Embodiment Construction
[0046] The present invention provides a pseudo-random sequence generation method for wireless sensor network nodes. The pseudo-random number sequence generation method reintroduces the output random sequence value into the calculation process of the next random sequence value, so that the generated new While maintaining its original random characteristics, the D-sequence of D-sequence changes the original (1 / p) R The limited cycle period of D-sequence expands its sequence length. The working principle of this pseudo-random sequence generation method for wireless sensor network nodes can be expressed by formulas (1) and (2):
[0047] S(i)=floor(x(i-1) / p) (1)
[0048] x(i)=R×mod(x(i-1),p)+S(i) (2)
[0049] Among them, R is the base number, the denominator p is a prime number, the floor operation is a rounding operation, the Mod operation is a remainder operation, x(0) is set to R, and the random sequence generator can generate a corresponding random sequence S(i ), S(i) is an ...
