Abstract

Recently, most mobile nodes, such as smartphones, will have multiple wireless radio interfaces. This feature allows a mobile node to access a multi-network through multiple wireless radio interfaces simultaneously. Accordingly, various networking technology has been studied to use wireless multi-interface more efficiently. In this paper, MPTCP based handover scheme is proposed to reduce data loss and end-to-end latency during the handover in PMIPv6 domain. The proposed scheme performs 2-step flow mobility on the multi-path established through the multi-interface of mobile node in the handover procedure and uses MPTCP subflow function to overcome end-to-end disconnection during the handover. Therefore, the proposed scheme takes the advantage of being able to minimize data loss and a latency generated during performing the handover of mobile node.

최근 무선기술의 발전으로 인해 스마트폰과 같은 이동노드는 멀티인터페이스를 장착하고 있다. 이와 같은 특징은 이동노드가 멀티네트워크에 동시 접속을 가능하게 하고 있다. 이에 따라 멀티인터페이스를 활용할 수 있는 다양한 네트워킹 연구가 진행되었다. 본 논문에서는 이와 관련해서 멀티인터페이스 이동노드가 PMIPv6 도메인에 접속한 환경에서 핸드오버 발생 시 데이터 손실을 줄일 수 있는 MPTCP 기반의 핸드오버 기법을 제안한다. 제안하는 핸드오버 기법은 특정 네트워크 인터페이스의 핸드오버 수행 시 멀티인터페이스를 통해 2 단계 플로우 이동성을 수행하고 MPTCP 서브플로우 기능을 통해 단대단 끊김 현상을 극복한다. 따라서 제안하는 기법으로 이동노드의 핸드오버 시 발생하는 데이터 손실을 줄이고 핸드오버 지연을 최소화 할 수 있는 장점을 가지고 있다.
