- W2003074896 abstract "본 논문에서는 센서 네트워크에서 효율적인 조인 처리를 수행하여 통신비용을 최소화할 수있는인-네트워크 조인 전략인 RFB(Record Filtering using Bit-vector) 조인 전략을 제안하였다. 제안하는 조인 전략은 통신비용을 감소하기 위하여 데이터의 크기를 줄이기 위해 비트 벡터(Bit-vector)를 이용한다. 또한, 센서 네트워크의 특성상 조인을 위해 중앙의 서버로 모든 데이터를 전송하기가 어렵기 때문에 본 논문의 조인 전략은 조인 처리의 이른 단계에서 조인 결과에 해당되지 않는 데이터를 제거하여 불필요한 통신비용을 감소시켜 통신비용을 최소화하기 위한 네트워크 내에서 효율적인 조인 질의 수행 전략이다. 본 논문에서는 시뮬레이션을 통하여 기존의 대표적인 조인 전략인 시놉시스를 전송하여 조인을 수행하는 시놉시스 조인(Synopsis Join, SNJ)과 비교하여 통신비용 효율적임을 보였다. The paper proposes RFB(Record Filtering using Bit-vector) join algorithm, an in-network strategy that uses bit-vector to drastically reduce the size of data and hence the communication cost. In addition, by eliminating data not involved in join result prior to actual join, communication cost can be minimized since not all data need to be moved to the join nodes. The simulation result shows that the proposed RFB algorithm significantly reduces the number of bytes to be moved to join nodes compared to the popular synopsis join(SNJ) algorithm." @default.
