移动Ad Hoc网络多播路由协议的研究进展

Progress of Multicast Routing Protocols for Mobile Ad Hoc Networks

移动AdHoc网络是一个自组织、移动节点通过无线链路组成的动态拓扑变化的网络.由于网络规模小、无基础设施、构建迅速等特点,从而广泛用于紧急事件、军事和民用领域以及多媒体应用等.随着网络应用规模的增长,在移动AdHoc网络中支持多播路由成为网络领域中一类重要的研究课题.该文综述了移动AdHoc网络多播路由方面的一些最新工作,论述了设计移动AdHoc网络多播路由协议的特性、问题和技术,详细描述和比较了目前典型的移动AdHoc网络多播路由协议,为进一步的应用和研究提出了新的课题.

Mobile ad hoc networks are self-organizing,dynamic topology networks formed by a collection of mobile nodes through radio links.Minimal configuration,absence of infrastructure,and quick deployment ,make them convenient for emergency situations other than military and civilian applications.Multicasting plays a very crucial role in the appli-cation of Ad hoc networks.As the number of participants increases,scalability of the multicast routing protocol becomes an important issue.This paper makes a survey of the recent works about multicast routing protocols for ad hoc net-works,presents a comprehensive review for multicast routing features,issues and techniques in mobile ad hoc networks and provides a detailed description and comparison of ad hoc multicast protocols.The discussion presented here will be helpful to application developers in selecting an appropriate multicast protocol and pave the way for further research.
