초록

본 논문에서는 레일리 페이딩(Raylelgh fading)과 산란효과(Scattering effect), 원근효과(Near-far effect)를 고려한 무선 채널환경에서 CSMA/CD(Carrier Sense Multiple Access with Collision Detection) 시스템의 성능을 분석하였다. 또한 전파 특성에 따른 신호 전력의 불규칙성을 이용한 포획기술(capture effect)을 CSMA/CD 프로토콜에 적용시켰고, 마르코프(Markov) 모델링을 이용하여 성능의 향상 정도를 연구하였다. 그 결과 무선환경에 기인한 채널 오류만을 고려한 경우에는 CSMA/CD 시스템의 효율은 저하됨이 나타났으나 포획효과를 고려하면 시스템의 성능이 향상됨은 물론, 시스템이 매우 안정화됨을 확인하였다.

In this paper we analyzed, using Markov modeling, the performance of CSMA/CD over the wireless channel which is characterized by near-far effect, shadowing and Rayleigh fading. The analysis shows that throughput of CSMA/CD is degraded by channel error. However, if capture effect which arises from the randomness of power level of received signal due to the fading phenomena of electromagnetic waves is taken into consideration, the system performance is much improved and the system stability is also made better.
