초록

MIPv6, HMIPv6, FMIPv6와 같은 호스트 기반의 IPv6 이동성 지원 프로토콜들과 달리, Proxy Mobile IPv6 (PMIPv6)은 이동 노드의 개입없이 네트워크 엔티티들간의 협업 절차만을 사용하여 이동성 관리를 수행하기 때문에, IPv6 이동성 지원 프로토콜의 실질적인 도입을 촉진시킬 것으로 기대되고 있다. 본 논문에서는, MIPv6, HMIPv6, FMIPv6와 같은 대표적인 호스트 기반의 IPv6 이동성 지원 프로토콜들과 네트워크 기반의 IPv6 이동성 지원 프로토콜인 PMIPv6간의 핸드오버 지연시간을 분석 및 비교하고자 한다. 본 연구의 분석 결과, PMIPv6의 핸드오버 지연시간은 MIPv6 및 HMIPv6에 비하여 월등히 짧으며, 또한 무선링크상에서의 지연시간이 MAG와 LMA간의 지연시간보다 클 경우에는 PMIPv6에서의 핸드오버 지연시간이 FMIPv6에서의 핸드오버 지연시간보다 짧다는 것을 보여준다.

Unlike host-based IPv6 mobility support protocols such as Mobile IPv6 (MIPv6), Hierarchical Mobile IPv6 (HMIPv6), and Fast handover for Mobile IPv6 (FMIPv6), Proxy Mobile IPv6 (PMIPv6) is expected to accelerate the real deployment of IPv6 mobility support protocol by using only collaborative operations between the network entities without mobile node (MN) being involved. In this paper, we analyze and compare the handover latency of network-based IPv6 mobility support protocol (i.e., PMIPv6) with the representative host-based IPv6 mobility support protocols such as MIPv6, HMIPv6, and FMIPv6. Analytical results show that the handover latency of PMIPv6 is considerably lower than those of MIPv6 and HMIPv6, and the handover latency of PMIPv6 becomes lower than that of FMIPv6 in case the wireless link delay is greater than the delay between mobile access gateway (MAG) and local mobility anchor (LMA).
