Abstract

IEEE 802.11 wireless network supports control frames like RTS/CTS(Request To Send / Clear To Send). Because they is defend to frame collection problems. It helps to solve the frame collection problem but decreases the throughput rate. Also, control frame makes False Node Problem. This problem is makes to other wireless nodes don't work and don't find channels in the same cell and near cells. We proposed a reformed new control frame for efficiency throughput rate and solution of False Node Problem. New control frame is to have added to 4 bytes of channel detection ability at the RTS frames. Channel detection ability supported to check channel at the wireless node start to transmit data frame, We expect that channel detection ability make prevent False Node Problem for increase to access number to channel. We perform comparative analysis in terms of delay(sec) and load(bits/sec) with reform RTS/CTS method which proves the efficiency of the proposed method.

IEEE 802.11 무선 네트워크에서는 프레임 충돌현상을 방지하기 위해 RTS/CTS와 같은 제어프레임을 지원한다. 하지만 제어프레임은 프레임 충돌 현상을 막지만 전송률을 떨어뜨린다. 또한, 이웃하는 셀이나 같은 셀에 있는 다른 노드들의 동작을 막아버리는 현상인 False Node Problem을 발생시키기도 한다. 비효율적인 전송률과 False Node Problem을 해결하기 위해 새로운 제어프레임을 제안한다. 새로운 제어 프레임은 기존의 프레임에서 채널 감지기능을 갖는 4바이트를 추가한 것이며, 채널 감지 기능은 데이터를 수신할 때 일정한 시간에 채널을 다시 감지한다. 이 기능으로 채널의 접속 빈도를 높이게 되어 False Node Problem을 방지할 것이라고 기대한다. False Node Problem 방지와 효율적인 전송률을 증명하기 위해 새로운 제어프레임과 기존의 제어프레임을 지연시간과 load을 비교 분석을 하였다.
