Zusammenfassung: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. 본 발명의 실시예에 따른 센서 노드를 그룹화하는 방법은 다중 싱크 노드 환경에서 센서 노드에 의해 수행되는 그룹화 방법으로서, 주변 노드들에 헬로 패킷(hello packet)을 전송하는 단계, 상기 주변 노드들로부터 응답 패킷(reply packet)을 수신하는 단계, 상기 응답 패킷(reply packet)에 포함된 싱크넘버(sink number)와 그룹넘버(group nember)를 추출하는 단계, 각각의 싱크노드를 기준으로 상기 주변 노드의 그룹넘버들을 계산하는 단계 및 상기 주변 노드의 그룹넘버들에 싱크 임계값(K)을 더한 값들과 상기 센서 노드의 기존 싱크 노드에 속하는 그룹넘버를 비교하여 최소값을 선택하는 단계를 포함한다.
