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

Algorithm 2

Privacy-aware cloudlet identification.

Input: The selected running cloudlets

   The known shortest time vertex set

   The unknown shortest time vertex set

   The collections and

   The VM occupation record

Output: The cloudlet with the shortest time

Get the transmission time between each cloudlet in from to

Add the source cloudlet () to p and set its dis = 0

if is directly connected to the source cloudlet then

end if

sort in the increasing order of the transmission time

  for each cloudlet in   do

   if   +   then

 end if

  end for

sort    in the increasing order of the transmission time
