Summary: | The present invention includes a base station and a plurality of nodes. Each node included in the plurality of nodes calculates a rank through message exchange with a neighbor node located within a predetermined transmission distance for each time slot according to a duty transfer protocol, sets its role based on the calculated rank, and determines whether to include a broadcast backbone based on its role when receiving a merge message corresponding to the base station. At this time, the role includes a dominator and a dominate, The dominator is a node which sends a message to a neighboring node in a specific time slot The dominate is a node which receives a message from the dominator in a specific time slot. The broadcast backbone is a network composed of a plurality of nodes which receive a message transmitted from the base station.
본 발명은 베이스 스테이션 및 복수의 노드를 포함하고, 복수의 노드에 포함된 각 노드는 듀티-전송 규약에 따라, 타임 슬롯 별로 미리 정해진 전송 거리 내에 위치한 이웃 노드와 메시지 교환을 통하여 랭크를 산출하고, 산출된 랭크에 기초하여 자신의 역할을 설정하고, 베이스 스테이션에 대응하는 병합 메시지를 수신하면, 자신의 역할에 기초하여, 브로드캐스트 백본의 포함여부를 결정한다. 이때, 역할은 전파자 및 피전파자를 포함하고, 전파자는 특정 타임 슬롯에 메시지를 이웃 노드로 전송하는 노드이며, 피전파자는 특정 타임 슬롯에 전파자로부터 메시지를 수신하는 노드이고, 브로드캐스트 백본은 베이스 스테이션으로부터 송신된 메시지를 전달받은 복수의 노드로 구성된 네트워크이다. |
