Fast Data Access through Nearest Location-Based Replica Placement

Algorithm 1

Nearest location-based replica selection and placement algorithm.

(1)	Initialize population with data centers of Index table
(2)	Initialize user base
(3)	Initialize broker
(4)	Initialize index table
(5)	Initialize population of all data centers
(6)	Initialize index
(7)	Initialize data center controller
(8)	Initialize Internet characteristics with latency order by region
(9)	Initialize broker with Internet characteristic values
(10)	Save the best solution with its fitness
(11)	while best data center is not found do
(12)	SELECT parents
(13)	RECOMBINE pairs of regions
(14)	MUTATE the resulting regions
(15)	EVALUATE data centers based on latencies
(16)	SELECT individuals for the new generation
	end
(17)	Function select lowest latency data center
(18)	Initialize characteristic lists in lowest latency first calculated from regions
(19)	if datacenter has a fitness value better than other data centers then
(20)	select best first data center located at first top two positions in the proximity list
(21)	else if more than two data centers are located with similar latencies then
	then
	select two centers randomly and place data at both of them.
