Abstract

Various schemes for mobility are currently studied in ITU-T, 3GPP, IETF, and so on. Mobility support in NGN for seamless service is necessarily required. Currently proposed mechanisms are MIPv6, $IP^2$, and Q.MMF. However the performance comparison of all existing schemes is not examined as yet. That is, the existing methods need to be compared according to each performance parameter. So, in this paper, we investigate and compare the performances of MIPv6, $IP^2$, Q.MMF to location registration. In addition, this paper presents the performance comparison of handover latency times. For this, we use NS-2 simulator. As a result of analysis, $IP^2$ shown the best performance as it is measured the minimum time and cost. And it has low handover latency time in comparison with other mechanisms.

현재 ITU-T, 3GPP, IETF 등에서 차세대 네트워크에 대한 연구가 활발히 진행되고 있다. 차세대 네트워크(NGN)에서 seamless service를 제공해주기 위해 mobility의 제공은 필수요소가 되었다. 이러한 mobility 기술로는 MIPv6, IP2, Q.MMF등이 있으나 아직 각 기술들이 갖는 이동성지원관련 성능을 분석하고 비교한 연구는 이루어지지 않고 있다. 따라서 각 성능 파라미터에 따른 제안된 방안들의 성능 비교가 요구된다. 이 논문은 MIPv6, IP2, Q.MMF의 mobility 과련 동작을 살펴보고, 각 메커니즘들의 위치등록 과정 동안 소요되는 시간과 비용을 조사하고 비교한다. 또한 NS-2를 이용한 시뮬레이션을 통해 각 프로토콜에서 핸드오버 시 발생하는 지연을 비교한다. 그 결과 위치등록 과정 동안 소요되는 시간과 비용 면에서 IP2가 다른 메커니즘들보다 좋은 성능을 보였다. 시뮬레이션을 통해 알아본 핸드오버 지연시간 면에서도 IP2가 가장 좋은 성능을 보였다.
