SENSOR NODE AND RELIABLE METHOD FOR TRACKING BOUNDARY OF CONTINUOUS OBJECTS USING ASSISTANCE NODE IN WIRELESS SENSOR NETWORK

摘要

A method for tracking a boundary of continuous objects, capable of ensuring reliability by additionally selecting an assistance node, the method including a boundary information reception operation dividing sensor nodes, according to a plurality of predetermined areas to select representative nodes each representing sensor nodes, and receiving boundary information including event sensing information from the representative nodes that collect the boundary information from the sensor nodes, a representative node information reception operation selecting one or more assistance nodes configured to collect representative node information from the selected representative nodes, and receiving the representative node information from the assistance nodes that receive the representative node information, as well as a continuous object boundary implementing operation implementing a boundary of continuous objects by combining the boundary information or the representative node information that is received from the respective representative nodes and the respective assistance nodes.

1. A method for tracking a boundary of continuous objects, the method comprising:
selecting representative nodes each representing sensor nodes in a plurality of predetermined areas into which one or more sensor nodes that sense a continuous object event are divided, and receiving boundary information including event sensing information from the representative nodes that collect the boundary information from the sensor nodes in the respective predetermined areas; selecting one or more assistance nodes configured to collect representative node information from the selected representative nodes, and receiving the representative node information from the assistance nodes that collect the representative node information from the representative nodes; and implementing a boundary of continuous objects by combining the boundary information or the representative node information that is received from the respective representative nodes and the respective assistance nodes.
