초록

차세대 무선 네트워크에서 MN의 글로벌 로밍을 효율적으로 지원하기 위해서는 원활한 핸드오버와 MN의 이동성관리는 매우 중요하다. IETF가 모바일 IPv6와 보다 확장된 IP 계층에서의 이동성관리를 제안하였지만 트래픽 특성 및 사용자의 MN에 따라 크게 좌우된다. 그러므로 이러한 요인에 관해 심도있는 성능을 평가하는 것이 중요하다. 일반적으로 IPv6 기반 이동성관리 프로토콜의 성능은 시뮬레이션을 통해 평가하는데 본 논문에서는 IPv6 기반 이동성관리 프로토콜의 성능을 평가하는 분석 프레임워크를 제안한다. 서브넷 체류 시간, 패킷 도착률과 무선연결 지연 등 시스템 매개변수들의 수학적 분석을 이용하여 핸드오프 지연, 패킷 손실에 대한 성능평가를 수행하고, 분석 결과를 통해 네트워크 매개변수와 성능분석 수치간의 상관관계를 제시한다.

Mobility management of the mobile nodes and provision of seamless handover is crucial to an efficient support for the global roaming of the mobile nodes in next-generation wireless networks. Mobile IPv6 and mobility management in extended IP layer, which highly depend on traffic characteristics and user mobility models, were proposed by the IETF. Therefore, to evaluate the in-depth performance about these factors is important. Generally, the performance of IPv6-based mobility management protocol is evaluated through simulation. This paper shows the correlation between network parameters and performance metrics through numerical results, which is investigated how influence handoff latency and packet loss. And this paper uses mathematical analysis of the system parameters, such as the subnet residence time, the packet arrival rate and delay in wireless connection through the analytical framework which evaluate the performance of IPv6-based mobility management protocol.
