Abstract

We propose a new resource reservation scheme called MC-HMRSVP(Mobile clustering based-Hierarchical mobile ReSource reserVation Protcol) that is an extension of HMRSVP[3,4]. MC-HMRSVP always establishes a virtual cluster called Mobile Cluster, which includes its immediately adjacent MA(Mobile Agent) for passive reservation as well as the current MA for active reservation to which MH(Mobile Host) belongs. Our scheme also establishes the MC regardless of intra/inter region movement by GMA(Gateway Mobile Agent) function when a MH moves. To provide a general formulation on analyzing the performance in terms of reservation cost, we also model the resource reservation cost by using a simple recursive equation. Then, we show that our scheme decreases the reservation cost in comparison with the existing HMRSVP extentions.

본 논문에서는 HMRSVP(Hierarchicl Mobile ReSource reserVation Protcol)[3,4]에서 확장된 새로운 이동 클러스 기반의 HMRSVP(MC-HMRSVP : Mobile Cluster based HMRSVP) 기법을 제안한다. MC-HMRSVP 는 이동 호스트 (MH : Mobile Host) 가 현재 이동 에이전트(Mobile Agent) 지역에 도착할 경우 해당 지역은 active 예약을 하고 이웃한 MA 는 passive 예약을 한다. 여기서 active MA와 passive MA 지역을 이동 클러스티 (Mobile Cluster) 또는 가상 클러스터라 부른다. MC-HMRSVP는 또한 MH가 다른 MA 로 이동하는 것에 관계없이 GMA(Gateway Mobile Agent) 기능에 의해 이동클러스터를 설정한다. 본 연구에서는 자원 예약 비용 관점에서 기존에 제안되어진 HMRSVP extension 들과 성능 비교를 위해 단순한 재귀 방정식을 이용한 자원 예약 비용 분석 모델을 만들었다. 결과적으로 MC-HMRSVP 기법이 낮은 예약비용을 나타내는 것을 보았다.
