摘要
在移动Ad Hoc网络中进行视频传输,组播技术起着非常重要的作用。设计移动Ad Hoc网络视频组播协议的一个重要目标就是保证传输的不间断性,降低接收到的无用视频帧的比例。对移动Ad Hoc网络中基于多树的视频组播协议进行了研究,介绍了视频编码技术,给出了多树视频组播路由协议的设计要求和衡量协议性能的度量指标,详细分析和比较了已有的几个多树视频组播协议,指出了它们的优缺点,并探讨了下一步的研究方向。
Multicast is a critical technology applied in video transmission over Ad Hoc network, and has gained a wider recognition among the public. One important object of designing mobile Ad Hoc networks video multicast protocol is guarantee the continuous reachability, and reduce the ratio of bad frames. The multiple tree video multicasting is researched over mobile Ad Hoc networks, and video coding technology is introduced, from the following aspects: Video coding technology, design requirements of routing protocol for the multiple tree video multicasting, metrics for measuring the protocol performance, analysis and comparison between the existing protocols, and further proposals for future study.
