초록

IEEE 802.11 무선랜에서 다중사용자 다이버시티 기법 위에 채널 다이버시티 기법을 적용함으로써 다중사용자 다이버시티 기법이 얻을 수 있는 최대 이득보다 더 큰 이득을 추구한다. 이를 위해 본 논문에서는 기존 다중사용자 다이버시티 기법 위에 수행될 기회적 채널 전환 기법을 제안하고 단말기의 수, 채널 수, 채널 전환 지연 시간, 사용자의 평균 채널 상태 등을 변경해가면서 성능 평가를 수행한다.

Channel diversity is exploited to increase multiuser diversity gains in IEEE 802.11 WLANs. To this end, we propose an opportunistic channel switching method and evaluate this with different number of stations, number of channels, switching latency, and the average channel condition of stations.
