Abstract

There are many problems caused by data sharing between general heterogeneous digital devices due to various interfaces. To solve this problem, this paper proposes heterogeneous data sharing with cloud service and mobile through D2D communication that supports communication between different devices. The proposed technique is used to reduce the load on the server to perform data synchronization. Also, in order to minimize data latency caused by data replication between different devices, a technique to enhance the speed of data writing with copying only the modified parts in the chunk list is adopted and cloud service model integrated with mobile environment is realized in order to minimize the network bandwidth consumed for synchronization for data sharing. Therefore, it is possible to share data in different spaces efficiently with maintaining data integrity and minimizing latency in data.

일반적인 이기종 디지털 장치들간의 데이터 공유는 다양한 인터페이스로 인해 많은 문제를 야기시킨다. 이런 문제를 해결하기 위해서 본 논문은 서로 다른 장치들간의 통신을 지원하는 D2D 통신을 사용하여 클라우드 서비스와 모바일을 결합한 이기종간의 데이터 공유를 제안한다. 제안된 기법은 데이터 동기화를 수행하기 위해 서버에 집중되는 부하를 줄이는 프로세스로 수행되며, 장치들간의 데이터 복제로 인한 지연을 최소화하기 위해 청크 리스트에 수정된 부분만을 복사하여 데이터 쓰기 속도에 기여하기 위한 기술을 채택하고, 데이터 공유를 위한 동기화로 소모되는 네트워크 대역폭을 최소화하기 위해서 모바일 환경과 결합한 클라우드 서비스 모델을 구현한다. 따라서 서로 다른 공간의 데이터를 효율적으로 공유하고 데이터의 무결성과 지연을 최소화할 수 있다.
