有效和可靠多播在无线网络是一个难点问题,也是一个重要的研究课题.该文提出和评价了一种基于协议转接概念的可靠适应多播协议(RAMP) . RAMP协议支持一个适应无线网络的可靠多播分组传输,转接节点放置在多播树上,数据恢复在两个转接节点之间进行.最后,给出了RAMP协议的性能分析及与SRM协议的比较.仿真实践表明RAMP协议为多媒体多播传输提供了一种新的有效途径.
Efficient and reliable multicast in wireless networks is a difficult issue and an important research topic.This paper presents and evaluates a reliable adaptive multicast protocol (RAMP) based on the concept of protocol transfer.The RAMP protocol supports an adaptive wireless network , The relay node is placed on the multicast tree and the data recovery is carried out between the two transit nodes.Finally, the performance analysis of RAMP protocol and the comparison with SRM protocol are given.The simulation results show that RAMP The agreement provides a new effective way for multimedia multicast transmission.
