Abstract

In this paper, we propose a paging scheme considering local environment and moving patterns of mobile hosts on HMIPv6. The proposed paging scheme can adaptively construct a paging domain according to handoff probability of mobile hosts and local environment, and process a paging based on handoff probability stage by stage. For analysis of the proposed paging scheme, we simulate our scheme in two different experiment environments: an open environment like a square and a restricted environment like downtown. In experiment results, the proposed scheme shows superior performance to that of compared scheme all over. Particularly, in case of high call request rate and a restricted environment, the proposed scheme shows better performance.

본 논문에서는 HMIPv6환경에서 모바일 호스트들의 지역적인 환경과 이동 패턴을 고려한 페이징 기법을 제안한다. 제안한 페이징 기법은 지역적인 환경과 모바일 호스트들의 핸드오프 확률에 따라서 적응적으로 페이징 도메인을 구성할 수 있고 핸드오프 확률을 기반으로 단계적으로 페이징을 실시한다. 그리고 본 논문에서는 광장과 같이 이동 패턴이 자유로운 개방된 환경과 도심과 같은 이동 패턴이 제한된 실제 도심 중심지 환경을 기반으로 제안한 기법에 대한 실험을 실시하였다. 실험 결과 본 논문에서 제안한 기법은 비교 기법에 비하여 전체적으로 우수한 성능을 보였고, 특히 호 요청비율이 많은 실제 도심 환경에서 더 좋은 성능을 보였다.
