Edge Server Placement for Service Offloading in Internet of Things

Algorithm 1

Task transmission path confirmation algorithm.

	Inputs: Sensor S, Edge server ES, Task threshold of ES
	Output: Determined task transmission path
(1)	for n = 1 to N do
(2)	Find the nearest edge server esm
(3)	if the number of task of edge server esm  task threshold of ES then
(4)	Delete esm from ES
(5)	Go to step 2
(6)	else
(7)	Confirm that the sensor sn will transmit the task to the edge server esm
(8)	Number of tasks of edge server esm + 1
(9)	end if
(10)	end for
(11)	return Determined task transmission path
