WiBro는 IEEE 802.16에 이동성을 추가한 것으로서 현재 IPv4만을 지원하는데, IPv6를 적용할 경우 발생할 수 있는 문제점들은 최근에 이르러서야 이슈가 되고 있다. WiBro MAC은 IP 프로토콜 설계시 기본이 되는 이더넷과 많은 차이점이 존재한다. 망 구성요소들의 점대다(point-to-multipoint) 연결 형태와 상향링크 멀티캐스트 불가능으로 인해 정상적인 IP 멀티캐스팅/브로드캐스팅 동작이 어렵기 때문이다. 또한 이더넷과 같이 48비트 MAC 주소를 사용하는 것이 아니라 16비트 CID를 사용하기 때문에 IPv6를 적용할 경우 IPv6 Address Auto-Configuration, Neighbor Discovery, Duplicate Address Detection, Multicast Listener Discovery 등에서 정상적인 동작이 불가능하다. 이에 본 논문은 WiBro의 IPv6에서 MLD 프로토콜 적용방안과 무선자원을 효과적으로 사용하는 방법을 제시한다.
