Abstract

무선 네트워크에서 효율적인 이동성관리는 모바일 사용자의 지원에 상당히 중요하다. 몇몇의 이동성관리 기법들은 MN(Mobile Node)의 시그널링 트래픽을 줄여주는 목적으로 제안되었다. 그 중에서 PMIPv6(Proxy Mobile IPv6)는 호스트 기반의 이동성관리 프로토콜과 유사하지만 MN에게 이동성에 대한 어떠한 처리도 요구하지 않는다. MAG(Mobile Access Gateway)와 LMA(Local Mobility Anchor)같은 새로운 모바일 에이전트를 도입하여 MN에게 IP 이동성을 제공한다. 본 논문에서, MN 이동성의 종류에 따라 호출 당 평균 시그널링 지연과 평균 대역폭을 평가하는 분석 모델을 제안한다. 수학적 분석의 결과로 MF-PMIP(Multicasting-based FastPMIP)는 거의 모든 성능평가 매개변수에 대하여 D-PMIP에 비해 우수한 성능을 보여준다. In wireless networks, efficient mobility management to support of mobile users is very important. Several mobility management schemeshave been proposed with the aim of reducing the signaling traffic of MN(Mobile Node). Among them, PMIPv6 (Proxy Mobile IPv6) is similar with host-based mobility management protocols but MN does not require any process for mobility. By introducing new mobile agent like MAG (Mobile Access Gateway) and LMA (Local Mobility Anchor), it provides IP mobility to MN. In this paper, we propose the analytical model to evaluate the mean signalingdelay and the mean bandwidth according to the type of MN mobility. As a result of mathematical analysis, MF-PMIP (Multicasting-based FastPMIP) outperforms compared to F-PMIP and PMIP in terms of parameters for the performance evaluation.
