본 논문에서는 Ad Hoc 네트워크에서의 라우팅 알고리즘인 TORA 의 라우팅 유지관리 방법에서 발생하는 비효율적인 컨트롤 패킷들을 줄이는 방법을 제안한다. Adv-TORA에서는 DN(Downstream)이 소멸되는 노드에서 STP(Stop) 패킷을 주변 노드에 발송하여 끊어진 경로로 데이터 패킷이 발송되는것을 사전에 방지한다. 또, DN 소멸 노드의 주위에서 그래프의 재구성 작업이 일어났던 TORA 와는 상이하게, 단순히 지역적 라우트 경로를 초기화시킴으로서 TORA 의 컨트롤 패킷 부담을 줄인다. 또한, 통신에 참여하지 않는 노드들의 불필요한 라우트 정보 유지를 최소화하고, 라우트 요구 발생시에만 라우트 재구성 작업을 수행한다.
