Abstract

Several mobility supporting protocols have been proposed across OSI reference layers. Each protocol has similar or different characteristics based on its operating layer which affect a handover latency. In this paper, we analyze handover performance of most representative protocols in each layer. For analysis, we use SUBNET model based Markovian model and movement model. In result, difference of protocol handover latency is not occurred by DAD but also by security, movement detection, message processing time.

OSI 참조 모델에 따라 각 계층에 여러 개의 이동성 지원 프로토콜들이 제안 되어 왔다. 각 프로토콜이 작동하는 계층의 특징은 핸드오버 지연시간에 영향을 끼친다. 본 논문은 MN의 이동 패턴에 따른 각 계층에서 작동하는 대표적인 프로토콜들(MIPv6, mSCTP, SIP)의 핸드오버 성능을 비교 분석한다. 성능 분석을 위해 Markovian 모델에 기반한 서브넷 모델과 한 세션 동안 MN의 이동 모델을 사용하였다. 분석 결과 DAD도 핸드오버에 중요한 요인이지만 프로토콜간의 차이는 보안과 움직임을 감지하기 위한 시간, 메시지의 처리 시간 등에 의해 유발됐음을 알 수 있었다.
