摘要: 针对大规模Ad Hoc网络中平面多播路由协议缺乏可扩展性的缺点,提出一种基于分层拓扑结构的多播路由协议。该协议借鉴基于网格按需多播路由协议适合高速运动的优点,采用EWCA簇算法对其拓扑结构进行分层管理。仿真实验验证了该协议适用于大规模 Ad Hoc网络。

Abstract: Aiming at the lack of extension of flat multicast routing protocols in Ad Hoc network of large scale, this paper proposes a multicast routing protocol based on hierarchical structure. The protocol refers to the advantages of fitness for high-speed movement of mesh-based on demand multicast routing protocol, and adopts an Enhanced Weighted Clustering Algorithm(EWCA) to manage its topology structure hierarchically. The simulation experiment proves that this protocol is suitable for Ad Hoc network of large scale.

Key words: On Demand Multicast Routing Protocol(ODMRP), Ad Hoc network, hierarchical structure, cluster algorithm
