Abstract: The present invention relates to a wireless sensor network system using a cluster structure and a wireless networking method using the same, wherein the cluster structure supports the mobility of a mobile sensor node by detecting the mobility of a mobile sensor node and allowing the mobile sensor node to access a new cluster based on a beacon signal when a cluster-based mobile sensor node moves. The wireless sensor network system using a cluster structure supporting the mobility of a mobile sensor node according to the present invention comprises at least one cluster head node, multiple cluster member nodes, and a base station. The at least one cluster head node is a mobile sensor node included in a cluster in a wireless sensor network, and a transmission cycle, T_beacon, of a beacon message for another mobile sensor node in the cluster is set in the cluster head node. The multiple cluster member nodes: are mobile sensor nodes transmitting data to a head node to which each cluster member node belongs among the cluster head nodes included in the cluster; have a function of calculating, from the beacon message, the signal strength of the cluster head node, and at the same time, a R_th value which is the signal strength to support data transmission is set; and calculate a distance from the cluster head node using the calculated signal strength of a cluster head node and the R_th value. The base station receives data on the cluster member nodes which are collected and transmitted by the cluster head node.
