移动终端设备的快速发展和Ad hoc网络组网方便的特点使得Ad hoe网络有着广阔的应用前景，而组播路由技术在这些应用中起着非常重要的作用。本文综述了Ad hoe组播路由协议研究方面的一些最新工作，描述了设计Ad hoc组播路由协议所面临的问题，并着重对该研究开展以来所提出的各种主要组播协议进行了分类阐述和对比、分析，最后讨论了设计组播路由协议的几个主要问题，同时指出了未来的研究方向。

英文摘要：

Mobile terminals develop rapidly and Ad hoc networkf has the merit of convenient configuration,which makes it possible to deploy Ad hoc network widely in the future,furthermore, muhicasting plays an important role in the typical application with this type of network. This paper makes a survey of the recent works about multicast routing protocols for Ad hoc networks. Firstly ,the paper presents a unique set of challenges about multicasting that differ from traditional wired networks. Then, it describes the principles and comparisons of some main multicast routing protocols that are proposed in the literature. Finally, it discusses several issues of designing protocols and also suggests the research direction in muhicast routing for Ad hoc networks in the future.
