Abstract

WMN is highlighted as a next generation network technology due to relatively reasonable cost to be built, compared with the pre-existing wireless network. It also enables same kind of network or even other kind of network to be integrated. Some WMN researches support mobility using router protocol such as AODV and DSR because WMN has the similar features with Ad-hoc network in terms of operation. However, WMN has got different operations with additional functions of multi-interface and internet connect, it can't be a good method to manage efficient mobility any more. This study suggests method to apply MAP function of HMIPv6 to WMN as a way to manage WMN mobility. Through simulation, operation was verified and function was appreciated. Through the results of evaluation, the suggest mobility management had shorter handover delay and packet loss reduced, which improved whole network throughput rate, compared with mobility management using AODV.

무선 메쉬 네트워크(WMN)는 기존의 무선 네트워크에 비해 저렴한 비용으로 빠르게 구축할 수 있는 장점 때문에 차세대 네트워크 기술로 부각되고 있으며 동일 네트워크는 물론 이종 네트워크간의 통합을 가능하게 한다. 현재 몇몇의 WMN 연구에서는 WMN과 애드 혹 네트워크의 유사한 특징 때문에 AODV, DSR과 같은 애드 혹 라우팅 프로토콜을 사용하여 이동성을 지원하고 있다. 그러나 WMN는 다중 인터페이스와 인터넷과 연결 등의 기능이 추가되어 기존 애드 혹 네트워크와는 작동 과정이 다르기 때문에 효율적인 이동성 관리를 지원하기 위한 방안으로는 적합하지 않다. 본 논문에서는 WMN의 이동성 관리를 지원하기 위한 방안으로 HMIPv6의 MAP 기능을 WMN에 적용하는 방안을 제안하고 시뮬레이션을 통해 동작 검증 및 성능 평가를 하였다. 평가된 결과를 통해서 제안한 이동성 관리가 AODV를 이용한 이동성 관리에 비해 짧은 핸드오버 지연과 패킷 손실이 감소하며 이를 통하여 네트워크 전체의 처리율 또한 향상됨을 확인할 수 있었다.
