Apparatus and method for generating virtual sensor in sensor network

An apparatus for generating a virtual sensor in a sensor network comprises steps of: setting a communication connection to a sensor node located near a smart device; generating logical sensors corresponding to physical sensors connected to the sensor node and generating virtual sensors by using the logical sensors; and providing an application service for a user by using the virtual sensors.
