초록

항공기, 보트, 열차 그리고 자동차와 같이 이동성 있는 네트워크들 안에서의 이동노드들은 함께 움직이며 같은 이동성을 공유한다. 따라서 본 논문에서는 네트워크 모빌리티 안의 이동노드들 공동의 이동성을 토대로 한 효율적인 위치관리기법을 제안한다. 또한 이동노드가 바인딩 갱신 메시지를 이동노드와 통신 중인 노드들 (correspondent nodes)에게 전송할 때 멀티캐스트 기법을 적용하여 이동노드나 이동노드와 통신 중인 노드들의 증가에도 일정한 바인딩 갱신 메시지만을 발생시킴으로써 효율적인 위치관리를 할 수 있다. 제안한 기법에 대한 분석모델을 기존의 연구들인 HMIPv6 (Hierarchical Mobile IPv6)와 NEMO (Network Mobility)와 비교 분석함으로써 효율성을 검증한다.

Mobile nodes are change their point of attachment dynamically such as networks deployed in aircraft, boats, trains, and cars. These mobile nodes move together and share the same nobility properties. Therefore, this paper addresses an efficient location management scheme based on collaboration of mobile nodes to a mobile network. We propose a scheme that combines multicast routing with Mobile IPv6 to support mobile network in the internet. This paper also tests the usefulness of our proposed method using analytical models and compares the results with our scheme and HMIPv6(Hierarchical Mobile IPv6) and Network Mobility(NEMO).
