Abstract: PURPOSE: A sensor node operation method is provided to prevent routing information from being propagated to an entire sensor field. CONSTITUTION: A plurality of clusters are formed by grouping neighborly-located sensor nodes(S100). A sensor node, which is the nearest to the center region of a cluster and has remaining energy, is selected as the head node of each cluster(S200). When the head node is successfully selected, all data packets are forwarded through the head node(S300). When a head node reselection period comes around after predetermined time, a new head node is selected after updating the location information of each sensor node to the most up-to-date information(S400).
