Abstract
The present invention relates to a method for cluster based data in wireless sensor networks. The method includes: selecting any one of border nodes positioned at the edge of a cluster as a temporary cluster head as a temporary cluster head when a target is sensed in the cluster; bugging data of the temporary cluster head by border nodes in other adjacent cluster which do not sense the target to temporarily change the border node selected as the temporary cluster head to a cluster head of each of the border nodes; when the target is sensed by at least one of the border nodes, collecting data from each of the border nodes by the temporary cluster head to transferring the collected data to an actual cluster head of the temporary cluster head; and aggregating the collected data by actual cluster head of the temporary cluster head.
