摘　　要：为减小低占空比无线传感器网络(LDC-WSN)中端到端的休眠延迟和均衡能量负载,提出了一种动态能量感知的节点休眠调度算法(DESS),该算法通过感知节点剩余能量的动态变化,自适应地增加苏醒时隙的次数,用以平衡网络中节点的能量消耗。仿真结果表明,与同类算法的LES和TOSS相比,DESS在休眠延迟以及能源消耗等方面带来明显的性能提升,有效地延长网络的生命周期。In order to reduce the end-to-end delay in a Low-Duty-Cycle Wireless Sensor Network(LDC-WSN)and balancethe energy load of the network,a Dynamic Energy-aware Sleep Scheduling algorithm(DESS)is proposed.This algorithmadaptively increases the number of times of active time-slot to balance energy consumption of the nodes by perceivingdynamic residual energy of them.The simulation shows that,compared with the LES and TOSS,DESS can achievesignificant performance improvement in terms of energy-saving and end-to-end delay in the situation of the same requirementdelay and therefore prolong the network lifetime.
