초록

모바일 환경에서 현재의 MIP 기반 핸드오버 기법은 여러 문제점을 가지고 있어 끊김 없는 서비스를 제공하는데 한계가 있는 것으로 알려져 있다. 최근 MIP기반 핸드오버 기법에서 좀 더 효과적인 QoS를 제공하기 위해 MRSVP, HMRSVP 등 여러 연구가 진행되었지만 MIP 기반 모바일 환경 자체가 가진 근본적인 여러 문제 때문에 QoS 관련 연구의 한계를 가질 수밖에 없다. 본 논문에서는 모바일 환경에서 이동 중 QoS를 제공하기 위해 이동성 SCTP 기반의 핸드오버 기법에서 종단 간 QoS 제공기법인 IntServ를 도입하는 메커니즘과 효율적인 경로관리를 고려한 QoS 제공 방안을 제안하고자 한다. 제안된 기법은 모바일 노드의 이동으로 빈번히 일어나는 핸드오버 시마다 종 단간 예약을 다시 해야 하는 예약비용을 줄이기 위해 중복되는 경로 지점을 찾아 새로운 부분만 다시 예약하는 기법에 대한 것이다. 또한 SCTP 기반의 RSVP와 MIP 기반의 RSVP에 대한 문제 분석과 해결방안을 제안하고 예약비용 분석을 통해 비용 절감효과의 타당성을 평가검증 한다.

It has known that the handover based on MIP in mobile environments has many constraints for proving seamless service due to well hon problems. Although there has been researching for the solutions, such as MRSVP and HMRSVP etc, it is difficult to do the research related with QoS due to the issues based on MIP used as a seamless mobility. In this paper, the seamless provides in a mobility based on SCTP, which is applied by IntServ for end-to-end QoS service. The paper also proposes the path management scheme for saving reservation cost. the scheme searches a new path on the moving mobile terminal and reserves the resources on the path for providing seamless QoS service. The paper is also analyzed on the comparition between a SCTP based and MIP based solutions. the scheme is evaluated using the cost effect saved for resource reservation.
