【摘要】 提出了一种基于内容的移动 Ad hoc 网络组播路由协议(简称 ACBCM)。ACBCM 协议使用了 Ad hoc 网络的簇结构,利用推—拉机制发布信息。协议中接收节点的集合由被组播的数据的内容决定,并随着组播内容的变化和接收节点的移动而变化。仿真结果表明,该协议信息开销小、组播成功率较高、网络的可扩展性好。更多还原

【Abstract】 In this paper we proposes a cluster-based content multicast routing protocol (ACBCM)in mobile Ad hoc net- works. ACBCM protocol makes use of cluster structure and employs push-pull mechanism to forward information. In this protocol, the content of the multicasting data decides the receiver set and this set changes according to the multieast content and the movement of the receiving nodes. The results of the simulations indicate that the information cost of the protocol is small, the multicast success rate is high.and the scalability to larger networks is good.更多还原
