SENSOR NODE IDENTIFICATION METHOD FOR HIERARCHICAL SENSOR NETWORK AND COMPONENT THEREFOR

摘要

PURPOSE: A sensor node identification method in a hierarchical sensor network and a component thereof are provided to provide a world class identification system by variably composing the identification information for identifying a target sensor node intrinsically according to each layer of the sensing service network. CONSTITUTION: The sensing request including the sensor node identification information is received from a second component of a second layer(S101). An identifier of the first layer of the sensor node identification information accords the identifier of the first component, the identifier of the first component is removed in the sensor node identification information(S102-2). The sensor node identification information is corrected. The sensing request including the corrected sensor node identification information is transmitted to a third component of a third layer(S103).
