Abstract

In this paper, we propose an enhanced handoff support scheme based on network-based mobility management protocol, Proxy Mobile IPv6 (PMIPv6), which is actively standardized by the IETF NETLMM working group. By utilizing the dynamic virtual hierarchy network architecture between mobile access gateways (MAGs), the proposed scheme can support network scalability and reliability to wireless access network. In addition, we propose pre-authentication process based on the policy store (PS) to support a fast and seamless handoff. We evaluate the performance of the proposed scheme in terms of handoff delay and end-to-end delay thru computer simulation. Thru, various computer simulation results, we verified the superior performance of the proposed scheme by comparing with the results of other schemes.

본 논문에서는 IETF NetLMM WG에서 표준화되고 있는 Proxy-MIPv6을 기반으로, 빠르고 효율적인 핸드오프를 지원하는 망 기반의 이동성 지원 방안을 제안하였다. 제안된 방식은 Mobile Access Gateway (MAG)간의 dynamic virtual hierarchy 망 구조를 활용함으로써 망의 확장성과 안정성을 제공하고, Policy Store(PS) 기반의 빠른 인증 및 프로파일 획득 기법을 활용함으로써 빠르고 효율적인 핸드오프를 제공할 수 있다. 또한, 제안된 방식과 기존의 PMIPv6의 성능 분석 및 토의를 통하여 제안된 방식의 우수성을 알 수 있다.
