An apparatus and method for controlling the execution of mashup WoT service are disclosed herein. The apparatus includes a WoT mashup service functionality entity, a WoT service execution functional entity, and a WoT service repository. The WoT mashup service functionality entity makes a response to a mashup WoT service request from a WoT service user by executing a mashup WoT service optimized for the WoT service user. The WoT service execution functional entity returns the results of simple WoT services to the WoT mashup service functionality entity in response to a request for the execution of the simple WoT services for the execution of the mashup WoT service from the WoT mashup service functionality entity. The WoT service repository stores WoT service execution descriptions each descriptive of execution logic for each of the simple WoT services.

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.
