蓝牙个人区域网络视频流传输建模与仿真研究

Modeling and Simulation of Video Streaming over Bluetooth Personal Area Network

目前无线ad hoc网络发展的目标是支持多媒体数据的传输,基于ad hoc网络的视频流传输有着巨大的应用前景。但是无线传输介质的不稳定特性决定了其支持视频流传输存在较大的挑战。在分析蓝牙技术特点的基础上,对蓝牙无线ad hoc网络视频流传输进行建模。设计基于所提模型的网络视频流传输模拟实验架构。在不同码率和不同路径长度的模拟环境下测试解码视频流的质量,研究分析蓝牙视频流传输性能。

As wireless ad hoc network architectures are now targeted to support multimedia traffic, streaming video over these technologies will give rise to interesting applications, But the variable nature of the wireless medium will not lend itself easily to supporting video streaming. After brief introduction of Bluetooth characteristics, a video distortion based model was proposed for analyzing the performance of video streaming over Bluetooth wireless personal area networks. Then a simulation scheme for performing video streaming over wireless ad hoc networks was designed, Under different video stream rates and path lengths, simulations were carried out and the decoded video stream qualities were measured to analyze the performance of Bluetooth for video streaming.
