摘要
随着组播应用的增加、无线通信技术的发展成熟和移动设备的普及,传统的因特网如何与各种无线通信技术结合以便为各种移动主机设备提供移动性支持引起了人们的高度重视。文中针对移动因特网的可靠组播所面临的新问题以及相关研究现状进行了讨论,并在RingNet模型下提出了一个全新的可靠组播方案。该可靠组播方案以“局部组重传机制”来实现“全局的可靠组播”。这样可提供介于“绝对可靠”和“尽力而为”之间的“高可靠性”。
With the increase of multicast applications, the progress of wireless technology, and the popularization of mobile devices, it is highly expected to provide mobility support to mobile devices in mobile Internet. This paper investigates on new problems for reliable multicast in mobile Internet. Also proposes a new reliable multicast scheme based on the proposed RingNet model in mobile Internet. The reliable multicast protocol realizes'globally reliable multicast' by'retransmission mechanism with local-groups', which provides a'high reliability' between'absolute reliability' and'best-effort reliability'.
