Edge Server Placement for Service Offloading in Internet of Things

Algorithm 3

Edge server layout strategy based on PSO.

	Inputs: K chromosomes that have been iteratively optimized by GA, Number of iterations T, Variable t
	Output: K chromosomes optimized by PSO
(1)	for t = 0 to T do
(2)	if t == 0 then
(3)	Initialize the velocity of each particle of K chromosomes
(4)	else
(5)	Adjust the position of each particle according to formulas (23) and (24)
(6)	end if
(7)	end for
(8)	return K chromosomes
