Virtual sensor network system for convergence of heterogeneous sensors

A virtual sensor network system according to an embodiment of the present invention includes a virtual sensor node that stores sensor data which is collected from a vehicle-mounted sensor through time synchronization, and provides the stored sensor data through time synchronization; and a master node that performs control on the virtual sensor node, and performs an algorithm which is used in an intelligent vehicle by using the sensor data. The master node is supplied with the sensor data stored in the virtual sensor node through time synchronization as virtual sensor data, without actual sensor data input from the vehicle-mounted sensor, when the algorithm is performed. Accordingly, even time deflection of the actual sensor data of the sensor can be reproduced by the configuration of the virtual sensor network system to which a time synchronization algorithm is applied, and thus reliable verification becomes possible during an algorithm development process.
