Energy-Efficient Cloudlet Management for Privacy Preservation in Wireless Metropolitan Area Networks

Algorithm 5

Global VM scheduling.

Input: The VMs

   Migration time

   Total operation time

Output: The cloudlets scheduling policy

Get the migration time ;

  Get the number of idle VMs on each cloudlets

  while   do

 Get from Algorithm 4

   if < utilization threshold level then

  Update the migration time as the next finish time of the VMs.

  Get migration compositions by Algorithm 3

  Schedule the VMs by the policy

  Set the vacant cloudlets to the sleeping mode

 end if

  end while
