Abstract

In a recent mobile computing environment, the research for a transaction model have been actively carried out to deal with real-time transaction. However, the research for recovery model is relatively insufficient. Therefore, it would be very important for mobile recovery methods for database stability, just in case of data loss due to hand-off in mobile computing system. So, further efficient research should be keenly done to reduce I/O hand-off in mobile computing systems. SLL method increases I/O time due to sequential file. This paper have been suggested to efficient mobile recovery method in mobile computing system. Finally, it has been clearly demonstrated for system efficiency, conducting the performance assessment that currently proposed recovery system.

최근 모바일 컴퓨팅 환경에서 실시간 트랜잭션 처리에 대한 트랜잭션 모델에 대한 연구가 활발히 진행되고 있다. 그러나 회복모델에 대한 연구는 상대적으로 미흡하다. 이러한 모바일 컴퓨팅 환경에서는 핸드오프가 발생하였을 경우 데이터 손실이 발생하므로 데이터베이스의 안정성을 위한 모바일 회복기법은 매우 중요하다. 그래서 모바일 컴퓨팅 환경에서는 입출력을 줄일 수 있는 효율적인 회복기법에 대한 연구가 절실히 요구된다. SLL기법은 순차파일로 구성되어 있기 때문에 입출력시간이 증가된다. 본 연구에서는 모바일 컴퓨팅 환경에서 효율적인 모바일 회복 기법을 제안하였다. 마지막으로 제한한 회복기법의 성능평가를 수행하여 효율성을 입증하였다.
