METHOD FOR GROUPING SENSOR NODE IN MULTI SINK NODE ENVIRONMENT

摘要

According to an embodiment of the present invention, a sensor node grouping method is a grouping method performed by a sensor node in a multi-sink node environment, and comprises the steps of: transmitting a hello packet to neighboring nodes; receiving a reply packet from the neighboring nodes; extracting a sink number and a group number included in the reply packet; calculating group numbers of the neighboring nodes based on each sink node; and selecting a minimum value by comparing group numbers belonging to an existing sink node of the sensor node with values obtained by adding a sink threshold value (K) to the group numbers of the neighboring node.
