摘要

本研究考察了在移动自组织网络(MANET)环境中不同视频格式(MPEG与运动JPEG或MJPEG)中不同编码方案(可扩展与多重描述或MD)的扩展使用，并提出了一套不同编码级别的冗余解决方案。仿真和分析演示和解释了编码方案、视频格式、冗余级别和数量、移动设备的移动性、CPU负载和电池寿命以及接收端的帧损失率之间的关系。最后，使用两个实际场景来说明这些发现和提出的解决方案。

The Effects of Mobility and Redundancy on Wireless Video Streaming over MANETs

This study examines the extended use of different coding schemes (Scalable vs. Multiple Description or MD) in different video formats (MPEG vs. Motion JPEG or MJPEG) in a Mobile Ad Hoc Network (MANET) environment and proposes a set of redundancy solutions at different coding levels. Simulations and analysis demonstrate and explain the relationship among the coding schemes, video formats, level and amount of redundancy, mobility of mobile devices, CPU load and battery life and frame loss rate at the receiver side. Finally, two practical scenarios are used to illustrate these findings and proposed solutions.
