Abstract:

Energy constraint is a crucial factor limiting the performance of single-lamp monitoring WSN (wireless sensor network)for airfield navigation lights. To reduce energy consumption of nodes and thus prolong lifetime of WSN,nodes are designed from three aspects appr including hardware energy consumption, software controlling structure 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.
