ABSTRACT = {In Wireless Sensor Network (WSN), because battery and energy supply are
constraints, sleep scheduling is always needed to save energy while maintaining
connectivity for packet delivery. Traditional schemes have to ensure high duty cycling to
ensure enough percentage of active nodes and then derogate the energy efficiency. This 
paper proposes an RFID based non-preemptive random sleep scheduling scheme with 
stable low duty cycle. It employs delay tolerant network routing protocol to tackle the 
frequent disconnections. A low-power RFID based non-preemptive wakeup signal is used 
to confirm the availability of next-hop before sending packet. It eliminates energy 
consumption of repeated retransmission of the delayed packets. Moreover, the received 
wakeup signal is postponed to take effect until the sleep period is finished, and the waken 
node then responds to the sending node to start the packet delivery. The scheme can keep 
stable duty cycle and then ensure energy saving effect compared with other sleeping 
scheduling methods.},
