초록

한 노드에서 다수의 노드로 데이터를 전달하는 one-hop 통신에 사용되는 매체접속제어(MAC)는 멀티캐스트 기반의 데이터 통신을 사용하는 것이 매우 효율적이다. 유니캐스트와 달리 멀티캐스트에서는 모든 노드들과의 통신에서 우수한 품질을 얻기 위해서는 여러 노드들과의 서로 다른 무선 채널환경과 노드 이동성에 따른 무전 채널환경 변화에 대응할 수 있어야 한다. 하지만, IEEE 802.11에서는 다수개의 노드들과 RTS, CTS, ACK을 교환하는 방법이 정의되어 있지 않아서 신뢰성 있는 멀티캐스트를 지원하지 않고 있다. 이러한 문제를 해결하기 위해서 몇 가지 MAC 계층 프로토콜들이 제안되었다. 하지만, 신뢰성 있는 멀티 캐스트를 구현하기 위해서는 추가적인 오버헤드가 필요하며, 이 오버헤드로 인해서 시스템 성능이 저하하게 된다. 본 논문에서는 OFDMA 시스템에서 신뢰성 있는 멀티 캐스트를 구현하기 위해 필요한 오버헤드를 줄이기 위하여 계층통합적 (cross-layer) 설계기법을 제안한다. 제안된 오버헤드와 시스템 성능간의 관계를 분석하는 방법도 제안한다.

Multicast-based data communication is an efficient communication scheme in wireless networks where the Media Access Control (MAC) layer is based on one-hop broadcast from one source to multiple receivers. Compared with unicast, multicast over wireless channel should handle varying channel conditions of multiple users and user mobility to achieve good quality for all users. However, IEEE 802.11 does not support reliable multicast due to its inability to exchange RTS/CTS and ACK with multiple recipients. Thus, several MAC layer protocols have been proposed to provide reliable multicast. For the reliable multicast, an additional overhead is introduced and it degrades the system performance. In this paper, we propose a cross-layer design to reduce the control overhead for reliable multicast in OFDMA systems. We present an analytical formulation of the system throughput associated with the overhead.
