User Association and Small-Cell Base Station On/Off Strategies for Energy Efficiency of Ultradense Networks

Algorithm 4

SBSs on/off strategy algorithm.
(1)Initialization:
(2)All BSs hold “on”, i.e., ; ;
(3)Sort ;
(4)repeat
(5)Turn off FBSs i base on the load of FBSs;
(6)Update the EE by the user association algorithm, set , and record the number of FBSs turned off is n;
(7)until
(8)Calculate the time of each FBS;
(9)Sort in declining order;
(10)repeat
(11)Turn off FBSs m base on ;
(12)Update the EE by user association algorithm, set ;
(13)until
