摘　　要：针对无线传感器网络在节点传输过程中的延迟与链路质量问题,设计一种基于能量探测的节点休眠调度算法EAS,通过对节点插入苏醒时隙来减小端到端之间的延迟,并根据每个节点的剩余能量值进行能量探测,使整个网络中各节点的能量相对均衡地消耗,在保证传输质量的基础上达到延长网络的生命周期的目的。实验结果表明,对比现有算法,EAS算法能够在保证使WSN网络在延迟一定的情况下明显降低能耗,延长整个网络的工作寿命。During the process of node transmission,an energy-aware based scheduling scheme（EAS）can be designed against the delay and link quality problem in WSN. Through inserting time slot into the node,the port-to-port delay can be reduced;in the meanwhile,the remaining energy value of each node can be detected,thereby relatively con-suming the energy of each node in the network on a balanced basis,and extending the network lifecycle on the prem-ise of ensuring the transmission quality. Test finding shows that EAS scheme can significantly reduce energy con-sumption by stabilizing WSN delay,thus extending the working life of entire network.
