본 논문에서는 IEEE 802.11 을 기반으로 하는 무선 Ad Hoc 망에서 데이터의 송신자 노드와 목적지 노드의 중간 노드들의 전송을 방해하고 채널을 경쟁하는 경쟁노드들이 Shortestpath 라우팅 경로 설정에 미치는 영향을 분석한다. 데이터를 전송하는 중간 노드들이 다수의 경쟁노드를 가지고 있을 경우 MAC delay 가 큰 변수로 작용하며 multihop 환경이기 때문에 hidden terminal 문제가 발생한다. 또한 AODV 와 같은 ondemand 라우팅 알고리즘은 경로를 찾기 위해서 Route Request 패킷을 브로드캐스트 하는데 이때 브로드캐스트 패킷의 성공적인 전송이 보장되지 않기 때문에 경쟁노드의 방해가 심한 경우 경로를 찾는데 실패할 가능성이 높아진다. 본 논문에서는 이러한 특성들을 근거로 경쟁노드의 수와 분포가 라우팅 경로 선택에 영향을 미친다는 것을 지적한다.
