초록

최근 Wi-Fi 기능이 내장된 휴대용 장비가 제공하는 다양한 자료와 멀티미디어 서비스가 점점 늘어나고 있으며, 어디서든 인터넷에 접속하려는 전반적인 요구가 급격히 증가하고 있다. 이에 따라 네트워크에 많은 비용 부담이 증가하고 있다. 따라서, 모바일 네트워킹에 관한 최근의 연구 중 에너지 효율적인 네트워크 이동성 기술은 큰 주목을 받고 있다. 네트워크 이동성 환경에서 비용 효율적인 프로토콜 설계는 이동성 시그널링과 패킷 전달, 그리고 비용 효율성의 중요한 이슈 중의 하나인 유, 무선에서 제한된 네트워크 대역폭을 절약하여 불필요한 비용을 감소시키는 것이다. 본 연구에서는 기존의 네트워크 이동성 기법에 멀티캐스팅을 지원하는 고속 핸드오버, 효율적인 도메인간 이동성 관리와 패킷 전달 메소드를 제공하는 비용 효율적인 기법을 제안한다. 본 논문에서는 위치 갱신 비용과 패킷 터널링 비용을 합한 총 비용의 관점으로 기존의 NEMO 기법인 N-PMIPv6, rNEMO, PR-NEMO의 성능과 새롭게 제안하는 Fast PR-NEMO의 성능을 비교 분석하고, 제안된 기법이 기존 제안된 기법들에 비해 총 비용이 낮은 가장 에너지 효율적인 방식임을 증명한다.

In recent years, there are many data and multimedia services that are supported by WiFi-enabled mobile devices. As a result, the demand for the ability to connect to the Internet anywhere is rapidly increasing and network infrastructure is becoming increasingly important. The design of cost-efficient network mobility (NEMO) protocol is intended to reduce the demand for limited wired/wireless network bandwidth at the signaling of mobility support and packet delivery operations. In this paper, we propose a cost-effective inter-LMA domain mobility management scheme which provides fast handover with multicasting support in NEMO environments. And our Fast PR-NEMO scheme is compared with N-PMIPv6, rNEMO, and PR-NEMO. In conclusion, our proposed scheme shows the best performance in terms of location updating cost, and packet tunneling cost.
