여태 만든것이 다 날라가고...
새로이 실험으로 증빙된 올바른 소스와 정보만을 올리기로 한다.

NS2 실험을 위한 과정..

NS2는 본래 trace 파일을 가지고 원하는 데이터를 추출하기 위해 여러 동작을 하게 된다.
이러한 동작에 있어서 많은 노동의 고통이 따르기 때문에 나는 up_down_stream2.sh라는 쉘 스크립트 파일을 만들어 사용하였다.

아래는 up_down-stream2.sh 파일 내용이다.

위의 실험에 있어서
trace 파일은 drop이란 awk 스크립트 파일을 호출하여 재 필터링 된다.

drop을 필터링 하고 나면
총 처리량과 공평성 상태를 측정해야 한다.
처리량은 먼저 업스트림과 다운스트림을 측정한뒤 나머지를 산출한다.
awk-throughput이란 파일 명으로 생성된다.

#중요한 내용... 각 라우터와 AP간의 전파 딜레이가 너무 짧으면 세그먼트 에러 출력될 가능성이 높다. 이유는 그냥 추측만.... 또한 for문을 사용하여 스크립트 작성시 세그먼트 에러 출력될 가능성이 높다. 물론 문제없이 작성하더라도 말이다. 이유는 전혀 모르겠다. ㅎ
