摘要
使用移动IP协议可以使主机移动到Internet的任何区域都能够保持与其它节点之间的通信。IP组播能够高效传输大量数据到一组接收者,可有效利用网络带宽。随着大量移动设备接入Internet,支持主机移动的组播协议已成为人们研究的问题之一。文章首先给出评价支持主机移动的组播协议性能的标准,然后详细介绍了目前已经提出的主要移动组播协议,并进行了性能分析和对比,最后探讨了移动组播的研究方向和发展趋势。
Host can keep connecting with other communication nodes by Mobile IP protocol while it moves to another place in Internet.IP multicast can efficiently delivery a large amount of packets to a group of receivers.With more and more mobile devices connected into Internet,multicast protocol that supports host's mobility has become one of many people's research interests.This paper provides some important aspects in evaluating mobile multicast protocols,and pre-sents several existing mobile multicast protocols in detail;also this paper analyzes and compares their performances.Fi-nally,perspectives in the development of mobile multicast protocol are presented.
