A ubiquitous sensor network system, and a method distinguishing between friend and foe by using the same are provided to prevent the consumption of unnecessary energy of sensor nodes by making nodes having mobility not communicate with the sensor nodes placed at a sensor field. A specific mobile node(120) informs other mobile nodes, which are connected to each other through a network, of the communication connection with the specific sensor node. When the other mobile nodes, which are informed of the communication connection, enter the sensor field, the other mobile nodes do not respond to the query of sensor nodes within the sensor field. The specific mobile node provides a sensor node(110) with their ID information and the ID information of the mobile nodes connected the mobile node through a network.
