Duty-cycling schemes allow devices to dynamically adjust their active period to conserve energy. On the other hand, synchronization schemes allow multiple coordinators to schedule their transmissions in order to prevent the overlapping of superframe schedules. In this paper, we analyze the impact of a synchronization mechanism on duty-cycling schemes in an IEEE 802.15.4 cluster tree network. We show the necessity of an operational synchronization mechanism when devices adopt an independent duty-cycling approach so that the later accounts to effective energy savings.
