Abstract

ad-hoc network is self-constructed by mobile hosts without any infrastructure. And the hosts collaborate with each other for routing packet by means of multi-hop communication. But it is too hard to deploy ad hoc network at the large area because of the salability problem caused by low network throughput. network throughput decrease is due to contention on the air among the neighbor host and single interface limitation, and broadcast flooding through overall network. In this paper, to solve the ad hoc scalability problem, we propose mesh network based scalable hierarchical ad hoc architecture, and also propose the adaptation methods for inter-working with the host not including ad hoc functions and the legacy infra-network.

에드혹 네트워크는 통신기반 없이 일반 단말 만으로 자가 구성되며 단말 간 다중 흡 방식으로 패킷을 전송한다. 이러한 에드혹 네트워크는 광범위한 지역에 대한 적용이 어렵다. 이는 인접 단말 간 채널 접근 경쟁 및 단일 인터페이스로 인한 송, 수신 지연, 그리고 네트워크 전반에 걸친 방송메시지 전송으로 발생하는 자원 소모는 전반적 네트워크 전송률이 저하시키며 이는 결국 네트워크의 확장성을 제한하기 때문이다. 본 논문에서는 이와 같은 에드혹 네트워크의 확장성 저하 문제를 해결하기 위하여 상위 고정된 인프라를 기반으로 한 메쉬 네트워크와 하위 에드혹 단말들의 기존 메쉬 네트워크가 계층적으로 혼합된 확장성 있는 메쉬 네트워크 구조를 제안한다. 또한 제안된 메쉬 네트워크가 실 환경 네트워크에 구축되어 에드혹 단말이 아닌 일반단말의 메쉬 네트워크 수용 방안 및 외부 네트워크와의 연동을 위한 방안들을 제안한다.
