초록
차세대 네트워크에서 이동성 지원을 위해 다양한 방식이 제시되고 있으나 이들의 성능이 상대적으로 비교된 바는 없다. 따라서, 본 논문에서는 MIPv6, IP2, Q.MMF, IMS 방식의 위치 등록 과정과 핸드오버 절차를 분석하고, 성능 분석을 위한 파라미터 및 시뮬레이션 방법을 이용하여 각각의 절차에 대한 등록 및 핸드오버 지연 시간과 비용 측면에서 성능을 비교 분석하였다. 결과적으로 위치관리자(Location Manager)가 코어 네트워크 상의 중심에 위치한 IP2가 다른 메커니즘들에 비해 가장 좋은 성능을 보임을 확인하였다.
Abstract
Various schemes for mobility support are currently proposed in NGN. However the performance comparison of all existing schemes is not relatively examined as yet. Therefore, in this paper, we investigate the location registration and handover procedure of MIPv6, IP2, Q.MMF, IMS, compare and analyze the location registration time and cost and handover latency time using various performance parameters and simulation for the performance analysis. As a result of analysis, when Location Manager locates in the center of core network, IP2 showed better performance than other schemes.
