Abstract

Recently, real time services have been demanding a lot and the number of mobile devices is increasing extremely. Many researchers are focusing on decreasing handoff or signaling cost, produced when mobile devices are moving around. With these efforts, HMIPv6(Hierarchical Mobile Internet Protocol Version 6) was proposed. Mobile nodes do not need to register their locations to Home Agents whenever crossing over subnets within a MAP domain. In HMIPv6, mobile nodes choose the farthest MAP without considering node mobility pattern. However, a large MAP domain is not always efficient for a slow moving node and required additional work to choose a MAP in HMIPv6. Hence, this paper proposes 'Performance Analysis of HMIPv6 applying adaptive MAP Domain Site'.

최근 실시간성이 요구되는 서비스나 이동 단말기의 폭증으로 인하여 노드 이동 시에 발생하는 핸드오프나 시그널링 비용을 줄이기 위해 제안된 프로토콜이 HMIPv6이다. HMIPv6에서 이동 노드가 동일한 MAP도메인 영역내외 서브넷들을 이동할 시에는 대응 노드나 흠 에이전트에 위치 등록을 수행할 필요가 없으며, 단지 MAP에게만 그 위치를 등록하게 된다 그러나, HMIPv6에서 선택한 거리기반 MAP 선택 방법에서는 이동 노드 패턴에 관계없이 이동 노드에서 거리가 가장 먼 MAP을 선택하여 큰 크기의 MAP 도메인이 형성되도록 하는데 이러한 경우, MAP 선택을 위한 오버헤드와 그 사이의 핸드오프 딜레이가 발생하며 비효율적으로 항상 큰 크기의 MAP 도메인이 형성된다. 따라서, 본 논문에서는 이동 노드의 한 서브넷 내의 상주시간에 따라 이동 노드의 이동 패턴을 고려하여 노드마다 다른 크기의 MAP 도메인이 형성되도록 하는 방법을 제안한다.
