Disclosed is an expression method of sensor node data in a ubiquitous sensor network. According to one aspect of the present invention, in the expression method of sensor node data in a ubiquitous sensor network, the sensor node data is expressed as an XML document to enable mechanical data processing, and a schema structure of the XML document includes a description element for describing data about a sensor service and an observation element for describing data about a sensor and observed data, as highest-level elements. The description element has a cardinality of minimum 0 or maximum 1. The observation element has a cardinality of minimum 1 or maximum 1. |
