According to the present invention, when a movement occurs in a clustering-based mobile sensor node, a wireless network using a cluster structure supporting mobility of a mobile sensor node that allows access to a new cluster based on a beacon signal after detecting the mobility of the corresponding mobile sensor node is detected. The present invention relates to a sensor network system and a wireless sensor networking method using the same, wherein a wireless sensor network system using a clustering structure supporting mobility of a mobile sensor node according to the present invention includes a mobile sensor included in a cluster of a wireless sensor network. node, and having at least one of the cluster head node and included in the cluster belonging cluster head node of the cluster head node is a transmission period of a beacon (beacon) message T beacon is set for the other mobile sensor nodes of the cluster, Emitter and the mobile sensor nodes to transmit, the signal strength received from the beacon message, the cluster head calculated the R th value of signal strength to support the transfer of data at the same time to retain the function of calculating the signal strength of a node is set to the cluster head node And a plurality of cluster member nodes for calculating a distance to the cluster head node through the R th value, and a base station for receiving data of the cluster member node collected and transmitted from the cluster head node.
