Abstract: A clustering system where proxy is possible in a wireless sensor network, a method thereof, and a recording medium thereof are provided to equally consume energy without CH having low energy by using a proxy node, improve the overall performance of a sensor network system, and increase the lifetime of each sensor, thereby improving overall reliability of the sensor network system. In a clustering method where proxy is possible in a wireless sensor network, configuration of a round for transmitting data, collected in a sensor node, to a BS(Base Station) comprises the following steps. In a setting step, the sensor nodes are organized in a cluster type(ST2010,ST2020,ST2030,ST2040). In a maintenance step, data collected by each sensor node is transmitted to the BS(ST2050). A node having the shortest transmission distance and the most redundant energy among member nodes of the cluster is selected as a proxy node and has authority of CH(Cluster Head) to fairly disperse energy consumption of the sensor nodes.
