Ad Hoc网络中的多播路由协议

无线Ad Hoc网络是指一组无线移动节点组成的多跳的,临时性的,无基础设施支持的无中心网络。多播是一种面向群组计算的通信传播方式,它使用单一的源地址把数据发给一组主机。如何在移动自组网中实现有效的多播路由技术是当前此领域研究中亟待解决的问题。文中对当前一些典型的多播路由协议进行了研究,并对它们各自的工作方式进行了分析,最后对它们各自的特点进行了比较。

Multicast Routing Protocols in Ad Hoc Networks

Ad Hoc wireless network is a multi-hop, temporary and non-central network without infrastructure to support which consists of a group of wireless mobile nodes. Multicast is a group-oriented communication transmission mode, and it uses a single source address to send data to a group of hosts. How to realize effective multicast routing algorithms is an urgent problem which needs to be solved in this research field. In this paper, current several typical multicast routing protocols are described and studied, their own working ways are analyzed and their characteristics are compared.
