초록

클라우드 컴퓨팅 환경에서 Infrastructure as a Services (IaaS), Platform as a Services (PaaS), Software as a Services (SaaS), Desktop as a Services (DaaS) 등 다양한 솔루션들이 지속적으로 제공되고 있다. 현재는 사용자 단말이 클라우드 서비스를 제공받으면서 이동성을 보장하기 위한 솔루션으로 Mobile as a Services(MaaS)가 가장 많은 주목을 받고 있다. 사용자는 이동을 하면서도 클라우드에 있는 데이터 및 어플리케이션에 대한 접근과 이용이 가능해야 한다. 다시 말해 모바일 Thin-Client 환경에서 클라우드와 통신, 이동성 지원은 필수 요소이다. 모바일 단말의 이동성을 지원하기 위해 MobileIPv6 (MIPv6) 및 Proxy Mobile IPv6 (PMIPv6)가 소개되면서 많은 연구가 진행되고 있다. 또한, PMIPv6에 대한 연구는 도메인 내에 패킷 손실을 우려한 최적 경로 설정, 빠른 핸드 오버 등의 개선방안이 많이 제시된 바 있다. 본 논문은 모바일 Thin-Client 지원을 위해 PMIPv6 및 클라우드 연동 시스템을 제안한다. 제안한 시스템에서 모바일 Thin-Client가 서비스를 지원받기 위해 Replica서버를 이용하여 원활한 서비스를 제공하는 기법을 제안하며 성능평가를 통하여 기존 PMIPv6에서 핸드오버에 대한 데이터 비용을 비교 분석할 것이다.

In a cloud computing environment, various solutions were introduced to provide the service to users such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS) and Desktop as a Service (DaaS). Nowadays, Mobile as a Service (MaaS) to provide the mobility in a cloud environment. In other words, users must have access to data and applications even when they are moving. Thus, to support the mobility to a mobile Thin-Client is the key factor. Related works to support the mobility for mobile devices were Mobile IPv6 and Proxy Mobile IPv6 which showed performance drawbacks such as packet loss during hand-over which could be very critical when collaborating with cloud computing environment. The proposed model in this paper deploys middleware and replica servers to support the data transmission among cloud and PMIPv6 domain. It supports efficient mobility during high-speed movement as well as high-density of mobile nodes in local mobility anchor. In this paper, through performance evaluation, the proposed scheme shows the cost comparison between previous PMIPv6 and verifies its significant efficiency.
