RELIABLE TRACKING METHOD OF CONTINUOUS OBJECTS USING BOUNDARY ASSISTANCE NODE IN WIRELESS SENSOR NETWORKS AND SENSOR NODE THEREFOR

摘要

A method for tracking a reliable boundary line of continuous objectives is disclosed by additionally selecting an assistance node except for a reference node. The method for tracking a reliable boundary line of the continuous objectives comprises a boundary information reception step of selecting the reference node which represents sensor nodes within each predetermined area by dividing at least one sensor node into multiple predetermined areas and of receiving boundary information from the reference node which collects the boundary information including the existence of event sensing from the sensor nodes of each predetermined area; a reference node information reception step of selecting at least one assistance node to collect the reference node information from the selected reference nodes and of receiving the reference node information from the assistance node which collects the reference node information from the reference nodes; and a continuous objective boundary line realization step of realizing the boundary line of the continuous objectives by combining the reference node information or the boundary information received from each reference node and each assistance node.
