첫번째로 작성한 코드이다. WLAN 환경으로 AP, MH를 구성했고 AP1,2,3과 P2P(주석처리) 링크를 구성했다.

그러나 P2P 부분에는 주소할당 오류가 자꾸 났고, WLAN 환경은 AP가 많아서 그런지 Eventmiss 오류가 자꾸 발생하였다.

(인터넷에 검색했으나 관련 글은 없었다.)

그래서 우선 P2P 부분은 주석처리를 하고 WLAN 부분은 알아보니 Adhoc Network로 구성해야함을 느꼈다.

다음 링크를 참고하면 Ad-hoc network의 뜻은 Mesh network라는 의미도 가지며, IRSML은 WMN 위에서 돌아간다는 정보를 논문에서 읽을 수 있었다.

(출처 : https://blog.naver.com/PostView.nhn?isHttpsRedirect=true&blogId=ki630808&logNo=221620151504)

따라서 WLAN 부분을 Adhoc NetWork로 교체하였다.

수정한 Adhoc Network Topo 이다. 일단 임시로 작동이 되는지 테스트를 하기 위해 GateWay를 구현하지 않고 Node 0으로 패킷을 전송하는 Application을 MH에 설치하였다.

이후 프로그램을 작동시켰으나 시뮬레이션 시간이 엄청 오래걸리는 이전과 동일한 현상이 발생했다.

결과가 나오면 이후 해결한 과정과 함께 코드를 다음 글에 첨부하도록 하겠다.
