Abstract

CCFH(Candidatecasting Fast Handoff) algorithm excels the performance of existing fast handoff schemes using multicasting in terms of handoff latency and B/W efficiency. The scheme uses L2 information(BSSID) at Wireless LAN and starts multicasting before L2 handoff. So it can reduce L3 handoff latency. At this article, we would show that Candidatecasting Fast Handoff Scheme is clearly new scheme using L2 information and has the good performance.

CCFH(Candidatecasting Fast Handoff) 알고리듬은 기존의 Mobile IP에 멀티캐스팅을 결합한 고속 핸드오프의 성능을 능가하며, B/W 효율성 측면에서 역시 뛰어난 성능을 보이는 새로운 핸드오프 방법이다. 이 알고리듬은 L2 정보를 이용, L2 핸드오프가 발생하기 전 미리 멀티캐스팅하여 L3 핸드오프 지연을 타 방법에 비해 획기적으로 줄인다. 본 논문에서는 제안된 핸드오프 방법을 소개하고, 기존 MIP(Mobile IP)의 기본적인 핸드오프 방법뿐만 아니라 다른 핸드오프 방법들과의 비교 분석을 통하여 제안된 방법의 성능이 우수함을 확인한다.
