中文摘要：
提出一种在车辆自组织网络（ VANET ）中应用的无线多跳视频传输实验系统的设计和实现方案及其对应的传输控制和路由选择协议．该系统将嵌入式Linux与IEEE 802．11 n传输协议集成到ARM内核，由S3 C6410主控模块、无线局域网网卡及LCD屏等构成．针对VANET的无线多跳视频传输场景，对视频编译码分别采用H．264和JPEG两种标准实现并对它们的压缩比、时延、传输丢包率等性能进行了理论分析和实验比较，进行了室内室外多种不同场景的实际测试．结果表明：所设计的多跳视频传输实验系统方案能够适应VANET等多种场景的应用，所提出的传输控制和路由选择协议能够保证视频传输的多跳和实时性要求．
英文摘要：
Abts ract A wireless mutl i-hop videot ransmission experiment system is designed and implemented for vehiculra ad-hoc networks VANET and the rt ansm ission control protocol and routing protocol are proposed. This system in tegrates the embedded Linux system witha n ARM kernel and oc ns ists of a S3C6410 main control module a wirel ss local arean etwork WLAN card a LCD screne and so on.In the scenario of a wireless multi-hop video transmission both the H.264 and JPEG are used and their performances such as the compression rate delay and frame loss rate are analyzed in theory andc ompared in the experiment.The system is tested in the real indoor and outdoor environment.The results show that the scheme of the multi-hop video transmission experiment system can be applicable for VANET and multiple scenes and the transmission control protocol and routing protocol proposed can achieve real-time transmission and meet multi-hop requirements.
