摘要
针对无中心多点通信中的视频传输,设计并实现了一种基于AODV路由协议的adhoc网络视频传输平台。利用V4L技术,实现了视频信息在adhoc网络中实时传输。硬件平台以ARMCor.tex-A8为内核的嵌入式系统结合摄像头捕捉图像信息,利用802.11协议族进行视频信息传输。在视频应用程序设计中采用了多线程技术和内存映射及复制。实验测试结果表明,视频信息能够稳定在目标机中运行,对于提高自组织网络中视频传输的应用具有重要意义。
Aimed at video transmission communication among no center nodes,we designed and implemented an ad-hoc network video communication platform based on AODV routing protocol. What’s more,using v4l technology,we achieved real-time transmission of video information in ad hoc network. The hardware platform combined ARM Cortex-A8 core embedded system and camera to capture the image information,and used the 802.11 protocol family to achieve video information transmission. In the video application design, we used multithreading, memory mapping and replication technology. Experimental tests showed that video information can be run in the target machine stably,thus providing an important significance for improving the application of self-organizing network video transmission.
