[Retracted] A Novel Variable Pseudonym Scheme for Preserving Privacy User Location in 5G Networks

Algorithm 1

VI-Pool initialization algorithm.

	Input: limits of range length MAX and MIN
(1)	Set Avail = 2^16
(2)	Set Stop = 0
(3)	Set S = 0
(4)	While Avail ≥ min do
(5)	Generate a random M between MAX and MIN (MIN ≤ M ≤ MAX)
(6)	If Avail < MIN then
(7)	M = Avail
(8)	End if
(9)	S = Stop;
(10)	Stop = Stop + (2/3) M
(11)	Generate a new record at VI-pool
(12)	Insert a tuple (S, M) into new record at
(13)	VI-pool
(14)	Avail = Avail–M
(15)	end while
