摘　　要：机场助航单灯监测无线传感器网络节点存在能量约束问题。为降低节点能耗、延长网络寿命,从硬件能耗、软件控制、路由算法3个方面讨论了节点的节能设计。寿命评估可为传感器网络的可靠性设计及节点维护提供依据。通过差分采样能耗测试方法测试了节点能耗,为系统整体寿命评估提供了初步依据。Energy constraint is a crucial factor limiting the performance of single-lamp monitoring WSN （wireless sensor network） for airfield na^i~gafion lights. To reduce energy consumption of nodes and thus prolong lifetime of WSN, nodes are designed from ithree aspects appr including hardware energy consumption, software controlling struc- ture and routing algorithm. Lifetime appraisal of nodes facilitates reliability design of WSN and maintenance of nodes. By accomplishment of differential-sample-based node energy consumption measurement, the appraisal of lifetime is fundamentally made valid.
