Abstract

In this paper, CSMA/CA with bridging is analyzed which is an added function of relaying directly between access points when wireless terminals can not communicate each other, and is also compared to the CSMA/CA without bridging which is IEEE 802.11 MAC standard. Through simulations, it is shown that the two methods have the similar performance in terms of the throughput but the bridging CSMA/CA improves the delay compared to the non-bridging CSMA/CA.

본 논문에서는 IEEE 802.11 매체 접속 제어 표준안인 CSMA/CA 프로토콜과 무선 단말기간 직접 통신을 불가능할 경우 접속점이 프레임을 중계해주는 브리지 기능을 갖는 CSMA/CA 프로토콜에 대하여 성능을 평가하고 비교하였다. 시뮬레이션 결과 브리지형 CSMA/CA 프로토콜은 기본의 비브리짓형 CSMA/CA에 비하여 전송 효율은 비슷하였지만 브릿지형 CSMA/CA이 전송 지연이 단축되어 성능이 개선됨을 확인하였다.
