초록

본 논문에서는 유럽의 ETSI(European Telecommunication Standards Institute)에서 표준화를 진행 중에 있는 유럽형 고속 무선 근거리 통신망인 HIPERLAN(HIgh PErformance Radio Local Area Network) 타입 1의 채널접근제어 프로토콜인 EY-NPMA(Elimination Yield - Non-preemptive Priority Multiple Access)프로토콜의 성능을 분석하였다. 본 논문에서는 EY-NPMA 프로토콜의 분석을 위해 시스템 모델을 설정하였으며, 채널접근 시도에서 성공할 확률과 경쟁 단계의 평균 길이를 분석하였다. 또한 M/G/1 대기행렬 모델을 사용하여 정규화된 지연시간과 처리율을 근사화 하였으며, 이러한 분석결과를 시뮬레이션을 통해 검증하였다.

In this paper, we analyzed the performance of EY-NPMA(Elimination Yield-Non-preemptive Priority Multiple Access) protocol-channel access control protocol of HIPERLAN(HIgh PErformance Radio Local Area Network) type 1 specification, adopted as european high speed wireless LAN standard by ETSI(European Telecommunication Standards Institute). We established a system model for EY-NPMA protocol analysis, analyzed success probability in a channel access cycle, and derived expressions for the average length of contention phase. Using a M/G/1 model, we approximated the normalized delay, and throughput, and we evaluated these results by simulations.
