초록

무선 센서 네트워크에서의 결함 허용은 센서 노드의 취약성 보완과 신뢰성 높은 정보 제공을 위해 필요하다. 센서 노드들의 자원 제약적인 특성 때문에 오류에 노출되기 쉬우며, 기존의 체크포인팅 기법 들은 센서 네트워크의 특성을 고려하지 않고 설계되었기 때문에 이를 적용하기 어렵다. 본 논문에서는 클러스터 기반의 라우팅 프로토콜에 체크포인팅 기법을 적용하여 헤드 노드의 결함 시 발생할 수 있는 정보 손실과 높은 복구 비용 문제를 해결하는 방법을 제안한다.

In wireless sensor networks, a fault-tolerant scheme that detects the failure of sensor nodes and improves the reliability of collected information must be considered. Resource-constraint sensor nodes expose vulnerability and cannot use existing checkpointing schemes that do not consider a feature of sensor networks. In this paper, we propose a fault-tolerant scheme for clustering routing protocols that support the recovery of a head node.
