Cyclic sleep management schemes of backup transponders for power saving and high-speed failure recovery

We propose cyclic sleep management schemes for backup transponders to achieve simultaneously low power consumption and high-speed failure recovery time. Recovery time shorter than 50 ms was obtained with 38 % power saving on backup transponders.
