Abstract

Due to the frequent and unpredictable topology changes, multicast still remains as challenge and no one-size-fits-all protocol could serve all kinds of needs in mobile ad hoc network. In this paper, we propose a novel scheme of Hierarchical Eulerian Ring Oriented Multicast Architecture (HEROMA) over mobile ad hoc network. It has features that concentrate on efficiency and robustness simultaneously. It is also an application-driven proposal for hazard detection. Architectures including Eulerian ring, hierarchy and multicast agent are investigated in detail Simulation results different level of improvements on control traffic, end-to-end delay and packet delivery ratio by comparing with tree-based and mesh-based multicast protocols.

예상치 못한 에드혹 망의 접속형태의 변경이 동반되는 멀티캐스트 라우팅 프로토콜에 대한 연구에 많은 과제를 남겨놓고 있으며, 다양한 이동 에드혹 망에 적합한 프로토콜에 대한 연구의 필요성이 제기되고 있다. 본 논문에서는 계층적 Eulerian 링 멀티캐스트 구조를 갖는 새로운 프로토콜을 제안한다. 제안한 구조는 Eulerian 링, 계층구조, 멀티캐스트 에이전트를 갖으며 기존의 방법보다 효율적이며 안전한 특성을 갖는다. 제안한 구조는 트리기반 및 메시기만 멀티캐스트 프로토콜과 비교하여 제어트래픽의 양, 점대점 지연, 패킷전송률 등에 있어 우수함은 시뮬레이션을 통해 입증한다.
